## Installation
To get started with PR-Agent quickly, you first need to acquire two tokens:
1. An OpenAI key from [here](https://platform.openai.com/), with access to GPT-4.
2. A GitHub\GitLab\BitBucket personal access token (classic) with the repo scope.
There are several ways to use PR-Agent:
**Locally**
- [Using Docker image (no installation required)](INSTALL.md#use-docker-image-no-installation-required)
- [Run from source](INSTALL.md#run-from-source)
**GitHub specific methods**
- [Run as a GitHub Action](INSTALL.md#run-as-a-github-action)
- [Run as a polling server](INSTALL.md#run-as-a-polling-server)
- [Run as a GitHub App](INSTALL.md#run-as-a-github-app)
- [Deploy as a Lambda Function](INSTALL.md#deploy-as-a-lambda-function)
- [AWS CodeCommit](INSTALL.md#aws-codecommit-setup)
**GitLab specific methods**
- [Run a GitLab webhook server](INSTALL.md#run-a-gitlab-webhook-server)
**BitBucket specific methods**
- [Run as a Bitbucket Pipeline](INSTALL.md#run-as-a-bitbucket-pipeline)
- [Run on a hosted app](INSTALL.md#run-on-a-hosted-bitbucket-app)
- [Bitbucket server and data center](INSTALL.md#bitbucket-server-and-data-center)
---
### Use Docker image (no installation required)
A list of the relevant tools can be found in the [tools guide](./docs/TOOLS_GUIDE.md).
To invoke a tool (for example `review`), you can run directly from the Docker image. Here's how:
- For GitHub:
```
docker run --rm -it -e OPENAI.KEY=<your key> -e GITHUB.USER_TOKEN=<your token> codiumai/pr-agent:latest --pr_url <pr_url> review
```
- For GitLab:
```
docker run --rm -it -e OPENAI.KEY=<your key> -e CONFIG.GIT_PROVIDER=gitlab -e GITLAB.PERSONAL_ACCESS_TOKEN=<your token> codiumai/pr-agent:latest --pr_url <pr_url> review
```
Note: If you have a dedicated GitLab instance, you need to specify the custom url as variable:
```
docker run --rm -it -e OPENAI.KEY=<your key> -e CONFIG.GIT_PROVIDER=gitlab -e GITLAB.PERSONAL_ACCESS_TOKEN=<your token> GITLAB.URL=<your gitlab instance url> codiumai/pr-agent:latest --pr_url <pr_url> review
```
- For BitBucket:
```
docker run --rm -it -e CONFIG.GIT_PROVIDER=bitbucket -e OPENAI.KEY=$OPENAI_API_KEY -e BITBUCKET.BEARER_TOKEN=$BITBUCKET_BEARER_TOKEN codiumai/pr-agent:latest --pr_url=<pr_url> review
```
For other git providers, update CONFIG.GIT_PROVIDER accordingly, and check the `pr_agent/settings/.secrets_template.toml` file for the environment variables expected names and values.
---
If you want to ensure you're running a specific version of the Docker image, consider using the image's digest:
```bash
docker run --rm -it -e OPENAI.KEY=<your key> -e GITHUB.USER_TOKEN=<your token> codiumai/pr-agent@sha256:71b5ee15df59c745d352d84752d01561ba64b6d51327f97d46152f0c58a5f678 --pr_url <pr_url> review
```
Or you can run a [specific released versions](./RELEASE_NOTES.md) of pr-agent, for example:
```
codiumai/pr-agent@v0.9
```
---
### Run from source
1. Clone this repository:
```
git clone https://github.com/Codium-ai/pr-agent.git
```
2. Install the requirements in your favorite virtual environment:
```
pip install -r requirements.txt
```
3. Copy the secrets template file and fill in your OpenAI key and your GitHub user token:
```
cp pr_agent/settings/.secrets_template.toml pr_agent/settings/.secrets.toml
chmod 600 pr_agent/settings/.secrets.toml
# Edit .secrets.toml file
```
4. Add the pr_agent folder to your PYTHONPATH, then run the cli.py script:
```
export PYTHONPATH=[$PYTHONPATH:]<PATH to pr_agent folder>
python3 -m pr_agent.cli --pr_url <pr_url> review
python3 -m pr_agent.cli --pr_url <pr_url> ask <your question>
python3 -m pr_agent.cli --pr_url <pr_url> describe
python3 -m pr_agent.cli --pr_url <pr_url> improve
python3 -m pr_agent.cli --pr_url <pr_url> add_docs
python3 -m pr_agent.cli --pr_url <pr_url> generate_labels
python3 -m pr_agent.cli --issue_url <issue_url> similar_issue
...
```
---
### Run as a GitHub Action
You can use our pre-built Github Action Docker image to run PR-Agent as a Github Action.
1. Add the following file to your repository under `.github/workflows/pr_agent.yml`:
```yaml
on:
pull_request:
issue_comment:
jobs:
pr_agent_job:
runs-on: ubuntu-latest
permissions:
issues: write
pull-requests: write
contents: write
name: Run pr agent on every pull request, respond to user comments
steps:
- name: PR Agent action step
id: pragent
uses: Codium-ai/pr-agent@main
env:
OPENAI_KEY: ${{ secrets.OPENAI_KEY }}
GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
```
** if you want to pin your action to a specific release (v0.7 for example) for stability reasons, use:
```yaml
on:
pull_request:
issue_comment:
jobs:
pr_agent_job:
runs-on: ubuntu-latest
permissions:
issues: write
pull-requests: write
contents: write
name: Run pr agent on every pull request, respond to user comments
steps:
- name: PR Agent action step
id: pragent
uses: Codium-ai/pr-agent@v0.7
env:
OPENAI_KEY: ${{ secrets.OPENAI_KEY }}
GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
```
2. Add the following secret to your repository under `Settings > Secrets and variables > Actions > New repository secret > Add secret`:
```
Name = OPENAI_KEY
Secret = <your key>
```
The GITHUB_TOKEN secret is automatically created by GitHub.
3. Merge this change to your main branch.
When you open your next PR, you should see a comment from `github-actions` bot with a review of your PR, and instructions on how to use the rest of the tools.
4. You may configure PR-Agent by adding environment variables under the env section corresponding to any configurable property in the [configuration](pr_agent/settings/configuration.toml) file. Some examples:
```yaml
env:
# ... previous environment values
OPENAI.ORG: "<Your organization name under your OpenAI account>"
PR_REVIEWER.REQUIRE_TESTS_REVIEW: "false" # Disable tests review
PR_CODE_SUGGESTIONS.NUM_CODE_SUGGESTIONS: 6 # Increase number of code suggestions
```
---
### Run as a polling server
Request reviews by tagging your GitHub user on a PR
Follow [steps 1-3](#run-as-a-github-action) of the GitHub Action setup.
Run the following command to start the server:
```
python pr_agent/servers/github_polling.py
```
---
### Run as a GitHub App
Allowing you to automate the review process on your private or public repositories.
1. Create a GitHub App from the [Github Developer Portal](https://docs.github.com/en/developers/apps/creating-a-github-app).
- Set the following permissions:
- Pull requests: Read & write
- Issue comment: Read & write
- Metadata: Read-only
- Contents: Read-only
- Set the following events:
- Issue comment
- Pull request
- Push (if you need to enable triggering on PR update)
2. Generate a random secret for your app, and save it for later. For example, you can use:
```
WEBHOOK_SECRET=$(python -c "import secrets; print(secrets.token_hex(10))")
```
3. Acquire the following pieces of information from your app's settings page:
- App private key (click "Generate a private key" and save the file)
- App ID
4. Clone this repository:
```
git clone https://github.com/Codium-ai/pr-agent.git
```
5. Copy the secrets template file and fill in the following:
```
cp pr_agent/settings/.secrets_template.toml pr_agent/settings/.secrets.toml
# Edit .secrets.toml file
```
- Your OpenAI key.
- Copy your app's private key to the private_key field.
- Copy your app's ID to the app_id field.
- Copy your app's webhook secret to the webhook_secret field.
- Set deployment_type to 'app' in [configuration.toml](./pr_agent/settings/configuration.toml)
> The .secrets.toml file is not copied to the Docker image by default, and is only used for local development.
> If you want to use the .secrets.toml file in your Docker image, you can add remove it from the .dockerignore file.
> In most production environments, you would inject the secrets file as environment variables or as mounted volumes.
> For example, in order to inject a secrets file as a volume in a Kubernetes environment you can update your pod spec to include the following,
> assuming you have a secret named `pr-agent-settings` with a key named `.secrets.toml`:
```
volumes:
- name: settings-volume
secret:
secretName: pr-agent-settings
// ...
containers:
// ...
volumeMounts:
- mountPath: /app/pr_agent/settings_prod
name: settings-volume
```
> Another option is to set the secrets as environment variables in your deployment environment, for example `OPENAI.KEY` and `GITHUB.USER_TOKEN`.
6. Build a Docker image for the app and optionally push it to a Docker repository. We'll use Dockerhub as an example:
```
docker build . -t codiumai/pr-agent:github_app --target github_app -f docker/Dockerfile
docker push codiumai/pr-agent:github_app # Push to your Docker repository
```
7. Host the app using a server, serverless function, or container environment. Alternatively, for development and
debugging, you may use tools like smee.io to forward webhooks to your local machine.
You can check [Deploy as a Lambda Function](#deploy-as-a-lambda-function)
8. Go back to your app's settings, and set the following:
- Webhook URL: The URL of your app's server or the URL of the smee.io channel.
- Webhook secret: The secret you generated earlier.
9. Install the app by navigating to the "Install App" tab and selecting your desired repositories.

### Deploy as a Lambda Function
1. Follow steps 1-5 of [Method 5](#run-as-a-github-app).
2. Build a docker image that can be used as a lambda function
```shell
docker buildx build --platform=linux/amd64 . -t codiumai/pr-agent:serverless -f docker/Dockerfile.lambda
```
3. Push image to ECR
```shell
docker tag codiumai/pr-agent:serverless <AWS_ACCOUNT>.dkr.ecr.<AWS_REGION>.amazonaws.com/codiumai/pr-agent:serverless
docker push <AWS_ACCOUNT>.dkr.ecr.<AWS_REGION>.amazonaws.com/codiumai/pr-agent:serverless
```
4. Create a lambda function that uses the uploaded image. Set the lambda timeout to be at least 3m.
5. Configure the lambda function to have a Function URL.
6. In the environment variables of the Lambda function, specify `AZURE_DEVOPS_CACHE_DIR` to a writable location such as /tmp. (see [link](https://github.com/Codium-ai/pr-agent/pull/450#issuecomment-1840242269))
7. Go back to steps 8-9 of [Method 5](#run-as-a-github-app) with the function url as your Webhook URL.
The Webhook URL would look like `https://<LAMBDA_FUNCTION_URL>/api/v1/github_webhooks`
---
### AWS CodeCommit Setup
Not all features have been added to CodeCommit yet. As of right now, CodeCommit has been implemented to run the pr-agent CLI on the command line, using AWS credentials stored in environment variables. (More features will be added in the future.) The following is a set of instructions to have pr-agent do a review of your CodeCommit pull request from the command line:
1. Create an IAM user that you will use to read CodeCommit pull requests and post comments
* Note: That user should have CLI access only, not Console access
2. Add IAM permissions to that user, to allow access to CodeCommit (see IAM Role example below)
3. Generate an Access Key for your IAM user
4. Set the Access Key and Secret using environment variables (see Access Key example below)
5. Set the `git_provider` value to `codecommit` in the `pr_agent/settings/configuration.toml` settings file
6. Set the `PYTHONPATH` to include your `pr-agent` project directory
* Option A: Add `PYTHONPATH="/PATH/TO/PROJECTS/pr-agent` to your `.env` file
* Option B: Set `PYTHONPATH` and run the CLI in one command, for example:
* `PYTHONPATH="/PATH/TO/PROJECTS/pr-agent python pr_agent/cli.py [--ARGS]`
##### AWS CodeCommit IAM Role Example
Example IAM permissions to that user to allow access to CodeCommit:
* Note: The following is a working example of IAM permissions that has read access to the repositories and write access to allow posting comments
* Note: If you only want pr-agent to review your pull requests, you can tighten the IAM permissions further, however this IAM example will work, and allow the pr-agent to post comments to the PR
* Note: You may want to replace the `"Resource": "*"` with your list of repos, to limit access to only those repos
```
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": [
"codecommit:BatchDescribe*",
"codecommit:BatchGet*",
"codecommit:Describe*",
"codecommit:EvaluatePullRequestApprovalRules",
"codecommit:Get*",
"codecommit:List*",
"codecommit:PostComment*",
"codecommit:PutCommentReaction",
"codecommit:UpdatePullRequestDescription",
"codecommit:UpdatePullRequestTitle"
],
"Resource": "*"
}
]
}
```
##### AWS CodeCommit Access Key and Secret
Example setting the Access Key and Secret using environment variables
```sh
export AWS_ACCESS_KEY_ID="XXXXXXXXXXXXXXXX"
export AWS_SECRET_ACCESS_KEY="XXXXXXXXXXXXXXXX"
export AWS_DEFAULT_REGION="us-east-1"
```
##### AWS CodeCommit CLI Example
After you set up AWS CodeCommit using the instructions above, here is an example CLI run that tells pr-agent to **review** a given pull request.
(Replace your specific PYTHONPATH and PR URL in the example)
```sh
PYTHONPATH="/PATH/TO/PROJECTS/pr-agent" python pr_agent/cli.py \
--pr_url https://us-east-1.console.aws.amazon.com/codesuite/codecommit/repositories/MY_REPO_NAME/pull-requests/321 \
review
```
---
### Run a GitLab webhook server
1. From the GitLab workspace or group, create an access token. Enable the "api" scope only.
2. Generate a random secret for your app, and save it for later. For example, you can use:
```
WEBHOOK_SECRET=$(python -c "import secrets; print(secrets.token_hex(10))")
```
3. Follow the instructions to build the Docker image, setup a secrets file and deploy on your own server from [Method 5](#run-as-a-github-app) steps 4-7.
4. In the secrets file, fill in the following:
- Your OpenAI key.
- In the [gitlab] section, fill in personal_access_token and shared_secret. The access token can be a personal access token, or a group or project access token.
- Set deployment_type to 'gitlab' in [configuration.toml](./pr_agent/settings/configuration.toml)
5. Create a webhook in GitLab. Set the URL to the URL of your app's server. Set the secret token to the generated secret from step 2.
In the "Trigger" section, check the comments and merge request events boxes.
6. Test your installation by opening a merge request or commenting or a merge request using one of CodiumAI's commands.
### Run as a Bitbucket Pipeline
You can use the Bitbucket Pipeline system to run PR-Agent on every pull request open or update.
1. Add the following file in your repository bitbucket_pipelines.yml
```yaml
pipelines:
pull-requests:
'**':
- step:
name: PR Agent Review
image: python:3.10
services:
- docker
script:
- docker run -e CONFIG.GIT_PROVIDER=bitbucket -e OPENAI.KEY=$OPENAI_API_KEY -e BITBUCKET.BEARER_TOKEN=$BITBUCKET_BEARER_TOKEN codiumai/pr-agent:latest --pr_url=https://bitbucket.org/$BITBUCKET_WORKSPACE/$BITBUCKET_REPO_SLUG/pull-requests/$BITBUCKET_PR_ID review
```
2. Add the following secure variables to your repository under Repository settings > Pipelines > Repository variables.
OPENAI_API_KEY: <your key>
BITBUCKET_BEARER_TOKEN: <your token>
You can get a Bitbucket token for your repository by following Repository Settings -> Security -> Access Tokens.
Note that comments on a PR are not supported in Bitbucket Pipeline.
### Run using CodiumAI-hosted Bitbucket app
Please contact <support@codium.ai> or visit [CodiumAI pricing page](https://www.codium.ai/pricing/) if you're interested in a hosted BitBucket app solution that provides full functionality including PR reviews and comment handling. It's based on the [bitbucket_app.py](https://github.com/Codium-ai/pr-agent/blob/main/pr_agent/git_providers/bitbucket_provider.py) implementation.
### Bitbucket Server and Data Center
Login into your on-prem instance of Bitbucket with your service account username and password.
Navigate to `Manage account`, `HTTP Access tokens`, `Create Token`.
Generate the token and add it to .secret.toml under `bitbucket_server` section
```toml
[bitbucket_server]
bearer_token = "<your key>"
```
#### Run it as CLI
Modify `configuration.toml`:
```toml
git_provider="bitbucket_server"
```
and pass the Pull request URL:
```shell
python cli.py --pr_url https://git.onpreminstanceofbitbucket.com/projects/PROJECT/repos/REPO/pull-requests/1 review
```
#### Run it as service
To run pr-agent as webhook, build the docker image:
```
docker build . -t codiumai/pr-agent:bitbucket_server_webhook --target bitbucket_server_webhook -f docker/Dockerfile
docker push codiumai/pr-agent:bitbucket_server_webhook # Push to your Docker repository
```
Navigate to `Projects` or `Repositories`, `Settings`, `Webhooks`, `Create Webhook`.
Fill the name and URL, Authentication None select the Pull Request Opened checkbox to receive that event as webhook.
The URL should end with `/webhook`, for example: https://domain.com/webhook

## Overview - PR Compression Strategy
# PR Compression Strategy
There are two scenarios:
1. The PR is small enough to fit in a single prompt (including system and user prompt)
2. The PR is too large to fit in a single prompt (including system and user prompt)
For both scenarios, we first use the following strategy
#### Repo language prioritization strategy
We prioritize the languages of the repo based on the following criteria:
1. Exclude binary files and non code files (e.g. images, pdfs, etc)
2. Given the main languages used in the repo
3. We sort the PR files by the most common languages in the repo (in descending order):
2. We sort the PR files by the most common languages in the repo (in descending order):
* ```[[file.py, file2.py],[file3.js, file4.jsx],[readme.md]]```
### Small PR
## Small PR
In this case, we can fit the entire PR in a single prompt:
1. Exclude binary files and non code files (e.g. images, pdfs, etc)
2. We Expand the surrounding context of each patch to 3 lines above and below the patch
## Large PR
### Large PR
#### Motivation
### Motivation
Pull Requests can be very long and contain a lot of information with varying degree of relevance to the pr-agent.
We want to be able to pack as much information as possible in a single LMM prompt, while keeping the information relevant to the pr-agent.
#### Compression strategy
We prioritize additions over deletions:
* Combine all deleted files into a single list (`deleted files`)
* File patches are a list of hunks, remove all hunks of type deletion-only from the hunks in the file patch
#### Adaptive and token-aware file patch fitting
- Combine all deleted files into a single list (`deleted files`)
- File patches are a list of hunks, remove all hunks of type deletion-only from the hunks in the file patch
#### Adaptive and token-aware file patch fitting
We use [tiktoken](https://github.com/openai/tiktoken) to tokenize the patches after the modifications described above, and we use the following strategy to fit the patches into the prompt:
1. Within each language we sort the files by the number of tokens in the file (in descending order):
* ```[[file2.py, file.py],[file4.jsx, file3.js],[readme.md]]```
* ```[[file2.py, file.py],[file4.jsx, file3.js],[readme.md]]```
2. Iterate through the patches in the order described above
3. Add the patches to the prompt until the prompt reaches a certain buffer from the max token length
4. If there are still patches left, add the remaining patches as a list called `other modified files` to the prompt until the prompt reaches the max token length (hard stop), skip the rest of the patches.
5. If we haven't reached the max token length, add the `deleted files` to the prompt until the prompt reaches the max token length (hard stop), skip the rest of the patches.
2. Add the patches to the prompt until the prompt reaches a certain buffer from the max token length
3. If there are still patches left, add the remaining patches as a list called `other modified files` to the prompt until the prompt reaches the max token length (hard stop), skip the rest of the patches.
4. If we haven't reached the max token length, add the `deleted files` to the prompt until the prompt reaches the max token length (hard stop), skip the rest of the patches.

Note that this is a promotional bot, suitable only for initial experimentation.
It does not have 'edit' access to your repo, for example, so it cannot update the PR description or add labels (`@CodiumAI-Agent /describe` will publish PR description as a comment). In addition, the bot cannot be used on private repositories, as it does not have access to the files there.
To set up your own PR-Agent, see the [Installation](#installation) section below.
Note that when you set your own PR-Agent or use CodiumAI hosted PR-Agent, there is no need to mention `@CodiumAI-Agent ...`. Instead, directly start with the command, e.g., `/ask ...`.

## Qodo Merge 💎
## Installation
[Qodo Merge](https://www.qodo.ai/pricing/) is a hosted version of PR-Agent, provided by Qodo. It is available for a monthly fee, and provides the following benefits:
To get started with PR-Agent quickly, you first need to acquire two tokens:
1. **Fully managed** - We take care of everything for you - hosting, models, regular updates, and more. Installation is as simple as signing up and adding the Qodo Merge app to your GitHub/GitLab/BitBucket repo.
2. **Improved privacy** - No data will be stored or used to train models. Qodo Merge will employ zero data retention, and will use an OpenAI account with zero data retention.
3. **Improved support** - Qodo Merge users will receive priority support, and will be able to request new features and capabilities.
4. **Extra features** - In addition to the benefits listed above, Qodo Merge will emphasize more customization, and the usage of static code analysis, in addition to LLM logic, to improve results.
See [here](https://qodo-merge-docs.qodo.ai/overview/pr_agent_pro/) for a list of features available in Qodo Merge.
1. An OpenAI key from [here](https://platform.openai.com/), with access to GPT-4.
2. A GitHub personal access token (classic) with the repo scope.
There are several ways to use PR-Agent:
- [Method 1: Use Docker image (no installation required)](INSTALL.md#method-1-use-docker-image-no-installation-required)
- [Method 2: Run from source](INSTALL.md#method-2-run-from-source)
- [Method 3: Run as a GitHub Action](INSTALL.md#method-3-run-as-a-github-action)
- [Method 4: Run as a polling server](INSTALL.md#method-4-run-as-a-polling-server)
- Request reviews by tagging your GitHub user on a PR
- [Method 5: Run as a GitHub App](INSTALL.md#method-5-run-as-a-github-app)
- Allowing you to automate the review process on your private or public repositories
- [Method 6: Deploy as a Lambda Function](INSTALL.md#method-6---deploy-as-a-lambda-function)
- [Method 7: AWS CodeCommit](INSTALL.md#method-7---aws-codecommit-setup)
- [Method 8: Run a GitLab webhook server](INSTALL.md#method-8---run-a-gitlab-webhook-server)
- [Method 9: Run as a Bitbucket Pipeline](INSTALL.md#method-9-run-as-a-bitbucket-pipeline)

## Why use PR-Agent?
A reasonable question that can be asked is: `"Why use PR-Agent? What makes it stand out from existing tools?"`
A reasonable question that can be asked is: `"Why use PR-Agent? What make it stand out from existing tools?"`
Here are some advantages of PR-Agent:
- We emphasize **real-life practical usage**. Each tool (review, improve, ask, ...) has a single LLM call, no more. We feel that this is critical for realistic team usage - obtaining an answer quickly (~30 seconds) and affordably.
- Our [PR Compression strategy](https://qodo-merge-docs.qodo.ai/core-abilities/#pr-compression-strategy) is a core ability that enables to effectively tackle both short and long PRs.

- Our [PR Compression strategy](./PR_COMPRESSION.md) is a core ability that enables to effectively tackle both short and long PRs.
- Our JSON prompting strategy enables to have **modular, customizable tools**. For example, the '/review' tool categories can be controlled via the [configuration](pr_agent/settings/configuration.toml) file. Adding additional categories is easy and accessible.
- We support **multiple git providers** (GitHub, GitLab, BitBucket), **multiple ways** to use the tool (CLI, GitHub Action, GitHub App, Docker, ...), and **multiple models** (GPT, Claude, Deepseek, ...)
- We support **multiple git providers** (GitHub, Gitlab, Bitbucket, CodeCommit), **multiple ways** to use the tool (CLI, GitHub Action, GitHub App, Docker, ...), and **multiple models** (GPT-4, GPT-3.5, Anthropic, Cohere, Llama2).
- We are open-source, and welcome contributions from the community.
## Data privacy
### Self-hosted PR-Agent
## Roadmap
- If you host PR-Agent with your OpenAI API key, it is between you and OpenAI. You can read their API data privacy policy here:

- [Working with large PRs](#working-with-large-prs)
- [Appendix - additional configurations walkthrough](#appendix---additional-configurations-walkthrough)
### Introduction
After [installation](/INSTALL.md), there are three basic ways to invoke CodiumAI PR-Agent:
1. Locally running a CLI command
2. Online usage - by [commenting](https://github.com/Codium-ai/pr-agent/pull/229#issuecomment-1695021901) on a PR
3. Enabling PR-Agent tools to run automatically when a new PR is opened
Specifically, CLI commands can be issued by invoking a pre-built [docker image](/INSTALL.md#running-from-source), or by invoking a [locally cloned repo](INSTALL.md#method-2-run-from-source).
For online usage, you will need to setup either a [GitHub App](INSTALL.md#method-5-run-as-a-github-app), or a [GitHub Action](INSTALL.md#method-3-run-as-a-github-action).
GitHub App and GitHub Action also enable to run PR-Agent specific tool automatically when a new PR is opened.
#### The configuration file
The different tools and sub-tools used by CodiumAI PR-Agent are adjustable via the **[configuration file](pr_agent/settings/configuration.toml)**.
In addition to general configuration options, each tool has its own configurations. For example, the `review` tool will use parameters from the [pr_reviewer](/pr_agent/settings/configuration.toml#L16) section in the configuration file.
The [Tools Guide](./docs/TOOLS_GUIDE.md) provides a detailed description of the different tools and their configurations.
#### Ignoring files from analysis
In some cases, you may want to exclude specific files or directories from the analysis performed by CodiumAI PR-Agent. This can be useful, for example, when you have files that are generated automatically or files that shouldn't be reviewed, like vendored code.
To ignore files or directories, edit the **[ignore.toml](/pr_agent/settings/ignore.toml)** configuration file. This setting also exposes the following environment variables:
- `IGNORE.GLOB`
- `IGNORE.REGEX`
For example, to ignore python files in a PR with online usage, comment on a PR:
`/review --ignore.glob=['*.py']`
To ignore python files in all PRs, set in a configuration file:
```
[ignore]
glob = ['*.py']
```
#### git provider
The [git_provider](pr_agent/settings/configuration.toml#L4) field in the configuration file determines the GIT provider that will be used by PR-Agent. Currently, the following providers are supported:
`
"github", "gitlab", "azure", "codecommit", "local", "gerrit"
`
[//]: # (** online usage:**)
[//]: # (Options that are available in the configuration file can be specified at run time when calling actions. Two examples:)
[//]: # (```)
[//]: # (- /review --pr_reviewer.extra_instructions="focus on the file: ...")
[//]: # (- /describe --pr_description.add_original_user_description=false -pr_description.extra_instructions="make sure to mention: ...")
[//]: # (```)
### Working from a local repo (CLI)
When running from your local repo (CLI), your local configuration file will be used.
Examples of invoking the different tools via the CLI:
- **Review**: `python -m pr_agent.cli --pr_url=<pr_url> review`
- **Describe**: `python -m pr_agent.cli --pr_url=<pr_url> describe`
- **Improve**: `python -m pr_agent.cli --pr_url=<pr_url> improve`
- **Ask**: `python -m pr_agent.cli --pr_url=<pr_url> ask "Write me a poem about this PR"`
- **Reflect**: `python -m pr_agent.cli --pr_url=<pr_url> reflect`
- **Update Changelog**: `python -m pr_agent.cli --pr_url=<pr_url> update_changelog`
`<pr_url>` is the url of the relevant PR (for example: https://github.com/Codium-ai/pr-agent/pull/50).
**Notes:**
(1) in addition to editing your local configuration file, you can also change any configuration value by adding it to the command line:
```
python -m pr_agent.cli --pr_url=<pr_url> /review --pr_reviewer.extra_instructions="focus on the file: ..."
```
(2) You can print results locally, without publishing them, by setting in `configuration.toml`:
```
[config]
publish_output=true
verbosity_level=2
```
This is useful for debugging or experimenting with different tools.
### Online usage
Online usage means invoking PR-Agent tools by [comments](https://github.com/Codium-ai/pr-agent/pull/229#issuecomment-1695021901) on a PR.
Commands for invoking the different tools via comments:
- **Review**: `/review`
- **Describe**: `/describe`
- **Improve**: `/improve`
- **Ask**: `/ask "..."`
- **Reflect**: `/reflect`
- **Update Changelog**: `/update_changelog`
To edit a specific configuration value, just add `--config_path=<value>` to any command.
For example, if you want to edit the `review` tool configurations, you can run:
```
/review --pr_reviewer.extra_instructions="..." --pr_reviewer.require_score_review=false
```
Any configuration value in [configuration file](pr_agent/settings/configuration.toml) file can be similarly edited. Comment `/config` to see the list of available configurations.
### Working with GitHub App
When running PR-Agent from GitHub App, the default [configuration file](pr_agent/settings/configuration.toml) from a pre-built docker will be initially loaded.
By uploading a local `.pr_agent.toml` file to the root of the repo's main branch, you can edit and customize any configuration parameter. Note that you need to upload `.pr_agent.toml` prior to creating a PR, in order for the configuration to take effect.
For example, if you set in `.pr_agent.toml`:
```
[pr_reviewer]
num_code_suggestions=1
```
Then you will overwrite the default number of code suggestions to 1.
#### GitHub app automatic tools
The [github_app](pr_agent/settings/configuration.toml#L76) section defines GitHub app-specific configurations.
In this section you can define configurations to control the conditions for which tools will **run automatically**.
##### GitHub app automatic tools for PR actions
The GitHub app can respond to the following actions on a PR:
1. `opened` - Opening a new PR
2. `reopened` - Reopening a closed PR
3. `ready_for_review` - Moving a PR from Draft to Open
4. `review_requested` - Specifically requesting review (in the PR reviewers list) from the `github-actions[bot]` user
The configuration parameter `handle_pr_actions` defines the list of actions for which the GitHub app will trigger the PR-Agent.
The configuration parameter `pr_commands` defines the list of tools that will be **run automatically** when one of the above actions happens (e.g., a new PR is opened):
```
[github_app]
handle_pr_actions = ['opened', 'reopened', 'ready_for_review', 'review_requested']
pr_commands = [
"/describe --pr_description.add_original_user_description=true --pr_description.keep_original_user_title=true",
"/auto_review",
]
```
This means that when a new PR is opened/reopened or marked as ready for review, PR-Agent will run the `describe` and `auto_review` tools.
For the describe tool, the `add_original_user_description` and `keep_original_user_title` parameters will be set to true.
You can override the default tool parameters by uploading a local configuration file called `.pr_agent.toml` to the root of your repo.
For example, if your local `.pr_agent.toml` file contains:
```
[pr_description]
add_original_user_description = false
keep_original_user_title = false
```
When a new PR is opened, PR-Agent will run the `describe` tool with the above parameters.
To cancel the automatic run of all the tools, set:
```
[github_app]
handle_pr_actions = []
```
##### GitHub app automatic tools for new code (PR push)
In addition to running automatic tools when a PR is opened, the GitHub app can also respond to new code that is pushed to an open PR.
The configuration toggle `handle_push_trigger` can be used to enable this feature.
The configuration parameter `push_commands` defines the list of tools that will be **run automatically** when new code is pushed to the PR.
```
[github_app]
handle_push_trigger = true
push_commands = [
"/describe --pr_description.add_original_user_description=true --pr_description.keep_original_user_title=true",
"/auto_review -i --pr_reviewer.remove_previous_review_comment=true",
]
```
This means that when new code is pushed to the PR, the PR-Agent will run the `describe` and incremental `auto_review` tools.
For the describe tool, the `add_original_user_description` and `keep_original_user_title` parameters will be set to true.
For the `auto_review` tool, it will run in incremental mode, and the `remove_previous_review_comment` parameter will be set to true.
Much like the configurations for `pr_commands`, you can override the default tool parameters by uploading a local configuration file to the root of your repo.
#### Editing the prompts
The prompts for the various PR-Agent tools are defined in the `pr_agent/settings` folder.
In practice, the prompts are loaded and stored as a standard setting object.
Hence, editing them is similar to editing any other configuration value - just place the relevant key in `.pr_agent.toml`file, and override the default value.
For example, if you want to edit the prompts of the [describe](./pr_agent/settings/pr_description_prompts.toml) tool, you can add the following to your `.pr_agent.toml` file:
```
[pr_description_prompt]
system="""
...
"""
user="""
...
"""
```
Note that the new prompt will need to generate an output compatible with the relevant [post-process function](./pr_agent/tools/pr_description.py#L137).
### Working with GitHub Action
You can configure settings in GitHub action by adding environment variables under the env section in `.github/workflows/pr_agent.yml` file.
Specifically, start by setting the following environment variables:
```yaml
env:
OPENAI_KEY: ${{ secrets.OPENAI_KEY }} # Make sure to add your OpenAI key to your repo secrets
GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }} # Make sure to add your GitHub token to your repo secrets
github_action.auto_review: "true" # enable\disable auto review
github_action.auto_describe: "true" # enable\disable auto describe
github_action.auto_improve: "false" # enable\disable auto improve
```
`github_action.auto_review`, `github_action.auto_describe` and `github_action.auto_improve` are used to enable/disable automatic tools that run when a new PR is opened.
If not set, the default option is that only the `review` tool will run automatically when a new PR is opened.
Note that you can give additional config parameters by adding environment variables to `.github/workflows/pr_agent.yml`, or by using a `.pr_agent.toml` file in the root of your repo, similar to the GitHub App usage.
For example, you can set an environment variable: `pr_description.add_original_user_description=false`, or add a `.pr_agent.toml` file with the following content:
```
[pr_description]
add_original_user_description = false
```
### Working with BitBucket Self-Hosted App
Similar to GitHub app, when running PR-Agent from BitBucket App, the default [configuration file](pr_agent/settings/configuration.toml) from a pre-built docker will be initially loaded.
By uploading a local `.pr_agent.toml` file to the root of the repo's main branch, you can edit and customize any configuration parameter. Note that you need to upload `.pr_agent.toml` prior to creating a PR, in order for the configuration to take effect.
For example, if your local `.pr_agent.toml` file contains:
```
[pr_reviewer]
inline_code_comments = true
```
Each time you invoke a `/review` tool, it will use inline code comments.
#### BitBucket Self-Hosted App automatic tools
You can configure in your local `.pr_agent.toml` file which tools will **run automatically** when a new PR is opened.
Specifically, set the following values:
```yaml
[bitbucket_app]
auto_review = true # set as config var in .pr_agent.toml
auto_describe = true # set as config var in .pr_agent.toml
auto_improve = true # set as config var in .pr_agent.toml
```
`bitbucket_app.auto_review`, `bitbucket_app.auto_describe` and `bitbucket_app.auto_improve` are used to enable/disable automatic tools.
If not set, the default option is that only the `review` tool will run automatically when a new PR is opened.
Note that due to limitations of the bitbucket platform, the `auto_describe` tool will be able to publish a PR description only as a comment.
In addition, some subsections like `PR changes walkthrough` will not appear, since they require the usage of collapsible sections, which are not supported by bitbucket.
### Changing a model
See [here](pr_agent/algo/__init__.py) for the list of available models.
To use a different model than the default (GPT-4), you need to edit [configuration file](pr_agent/settings/configuration.toml#L2).
For models and environments not from OPENAI, you might need to provide additional keys and other parameters. See below for instructions.
#### Azure
To use Azure, set in your `.secrets.toml` (working from CLI), or in the GitHub `Settings > Secrets and variables` (working from GitHub App or GitHub Action):
```
api_key = "" # your azure api key
api_type = "azure"
api_version = '2023-05-15' # Check Azure documentation for the current API version
api_base = "" # The base URL for your Azure OpenAI resource. e.g. "https://<your resource name>.openai.azure.com"
openai.deployment_id = "" # The deployment name you chose when you deployed the engine
```
and set in your configuration file:
```
[config]
model="" # the OpenAI model you've deployed on Azure (e.g. gpt-3.5-turbo)
```
#### Huggingface
**Local**
You can run Huggingface models locally through either [VLLM](https://docs.litellm.ai/docs/providers/vllm) or [Ollama](https://docs.litellm.ai/docs/providers/ollama)
E.g. to use a new Huggingface model locally via Ollama, set:
```
[__init__.py]
MAX_TOKENS = {
"model-name-on-ollama": <max_tokens>
}
e.g.
MAX_TOKENS={
...,
"ollama/llama2": 4096
}
[config] # in configuration.toml
model = "ollama/llama2"
[ollama] # in .secrets.toml
api_base = ... # the base url for your huggingface inference endpoint
# e.g. if running Ollama locally, you may use:
api_base = "http://localhost:11434/"
```
**Inference Endpoints**
To use a new model with Huggingface Inference Endpoints, for example, set:
```
[__init__.py]
MAX_TOKENS = {
"model-name-on-huggingface": <max_tokens>
}
e.g.
MAX_TOKENS={
...,
"meta-llama/Llama-2-7b-chat-hf": 4096
}
[config] # in configuration.toml
model = "huggingface/meta-llama/Llama-2-7b-chat-hf"
[huggingface] # in .secrets.toml
key = ... # your huggingface api key
api_base = ... # the base url for your huggingface inference endpoint
```
(you can obtain a Llama2 key from [here](https://replicate.com/replicate/llama-2-70b-chat/api))
#### Replicate
To use Llama2 model with Replicate, for example, set:
```
[config] # in configuration.toml
model = "replicate/llama-2-70b-chat:2c1608e18606fad2812020dc541930f2d0495ce32eee50074220b87300bc16e1"
[replicate] # in .secrets.toml
key = ...
```
(you can obtain a Llama2 key from [here](https://replicate.com/replicate/llama-2-70b-chat/api))
Also review the [AiHandler](pr_agent/algo/ai_handler.py) file for instruction how to set keys for other models.
#### Vertex AI
To use Google's Vertex AI platform and its associated models (chat-bison/codechat-bison) set:
```
[config] # in configuration.toml
model = "vertex_ai/codechat-bison"
fallback_models="vertex_ai/codechat-bison"
[vertexai] # in .secrets.toml
vertex_project = "my-google-cloud-project"
vertex_location = ""
```
Your [application default credentials](https://cloud.google.com/docs/authentication/application-default-credentials) will be used for authentication so there is no need to set explicit credentials in most environments.
If you do want to set explicit credentials then you can use the `GOOGLE_APPLICATION_CREDENTIALS` environment variable set to a path to a json credentials file.
#### Amazon Bedrock
To use Amazon Bedrock and its foundational models, add the below configuration:
```
[config] # in configuration.toml
model = "anthropic.claude-v2"
fallback_models="anthropic.claude-instant-v1"
[aws] # in .secrets.toml
bedrock_region = "us-east-1"
```
Note that you have to add access to foundational models before using them. Please refer to [this document](https://docs.aws.amazon.com/bedrock/latest/userguide/setting-up.html) for more details.
AWS session is automatically authenticated from your environment, but you can also explicitly set `AWS_ACCESS_KEY_ID` and `AWS_SECRET_ACCESS_KEY` environment variables.
### Working with large PRs
The default mode of CodiumAI is to have a single call per tool, using GPT-4, which has a token limit of 8000 tokens.
This mode provide a very good speed-quality-cost tradeoff, and can handle most PRs successfully.
When the PR is above the token limit, it employs a [PR Compression strategy](./PR_COMPRESSION.md).
However, for very large PRs, or in case you want to emphasize quality over speed and cost, there are 2 possible solutions:
1) [Use a model](#changing-a-model) with larger context, like GPT-32K, or claude-100K. This solution will be applicable for all the tools.
2) For the `/improve` tool, there is an ['extended' mode](./docs/IMPROVE.md) (`/improve --extended`),
which divides the PR to chunks, and process each chunk separately. With this mode, regardless of the model, no compression will be done (but for large PRs, multiple model calls may occur)
### Appendix - additional configurations walkthrough
#### Extra instructions
All PR-Agent tools have a parameter called `extra_instructions`, that enables to add free-text extra instructions. Example usage:
```
/update_changelog --pr_update_changelog.extra_instructions="Make sure to update also the version ..."
```
#### Patch Extra Lines
By default, around any change in your PR, git patch provides 3 lines of context above and below the change.
```
@@ -12,5 +12,5 @@ def func1():
code line that already existed in the file...
code line that already existed in the file...

-code line that was removed in the PR
+new code line added in the PR
code line that already existed in the file...
code line that already existed in the file...
code line that already existed in the file...
```
For the `review`, `describe`, `ask` and `add_docs` tools, if the token budget allows, PR-Agent tries to increase the number of lines of context, via the parameter:
```
[config]
patch_extra_lines=3
```
Increasing this number provides more context to the model, but will also increase the token budget.
If the PR is too large (see [PR Compression strategy](./PR_COMPRESSION.md)), PR-Agent automatically sets this number to 0, using the original git patch.
#### Azure DevOps provider
To use Azure DevOps provider use the following settings in configuration.toml:
```
[config]
git_provider="azure"
use_repo_settings_file=false
```
And use the following settings (you have to replace the values) in .secrets.toml:
```
[azure_devops]
org = "https://dev.azure.com/YOUR_ORGANIZATION/"
pat = "YOUR_PAT_TOKEN"
```

# Describe Tool
The `describe` tool scans the PR code changes, and automatically generates PR description - title, type, summary, walkthrough and labels.
It can be invoked manually by commenting on any PR:
```
/describe
```
For example:
<kbd><img src=https://codium.ai/images/pr_agent/describe_comment.png width="768"></kbd>
<kbd><img src=https://codium.ai/images/pr_agent/describe.png width="768"></kbd>
The `describe` tool can also be triggered automatically every time a new PR is opened. See examples for automatic triggers for [GitHub App](https://github.com/Codium-ai/pr-agent/blob/main/Usage.md#github-app-automatic-tools) and [GitHub Action](https://github.com/Codium-ai/pr-agent/blob/main/Usage.md#working-with-github-action)
### Configuration options
Under the section 'pr_description', the [configuration file](./../pr_agent/settings/configuration.toml#L28) contains options to customize the 'describe' tool:
- `publish_labels`: if set to true, the tool will publish the labels to the PR. Default is true.
- `publish_description_as_comment`: if set to true, the tool will publish the description as a comment to the PR. If false, it will overwrite the origianl description. Default is false.
- `add_original_user_description`: if set to true, the tool will add the original user description to the generated description. Default is false.
- `keep_original_user_title`: if set to true, the tool will keep the original PR title, and won't change it. Default is false.
- `extra_instructions`: Optional extra instructions to the tool. For example: "focus on the changes in the file X. Ignore change in ...".
- To enable `custom labels`, apply the configuration changes described [here](./GENERATE_CUSTOM_LABELS.md#configuration-changes)
- `enable_pr_type`: if set to false, it will not show the `PR type` as a text value in the description content. Default is true.
- `final_update_message`: if set to true, it will add a comment message [`PR Description updated to latest commit...`](https://github.com/Codium-ai/pr-agent/pull/499#issuecomment-1837412176) after finishing calling `/describe`. Default is true.
- `enable_semantic_files_types`: if set to true, "PR changes walkthrough" section will be generated. Default is true.
### Markers template
markers enable to easily integrate user's content and auto-generated content, with a template-like mechanism.
For example, if the PR original description was:
```
User content...
## PR Description:
pr_agent:summary
## PR Walkthrough:
pr_agent:walkthrough
```
The marker `pr_agent:summary` will be replaced with the PR summary, and `pr_agent:walkthrough` will be replaced with the PR walkthrough.
##### Example:
```
env:
pr_description.use_description_markers: 'true'
```

==>
<kbd><img src=https://codium.ai/images/pr_agent/describe_markers_after.png width="768"></kbd>
##### Configuration params:
- `use_description_markers`: if set to true, the tool will use markers template. It replaces every marker of the form `pr_agent:marker_name` with the relevant content. Default is false.
- `include_generated_by_header`: if set to true, the tool will add a dedicated header: 'Generated by PR Agent at ...' to any automatic content. Default is true.

# Generate Custom Labels
The `generate_labels` tool scans the PR code changes, and given a list of labels and their descriptions, it automatically suggests labels that match the PR code changes.
It can be invoked manually by commenting on any PR:
```
/generate_labels
```
For example:
If we wish to add detect changes to SQL queries in a given PR, we can add the following custom label along with its description:
<kbd><img src=https://codium.ai/images/pr_agent/custom_labels_list.png width="768"></kbd>
When running the `generate_labels` tool on a PR that includes changes in SQL queries, it will automatically suggest the custom label:
<kbd><img src=https://codium.ai/images/pr_agent/custom_label_published.png width="768"></kbd>
### How to enable custom labels
Note that in addition to the dedicated tool `generate_labels`, the custom labels will also be used by the `review` and `describe` tools.
#### CLI
To enable custom labels, you need to apply the [configuration changes](#configuration-changes) to the [custom_labels file](./../pr_agent/settings/custom_labels.toml):
#### GitHub Action and GitHub App
To enable custom labels, you need to apply the [configuration changes](#configuration-changes) to the local `.pr_agent.toml` file in you repository.
#### Configuration changes
- Change `enable_custom_labels` to True: This will turn off the default labels and enable the custom labels provided in the custom_labels.toml file.
- Add the custom labels. It should be formatted as follows:
```
[config]
enable_custom_labels=true
[custom_labels."Custom Label Name"]
description = "Description of when AI should suggest this label"
[custom_labels."Custom Label 2"]
description = "Description of when AI should suggest this label 2"
```

# Improve Tool
The `improve` tool scans the PR code changes, and automatically generates committable suggestions for improving the PR code.
It can be invoked manually by commenting on any PR:
```
/improve
```
For example:
<kbd><img src=https://codium.ai/images/pr_agent/improve_comment.png width="768"></kbd>
<kbd><img src=https://codium.ai/images/pr_agent/improve.png width="768"></kbd>
The `improve` tool can also be triggered automatically every time a new PR is opened. See examples for automatic triggers for [GitHub App](https://github.com/Codium-ai/pr-agent/blob/main/Usage.md#github-app-automatic-tools) and [GitHub Action](https://github.com/Codium-ai/pr-agent/blob/main/Usage.md#working-with-github-action)
An extended mode, which does not involve PR Compression and provides more comprehensive suggestions, can be invoked by commenting on any PR:
```
/improve --extended
```
Note that the extended mode divides the PR code changes into chunks, up to the token limits, where each chunk is handled separately (multiple calls to GPT-4).
Hence, the total number of suggestions is proportional to the number of chunks, i.e., the size of the PR.
### Configuration options
Under the section 'pr_code_suggestions', the [configuration file](./../pr_agent/settings/configuration.toml#L40) contains options to customize the 'improve' tool:
- `num_code_suggestions`: number of code suggestions provided by the 'improve' tool. Default is 4.
- `extra_instructions`: Optional extra instructions to the tool. For example: "focus on the changes in the file X. Ignore change in ...".
- `rank_suggestions`: if set to true, the tool will rank the suggestions, based on importance. Default is false.
#### params for '/improve --extended' mode
- `num_code_suggestions_per_chunk`: number of code suggestions provided by the 'improve' tool, per chunk. Default is 8.
- `rank_extended_suggestions`: if set to true, the tool will rank the suggestions, based on importance. Default is true.
- `max_number_of_calls`: maximum number of chunks. Default is 5.
- `final_clip_factor`: factor to remove suggestions with low confidence. Default is 0.9.
#### summarize mode
- `summarize`: if set to true, the tool will present the code suggestions in a compact way. Default is false.
In this mode, instead of presenting committable suggestions, the different suggestions will be combined into a single compact comment, with significantly smaller PR footprint.
For example:
`/improve --pr_code_suggestions.summarize=true`
<kbd><img src=https://codium.ai/images/pr_agent/improved_summerize_open.png width="768"></kbd>
___
### A note on code suggestions quality
- While the current AI for code is getting better and better (GPT-4), it's not flawless. Not all the suggestions will be perfect, and a user should not accept all of them automatically.
- Suggestions are not meant to be [simplistic](./../pr_agent/settings/pr_code_suggestions_prompts.toml#L34). Instead, they aim to give deep feedback and raise questions, ideas and thoughts to the user, who can then use his judgment, experience, and understanding of the code base.
- Recommended to use the 'extra_instructions' field to guide the model to suggestions that are more relevant to the specific needs of the project.
- Best quality will be obtained by using 'improve --extended' mode.

- `require_score_review`: if set to true, the tool will add a section that scores the PR. Default is false.
- `require_tests_review`: if set to true, the tool will add a section that checks if the PR contains tests. Default is true.
- `require_security_review`: if set to true, the tool will add a section that checks if the PR contains security issues. Default is true.
- `require_estimate_effort_to_review`: if set to true, the tool will add a section that estimates thed effort needed to review the PR. Default is true.
#### general options
- `num_code_suggestions`: number of code suggestions provided by the 'review' tool. Default is 4.
- `inline_code_comments`: if set to true, the tool will publish the code suggestions as comments on the code diff. Default is false.
- `automatic_review`: if set to false, no automatic reviews will be done. Default is true.
- `remove_previous_review_comment`: if set to true, the tool will remove the previous review comment before adding a new one. Default is false.
- `persistent_comment`: if set to true, the review comment will be persistent, meaning that every new review request will edit the previous one. Default is true.
- `extra_instructions`: Optional extra instructions to the tool. For example: "focus on the changes in the file X. Ignore change in ...".
#### review labels
- `enable_review_labels_security`: if set to true, the tool will publish a 'possible security issue' label if it detects a security issue. Default is true.
- `enable_review_labels_effort`: if set to true, the tool will publish a 'Review effort [1-5]: x' label. Default is false.
- To enable `custom labels`, apply the configuration changes described [here](./GENERATE_CUSTOM_LABELS.md#configuration-changes)
#### Incremental Mode
For an incremental review, which only considers changes since the last PR-Agent review, this can be useful when working on the PR in an iterative manner, and you want to focus on the changes since the last review instead of reviewing the entire PR again, the following command can be used:
```
/review -i
```
Note that the incremental mode is only available for GitHub.
<kbd><img src=https://codium.ai/images/pr_agent/incremental_review.png width="768"></kbd>
Under the section 'pr_reviewer', the [configuration file](./../pr_agent/settings/configuration.toml#L16) contains options to customize the 'review -i' tool.
These configurations can be used to control the rate at which the incremental review tool will create new review comments when invoked automatically, to prevent making too much noise in the PR.
- `minimal_commits_for_incremental_review`: Minimal number of commits since the last review that are required to create incremental review.
If there are less than the specified number of commits since the last review, the tool will not perform any action.
Default is 0 - the tool will always run, no matter how many commits since the last review.
- `minimal_minutes_for_incremental_review`: Minimal number of minutes that need to pass since the last reviewed commit to create incremental review.
If less that the specified number of minutes have passed between the last reviewed commit and running this command, the tool will not perform any action.
Default is 0 - the tool will always run, no matter how much time have passed since the last reviewed commit.
- `require_all_thresholds_for_incremental_review`: If set to true, all the previous thresholds must be met for incremental review to run. If false, only one is enough to run the tool.
For example, if `minimal_commits_for_incremental_review=2` and `minimal_minutes_for_incremental_review=2`, and we have 3 commits since the last review, but the last reviewed commit is from 1 minute ago:
When `require_all_thresholds_for_incremental_review=true` the incremental review __will not__ run, because only 1 out of 2 conditions were met (we have enough commits but the last review is too recent),
but when `require_all_thresholds_for_incremental_review=false` the incremental review __will__ run, because one condition is enough (we have 3 commits which is more than the configured 2).
Default is false - the tool will run as long as at least once conditions is met.
#### PR Reflection
By invoking:
```
/reflect_and_review
```
The tool will first ask the author questions about the PR, and will guide the review based on his answers.
<kbd><img src=https://codium.ai/images/pr_agent/reflection_questions.png width="768"></kbd>
<kbd><img src=https://codium.ai/images/pr_agent/reflection_answers.png width="768"></kbd>
<kbd><img src=https://codium.ai/images/pr_agent/reflection_insights.png width="768"></kbd>
#### A note on code suggestions quality
- With current level of AI for code (GPT-4), mistakes can happen. Not all the suggestions will be perfect, and a user should not accept all of them automatically.
- Suggestions are not meant to be [simplistic](./../pr_agent/settings/pr_reviewer_prompts.toml#L29). Instead, they aim to give deep feedback and raise questions, ideas and thoughts to the user, who can then use his judgment, experience, and understanding of the code base.
- Recommended to use the 'extra_instructions' field to guide the model to suggestions that are more relevant to the specific needs of the project.
- Unlike the 'review' feature, which does a lot of things, the ['improve --extended'](./IMPROVE.md) feature is dedicated only to suggestions, and usually gives better results.

## Overview
# Similar Issue Tool
The similar issue tool retrieves the most similar issues to the current issue.
It can be invoked manually by commenting on any PR:
```
/similar_issue
```
For example:
## Example usage
![similar_issue_original_issue](https://codium.ai/images/pr_agent/similar_issue_original_issue.png){width=768}
![similar_issue_comment](https://codium.ai/images/pr_agent/similar_issue_comment.png){width=768}
![similar_issue](https://codium.ai/images/pr_agent/similar_issue.png){width=768}

<kbd><img src=https://codium.ai/images/pr_agent/similar_issue.png width="768"></kbd>
Note that to perform retrieval, the `similar_issue` tool indexes all the repo previous issues (once).
### Selecting a Vector Database
Configure your preferred database by changing the `pr_similar_issue` parameter in `configuration.toml` file.
#### Available Options
Choose from the following Vector Databases:
1. LanceDB
2. Pinecone
#### Pinecone Configuration

### PR chat
The PR-Chat feature allows to freely chat with your PR code, within your GitHub environment.
It will seamlessly use the PR as context to your chat session, and provide AI-powered feedback.
To enable private chat, simply install the Qodo Merge Chrome extension. After installation, each PR's file-changed tab will include a chat box, where you may ask questions about your code.
This chat session is **private**, and won't be visible to other users.
All open-source repositories are supported.
For private repositories, you will also need to install Qodo Merge. After installation, make sure to open at least one new PR to fully register your organization. Once done, you can chat with both new and existing PRs across all installed repositories.
#### Context-aware PR chat
Qodo Merge constructs a comprehensive context for each pull request, incorporating the PR description, commit messages, and code changes with extended dynamic context. This contextual information, along with additional PR-related data, forms the foundation for an AI-powered chat session. The agent then leverages this rich context to provide intelligent, tailored responses to user inquiries about the pull request.

# Auto Best Practices 💎
`Supported Git Platforms: GitHub`
## Overview
![Auto best practice suggestion graph](https://www.qodo.ai/images/pr_agent/auto_best_practices_graph.png){width=684}
> Note - enabling a [Wiki](https://qodo-merge-docs.qodo.ai/usage-guide/enabling_a_wiki/) is required for this feature.
### Finding Code Problems - Exploration Phase
The `improve` tool identifies potential issues, problems and bugs in Pull Request (PR) code changes.
Rather than focusing on minor issues like code style or formatting, the tool intelligently analyzes code to detect meaningful problems.
The analysis intentionally takes a flexible, _exploratory_ approach to identify meaningful potential issues, allowing the tool to surface relevant code suggestions without being constrained by predefined categories.
### Tracking Implemented Suggestions
Qodo Merge features a novel [tracking system](https://qodo-merge-docs.qodo.ai/tools/improve/#suggestion-tracking) that automatically detects when PR authors implement AI-generated code suggestions.
All accepted suggestions are aggregated in a repository-specific wiki page called [`.pr_agent_accepted_suggestions`](https://github.com/qodo-ai/pr-agent/wiki/.pr_agent_accepted_suggestions)
### Learning and Applying Auto Best Practices
Monthly, Qodo Merge analyzes the collection of accepted suggestions to generate repository-specific best practices, stored in [`.pr_agent_auto_best_practices`](https://github.com/qodo-ai/pr-agent/wiki/.pr_agent_auto_best_practices) wiki file.
These best practices reflect recurring patterns in accepted code improvements.
The `improve` tool will incorporate these best practices as an additional analysis layer, checking PR code changes against known patterns of previously accepted improvements.
This creates a two-phase analysis:
1. Open exploration for general code issues
2. Targeted checking against established best practices - exploiting the knowledge gained from past suggestions
By keeping these phases decoupled, the tool remains free to discover new or unseen issues and problems, while also learning from past experiences.
When presenting the suggestions generated by the `improve` tool, Qodo Merge will add a dedicated label for each suggestion generated from the auto best practices - 'Learned best practice':
![Auto best practice suggestion](https://www.qodo.ai/images/pr_agent/auto_best_practices.png){width=684}
## Auto Best Practices vs Custom Best Practices
Teams and companies can also manually define their own [custom best practices](https://qodo-merge-docs.qodo.ai/tools/improve/#best-practices) in Qodo Merge.
When custom best practices exist, Qodo Merge will still generate an 'auto best practices' wiki file, though it won't be used by the `improve` tool.
However, this auto-generated file can still serve two valuable purposes:
1. It can help enhance your custom best practices with additional insights derived from suggestions your team found valuable enough to implement
2. It demonstrates effective patterns for writing AI-friendly best practices
Even when using custom best practices, we recommend regularly reviewing the auto best practices file to refine your custom rules.
## Relevant configurations
```toml
[auto_best_practices]
# Disable all auto best practices usage or generation
enable_auto_best_practices = true
# Disable usage of auto best practices file in the 'improve' tool
utilize_auto_best_practices = true
# Extra instructions to the auto best practices generation prompt
extra_instructions = ""
# Max number of patterns to be detected
max_patterns = 5

## Introduction
The Git environment usually represents the final stage before code enters production. Hence, Detecting bugs and issues during the review process is critical.
The [`improve`](https://qodo-merge-docs.qodo.ai/tools/improve/) tool provides actionable code suggestions for your pull requests, aiming to help detect and fix bugs and problems.
By default, suggestions appear as a comment in a table format:
![code_suggestions_as_comment_closed.png](https://codium.ai/images/pr_agent/code_suggestions_as_comment_closed.png){width=512}
![code_suggestions_as_comment_open.png](https://codium.ai/images/pr_agent/code_suggestions_as_comment_open.png){width=512}
## Validation of Code Suggestions
Each suggestion in the table can be "applied" by clicking on the `Apply this suggestion` checkbox, converting it to a committable Git code change that can be committed directly to the PR.
This approach allows to fix issues without returning to your IDE for manual edits — significantly faster and more convenient.
However, committing a suggestion in a Git environment carries more risk than in a local IDE, as you don't have the opportunity to fully run and test the code before committing.
To balance convenience with safety, Qodo Merge implements a dual validation system for each generated code suggestion:
1) **Localization** - Qodo Merge confirms that the suggestion's line numbers and surrounding code, as predicted by the model, actually match the repo code. This means that the model correctly identified the context and location of the code to be changed.
2) **"Compilation"** - Using static code analysis, Qodo Merge verifies that after applying the suggestion, the modified file will still be valid, meaning tree-sitter syntax processing will not throw an error. This process is relevant for multiple programming languages, see [here](https://pypi.org/project/tree-sitter-languages/) for the full list of supported languages.
When a suggestion fails to meet these validation criteria, it may still provide valuable feedback, but isn't suitable for direct application to the PR.
In such cases, Qodo Merge will omit the 'apply' checkbox and instead display:
`[To ensure code accuracy, apply this suggestion manually]`
All suggestions that pass these validations undergo a final stage of **self-reflection**, where the AI model evaluates, scores, and re-ranks its own suggestions, eliminating any that are irrelevant or incorrect.
Read more about this process in the [self-reflection](https://qodo-merge-docs.qodo.ai/core-abilities/self_reflection/) page.
## Conclusion
The validation methods described above enhance the reliability of code suggestions and help PR authors determine which suggestions are safer to apply in the Git environment.
Of course, additional factors should be considered, such as suggestion complexity and potential code impact.
Human judgment remains essential. After clicking 'apply', Qodo Merge still presents the 'before' and 'after' code snippets for review, allowing you to assess the changes before finalizing the commit.

## TL;DR
Qodo Merge uses an **asymmetric and dynamic context strategy** to improve AI analysis of code changes in pull requests.
It provides more context before changes than after, and dynamically adjusts the context based on code structure (e.g., enclosing functions or classes).
This approach balances providing sufficient context for accurate analysis, while avoiding needle-in-the-haystack information overload that could degrade AI performance or exceed token limits.
## Introduction
Pull request code changes are retrieved in a unified diff format, showing three lines of context before and after each modified section, with additions marked by '+' and deletions by '-'.
```diff

...
```
This unified diff format can be challenging for AI models to interpret accurately, as it provides limited context for understanding the full scope of code changes.
The presentation of code using '+', '-', and ' ' symbols to indicate additions, deletions, and unchanged lines respectively also differs from the standard code formatting typically used to train AI models.
## Challenges of expanding the context window
While expanding the context window is technically feasible, it presents a more fundamental trade-off:
Pros:
- Enhanced context allows the model to better comprehend and localize the code changes, results (potentially) in more precise analysis and suggestions. Without enough context, the model may struggle to understand the code changes and provide relevant feedback.
Cons:
- Excessive context may overwhelm the model with extraneous information, creating a "needle in a haystack" scenario where focusing on the relevant details (the code that actually changed) becomes challenging.
LLM quality is known to degrade when the context gets larger.
Pull requests often encompass multiple changes across many files, potentially spanning hundreds of lines of modified code. This complexity presents a genuine risk of overwhelming the model with excessive context.
- Increased context expands the token count, increasing processing time and cost, and may prevent the model from processing the entire pull request in a single pass.
## Asymmetric and dynamic context
To address these challenges, Qodo Merge employs an **asymmetric** and **dynamic** context strategy, providing the model with more focused and relevant context information for each code change.
**Asymmetric:**
We start by recognizing that the context preceding a code change is typically more crucial for understanding the modification than the context following it.
Consequently, Qodo Merge implements an asymmetric context policy, decoupling the context window into two distinct segments: one for the code before the change and another for the code after.
By independently adjusting each context window, Qodo Merge can supply the model with a more tailored and pertinent context for individual code changes.
**Dynamic:**
We also employ a "dynamic" context strategy.
We start by recognizing that the optimal context for a code change often corresponds to its enclosing code component (e.g., function, class), rather than a fixed number of lines.
Consequently, we dynamically adjust the context window based on the code's structure, ensuring the model receives the most pertinent information for each modification.
To prevent overwhelming the model with excessive context, we impose a limit on the number of lines searched when identifying the enclosing component.
This balance allows for comprehensive understanding while maintaining efficiency and limiting context token usage.
## Appendix - relevant configuration options
```toml
[config]
patch_extension_skip_types =[".md",".txt"] # Skip files with these extensions when trying to extend the context
allow_dynamic_context=true # Allow dynamic context extension
max_extra_lines_before_dynamic_context = 8 # will try to include up to X extra lines before the hunk in the patch, until we reach an enclosing function or class
patch_extra_lines_before = 3 # Number of extra lines (+3 default ones) to include before each hunk in the patch
patch_extra_lines_after = 1 # Number of extra lines (+3 default ones) to include after each hunk in the patch

# Fetching Ticket Context for PRs
`Supported Git Platforms: GitHub, GitLab, Bitbucket`
## Overview
Qodo Merge streamlines code review workflows by seamlessly connecting with multiple ticket management systems.
This integration enriches the review process by automatically surfacing relevant ticket information and context alongside code changes.
**Ticket systems supported**:
- GitHub
- Jira (💎)
**Ticket data fetched:**
1. Ticket Title
2. Ticket Description
3. Custom Fields (Acceptance criteria)
4. Subtasks (linked tasks)
5. Labels
6. Attached Images/Screenshots
## Affected Tools
Ticket Recognition Requirements:
- The PR description should contain a link to the ticket or if the branch name starts with the ticket id / number.
- For Jira tickets, you should follow the instructions in [Jira Integration](https://qodo-merge-docs.qodo.ai/core-abilities/fetching_ticket_context/#jira-integration) in order to authenticate with Jira.
### Describe tool
Qodo Merge will recognize the ticket and use the ticket content (title, description, labels) to provide additional context for the code changes.
By understanding the reasoning and intent behind modifications, the LLM can offer more insightful and relevant code analysis.
### Review tool
Similarly to the `describe` tool, the `review` tool will use the ticket content to provide additional context for the code changes.
In addition, this feature will evaluate how well a Pull Request (PR) adheres to its original purpose/intent as defined by the associated ticket or issue mentioned in the PR description.
Each ticket will be assigned a label (Compliance/Alignment level), Indicates the degree to which the PR fulfills its original purpose, Options: Fully compliant, Partially compliant or Not compliant.
![Ticket Compliance](https://www.qodo.ai/images/pr_agent/ticket_compliance_review.png){width=768}
By default, the tool will automatically validate if the PR complies with the referenced ticket.
If you want to disable this feedback, add the following line to your configuration file:
```toml
[pr_reviewer]
require_ticket_analysis_review=false
```
## GitHub Issues Integration
Qodo Merge will automatically recognize GitHub issues mentioned in the PR description and fetch the issue content.
Examples of valid GitHub issue references:
- `https://github.com/<ORG_NAME>/<REPO_NAME>/issues/<ISSUE_NUMBER>`
- `#<ISSUE_NUMBER>`
- `<ORG_NAME>/<REPO_NAME>#<ISSUE_NUMBER>`
Since Qodo Merge is integrated with GitHub, it doesn't require any additional configuration to fetch GitHub issues.
## Jira Integration 💎
We support both Jira Cloud and Jira Server/Data Center.
### Jira Cloud
There are two ways to authenticate with Jira Cloud:
**1) Jira App Authentication**
The recommended way to authenticate with Jira Cloud is to install the Qodo Merge app in your Jira Cloud instance. This will allow Qodo Merge to access Jira data on your behalf.

#### Using Basic Authentication for Jira Data Center/Server
You can use your Jira username and password to authenticate with Jira Data Center/Server.
In your Configuration file/Environment variables/Secrets file, add the following lines:
```toml
jira_api_email = "your_username"
jira_api_token = "your_password"
```
(Note that indeed the 'jira_api_email' field is used for the username, and the 'jira_api_token' field is used for the user password.)
##### Validating Basic authentication via Python script
If you are facing issues retrieving tickets in Qodo Merge with Basic auth, you can validate the flow using a Python script.
This following steps will help you check if the basic auth is working correctly, and if you can access the Jira ticket details:
1. run `pip install jira==3.8.0`
2. run the following Python script (after replacing the placeholders with your actual values):
??? example "Script to validate basic auth"
```python
from jira import JIRA
if __name__ == "__main__":
try:
# Jira server URL
server = "https://..."
# Basic auth
username = "..."
password = "..."
# Jira ticket code (e.g. "PROJ-123")
ticket_id = "..."
print("Initializing JiraServerTicketProvider with JIRA server")
# Initialize JIRA client
jira = JIRA(
server=server,
basic_auth=(username, password),
timeout=30
)
if jira:
print(f"JIRA client initialized successfully")
else:
print("Error initializing JIRA client")
# Fetch ticket details
ticket = jira.issue(ticket_id)
print(f"Ticket title: {ticket.fields.summary}")
except Exception as e:
print(f"Error fetching JIRA ticket details: {e}")
```
#### Using a Personal Access Token (PAT) for Jira Data Center/Server
1. Create a [Personal Access Token (PAT)](https://confluence.atlassian.com/enterprise/using-personal-access-tokens-1026032365.html) in your Jira account
2. In your Configuration file/Environment variables/Secrets file, add the following lines:
```toml
[jira]
jira_base_url = "YOUR_JIRA_BASE_URL" # e.g. https://jira.example.com
jira_api_token = "YOUR_API_TOKEN"
```
##### Validating PAT token via Python script
If you are facing issues retrieving tickets in Qodo Merge with PAT token, you can validate the flow using a Python script.
This following steps will help you check if the token is working correctly, and if you can access the Jira ticket details:
1. run `pip install jira==3.8.0`
2. run the following Python script (after replacing the placeholders with your actual values):
??? example "Script to validate PAT token"
```python
from jira import JIRA
if __name__ == "__main__":
try:
# Jira server URL
server = "https://..."
# Jira PAT token
token_auth = "..."
# Jira ticket code (e.g. "PROJ-123")
ticket_id = "..."
print("Initializing JiraServerTicketProvider with JIRA server")
# Initialize JIRA client
jira = JIRA(
server=server,
token_auth=token_auth,
timeout=30
)
if jira:
print(f"JIRA client initialized successfully")
else:
print("Error initializing JIRA client")
# Fetch ticket details
ticket = jira.issue(ticket_id)
print(f"Ticket title: {ticket.fields.summary}")
except Exception as e:
print(f"Error fetching JIRA ticket details: {e}")
```
### How to link a PR to a Jira ticket
To integrate with Jira, you can link your PR to a ticket using either of these methods:
**Method 1: Description Reference:**
Include a ticket reference in your PR description using either the complete URL format https://<JIRA_ORG>.atlassian.net/browse/ISSUE-123 or the shortened ticket ID ISSUE-123.
**Method 2: Branch Name Detection:**
Name your branch with the ticket ID as a prefix (e.g., `ISSUE-123-feature-description` or `ISSUE-123/feature-description`).
!!! note "Jira Base URL"
For shortened ticket IDs or branch detection (method 2 for JIRA cloud), you must configure the Jira base URL in your configuration file under the [jira] section:
```toml
[jira]
jira_base_url = "https://<JIRA_ORG>.atlassian.net"
```

# Overview - Impact Evaluation 💎
Demonstrating the return on investment (ROI) of AI-powered initiatives is crucial for modern organizations.
To address this need, Qodo Merge has developed an AI impact measurement tools and metrics, providing advanced analytics to help businesses quantify the tangible benefits of AI adoption in their PR review process.
## Auto Impact Validator - Real-Time Tracking of Implemented Qodo Merge Suggestions
### How It Works
When a user pushes a new commit to the pull request, Qodo Merge automatically compares the updated code against the previous suggestions, marking them as implemented if the changes address these recommendations, whether directly or indirectly:
1. **Direct Implementation:** The user directly addresses the suggestion as-is in the PR, either by clicking on the "apply code suggestion" checkbox or by making the changes manually.
2. **Indirect Implementation:** Qodo Merge recognizes when a suggestion's intent is fulfilled, even if the exact code changes differ from the original recommendation. It marks these suggestions as implemented, acknowledging that users may achieve the same goal through alternative solutions.
### Real-Time Visual Feedback
Upon confirming that a suggestion was implemented, Qodo Merge automatically adds a ✅ (check mark) to the relevant suggestion, enabling transparent tracking of Qodo Merge's impact analysis.
Qodo Merge will also add, inside the relevant suggestions, an explanation of how the new code was impacted by each suggestion.
![Suggestion_checkmark](https://codium.ai/images/pr_agent/auto_suggestion_checkmark.png){width=512}
### Dashboard Metrics
The dashboard provides macro-level insights into the overall impact of Qodo Merge on the pull-request process with key productivity metrics.
By offering clear, data-driven evidence of Qodo Merge's impact, it empowers leadership teams to make informed decisions about the tool's effectiveness and ROI.
Here are key metrics that the dashboard tracks:
#### Qodo Merge Impacts per 1K Lines
![Dashboard](https://codium.ai/images/pr_agent/impacts_per_1k_llines.png){width=512}
> Explanation: for every 1K lines of code (additions/edits), Qodo Merge had on average ~X suggestions implemented.
**Why This Metric Matters:**
1. **Standardized and Comparable Measurement:** By measuring impacts per 1K lines of code additions, you create a standardized metric that can be compared across different projects, teams, customers, and time periods. This standardization is crucial for meaningful analysis, benchmarking, and identifying where Qodo Merge is most effective.
2. **Accounts for PR Variability and Incentivizes Quality:** This metric addresses the fact that "Not all PRs are created equal." By normalizing against lines of code rather than PR count, you account for the variability in PR sizes and focus on the quality and impact of suggestions rather than just the number of PRs affected.
3. **Quantifies Value and ROI:** The metric directly correlates with the value Qodo Merge is providing, showing how frequently it offers improvements relative to the amount of new code being written. This provides a clear, quantifiable way to demonstrate Qodo Merge's return on investment to stakeholders.
#### Suggestion Effectiveness Across Categories
![Impacted_Suggestion_Score](https://codium.ai/images/pr_agent/impact_by_category.png){width=512}
> Explanation: This chart illustrates the distribution of implemented suggestions across different categories, enabling teams to better understand Qodo Merge's impact on various aspects of code quality and development practices.
#### Suggestion Score Distribution
![Impacted_Suggestion_Score](https://codium.ai/images/pr_agent/impacted_score_dist.png){width=512}
> Explanation: The distribution of the suggestion score for the implemented suggestions, ensuring that higher-scored suggestions truly represent more significant improvements.

# Interactivity
`Supported Git Platforms: GitHub, GitLab`
## Overview
Qodo Merge transforms static code reviews into interactive experiences by enabling direct actions from pull request (PR) comments.
Developers can immediately trigger actions and apply changes with simple checkbox clicks.
This focused workflow maintains context while dramatically reducing the time between PR creation and final merge.
The approach eliminates manual steps, provides clear visual indicators, and creates immediate feedback loops all within the same interface.
## Key Interactive Features
### 1\. Interactive `/improve` Tool
The [`/improve`](https://qodo-merge-docs.qodo.ai/tools/improve/) command delivers a comprehensive interactive experience:
- _**Apply this suggestion**_: Clicking this checkbox instantly converts a suggestion into a committable code change. When committed to the PR, changes made to code that was flagged for improvement will be marked with a check mark, allowing developers to easily track and review implemented recommendations.
- _**More**_: Triggers additional suggestions generation while keeping each suggestion focused and relevant as the original set
- _**Update**_: Triggers a re-analysis of the code, providing updated suggestions based on the latest changes
- _**Author self-review**_: Interactive acknowledgment that developers have opened and reviewed collapsed suggestions
### 2\. Interactive `/analyze` Tool
The [`/analyze`](https://qodo-merge-docs.qodo.ai/tools/analyze/) command provides component-level analysis with interactive options for each identified code component:
- Interactive checkboxes to generate tests, documentation, and code suggestions for specific components
- On-demand similar code search that activates when a checkbox is clicked
- Component-specific actions that trigger only for the selected elements, providing focused assistance
### 3\. Interactive `/help` Tool
The [`/help`](https://qodo-merge-docs.qodo.ai/tools/help/) command not only lists available tools and their descriptions but also enables immediate tool invocation through interactive checkboxes.
When a user checks a tool's checkbox, Qodo Merge instantly triggers that tool without requiring additional commands.
This transforms the standard help menu into an interactive launch pad for all Qodo Merge capabilities, eliminating context switching by keeping developers within their PR workflow.

## Local and global metadata injection with multi-stage analysis
1\.
Qodo Merge initially retrieves for each PR the following data:
- PR title and branch name
- PR original description
- Commit messages history
- PR diff patches, in [hunk diff](https://loicpefferkorn.net/2014/02/diff-files-what-are-hunks-and-how-to-extract-them/) format
- The entire content of the files that were modified in the PR
!!! tip "Tip: Organization-level metadata"
In addition to the inputs above, Qodo Merge can incorporate supplementary preferences provided by the user, like [`extra_instructions` and `organization best practices`](https://qodo-merge-docs.qodo.ai/tools/improve/#extra-instructions-and-best-practices). This information can be used to enhance the PR analysis.
2\.
By default, the first command that Qodo Merge executes is [`describe`](https://qodo-merge-docs.qodo.ai/tools/describe/), which generates three types of outputs:
- PR Type (e.g. bug fix, feature, refactor, etc)
- PR Description - a bullet point summary of the PR
- Changes walkthrough - for each modified file, provide a one-line summary followed by a detailed bullet point list of the changes.
These AI-generated outputs are now considered as part of the PR metadata, and can be used in subsequent commands like `review` and `improve`.
This effectively enables multi-stage chain-of-thought analysis, without doing any additional API calls which will cost time and money.
For example, when generating code suggestions for different files, Qodo Merge can inject the AI-generated ["Changes walkthrough"](https://github.com/Codium-ai/pr-agent/pull/1202#issue-2511546839) file summary in the prompt:
```diff
## File: 'src/file1.py'
### AI-generated file summary:
- edited function `func1` that does X
- Removed function `func2` that was not used
- ....
@@ ... @@ def func1():
__new hunk__
11 unchanged code line0
12 unchanged code line1
13 +new code line2 added
14 unchanged code line3
__old hunk__
unchanged code line0
unchanged code line1
-old code line2 removed
unchanged code line3
@@ ... @@ def func2():
__new hunk__
...
__old hunk__
...
```
3\. The entire PR files that were retrieved are also used to expand and enhance the PR context (see [Dynamic Context](https://qodo-merge-docs.qodo.ai/core-abilities/dynamic_context/)).
4\. All the metadata described above represents several level of cumulative analysis - ranging from hunk level, to file level, to PR level, to organization level.
This comprehensive approach enables Qodo Merge AI models to generate more precise and contextually relevant suggestions and feedback.

# RAG Context Enrichment 💎
`Supported Git Platforms: GitHub, Bitbucket Data Center`
!!! info "Prerequisites"
- RAG is available only for Qodo enterprise plan users, with single tenant or on-premises setup.
- Database setup and codebase indexing must be completed before proceeding. [Contact support](https://www.qodo.ai/contact/) for more information.
## Overview
### What is RAG Context Enrichment?
A feature that enhances AI analysis by retrieving and referencing relevant code patterns from your project, enabling context-aware insights during code reviews.
### How does RAG Context Enrichment work?
Using Retrieval-Augmented Generation (RAG), it searches your configured repositories for contextually relevant code segments, enriching pull request (PR) insights and accelerating review accuracy.
## Getting started
### Configuration options
In order to enable the RAG feature, add the following lines to your configuration file:
```toml
[rag_arguments]
enable_rag=true
```
!!! example "RAG Arguments Options"
<table>
<tr>
<td><b>enable_rag</b></td>
<td>If set to true, repository enrichment using RAG will be enabled. Default is false.</td>
</tr>
<tr>
<td><b>rag_repo_list</b></td>
<td>A list of repositories that will be used by the semantic search for RAG. Use `['all']` to consider the entire codebase or a select list of repositories, for example: ['my-org/my-repo', ...]. Default: the repository from which the PR was opened.</td>
</tr>
</table>
### Applications
RAG capability is exclusively available in the following tools:
=== "`/review`"
The [`/review`](https://qodo-merge-docs.qodo.ai/tools/review/) tool offers the _Focus area from RAG data_ which contains feedback based on the RAG references analysis.
The complete list of references found relevant to the PR will be shown in the _References_ section, helping developers understand the broader context by exploring the provided references.
![RAGed review tool](https://codium.ai/images/pr_agent/rag_review.png){width=640}
=== "`/implement`"
The [`/implement`](https://qodo-merge-docs.qodo.ai/tools/implement/) tool utilizes the RAG feature to provide comprehensive context of the repository codebase, allowing it to generate more refined code output.
The _References_ section contains links to the content used to support the code generation.
![RAGed implement tool](https://codium.ai/images/pr_agent/rag_implement.png){width=640}
=== "`/ask`"
The [`/ask`](https://qodo-merge-docs.qodo.ai/tools/ask/) tool can access broader repository context through the RAG feature when answering questions that go beyond the PR scope alone.
The _References_ section displays the additional repository content consulted to formulate the answer.
![RAGed ask tool](https://codium.ai/images/pr_agent/rag_ask.png){width=640}
## Limitations
### Querying the codebase presents significant challenges
- **Search Method**: RAG uses natural language queries to find semantically relevant code sections
- **Result Quality**: No guarantee that RAG results will be useful for all queries
- **Scope Recommendation**: To reduce noise, focus on the PR repository rather than searching across multiple repositories
### This feature has several requirements and restrictions
- **Codebase**: Must be properly indexed for search functionality
- **Security**: Requires secure and private indexed codebase implementation
- **Deployment**: Only available for Qodo Merge Enterprise plan using single tenant or on-premises setup

## TL;DR
Qodo Merge implements a **self-reflection** process where the AI model reflects, scores, and re-ranks its own suggestions, eliminating irrelevant or incorrect ones.
This approach improves the quality and relevance of suggestions, saving users time and enhancing their experience.
Configuration options allow users to set a score threshold for further filtering out suggestions.
## Introduction - Efficient Review with Hierarchical Presentation
Given that not all generated code suggestions will be relevant, it is crucial to enable users to review them in a fast and efficient way, allowing quick identification and filtering of non-applicable ones.
To achieve this goal, Qodo Merge offers a dedicated hierarchical structure when presenting suggestions to users:
- A "category" section groups suggestions by their category, allowing users to quickly dismiss irrelevant suggestions.
- Each suggestion is first described by a one-line summary, which can be expanded to a full description by clicking on a collapsible.
- Upon expanding a suggestion, the user receives a more comprehensive description, and a code snippet demonstrating the recommendation.
!!! note "Fast Review"
This hierarchical structure is designed to facilitate rapid review of each suggestion, with users spending an average of ~5-10 seconds per item.
## Self-reflection and Re-ranking
The AI model is initially tasked with generating suggestions, and outputting them in order of importance.
However, in practice we observe that models often struggle to simultaneously generate high-quality code suggestions and rank them well in a single pass.
Furthermore, the initial set of generated suggestions sometimes contains easily identifiable errors.
To address these issues, we implemented a "self-reflection" process that refines suggestion ranking and eliminates irrelevant or incorrect proposals.
This process consists of the following steps:
1. Presenting the generated suggestions to the model in a follow-up call.
2. Instructing the model to score each suggestion on a scale of 0-10 and provide a rationale for the assigned score.
3. Utilizing these scores to re-rank the suggestions and filter out incorrect ones (with a score of 0).
4. Optionally, filtering out all suggestions below a user-defined score threshold.
Note that presenting all generated suggestions simultaneously provides the model with a comprehensive context, enabling it to make more informed decisions compared to evaluating each suggestion individually.
To conclude, the self-reflection process enables Qodo Merge to prioritize suggestions based on their importance, eliminate inaccurate or irrelevant proposals, and optionally exclude suggestions that fall below a specified threshold of significance.
This results in a more refined and valuable set of suggestions for the user, saving time and improving the overall experience.

## Overview - Static Code Analysis 💎
By combining static code analysis with LLM capabilities, Qodo Merge can provide a comprehensive analysis of the PR code changes on a component level.
It scans the PR code changes, finds all the code components (methods, functions, classes) that changed, and enables to interactively generate tests, docs, code suggestions and similar code search for each component.
!!! note "Language that are currently supported:"
Python, Java, C++, JavaScript, TypeScript, C#.
## Capabilities
### Analyze PR
The [`analyze`](https://qodo-merge-docs.qodo.ai/tools/analyze/) tool enables to interactively generate tests, docs, code suggestions and similar code search for each component that changed in the PR.
It can be invoked manually by commenting on any PR:
```
/analyze
```
An example result:
![Analyze 1](https://codium.ai/images/pr_agent/analyze_1.png){width=768}
Clicking on each checkbox will trigger the relevant tool for the selected component.
### Generate Tests
The [`test`](https://qodo-merge-docs.qodo.ai/tools/test/) tool generate tests for a selected component, based on the PR code changes.
It can be invoked manually by commenting on any PR:
```
/test component_name
```
where 'component_name' is the name of a specific component in the PR, Or be triggered interactively by using the `analyze` tool.
![test1](https://codium.ai/images/pr_agent/test1.png){width=768}
### Generate Docs for a Component
The [`add_docs`](https://qodo-merge-docs.qodo.ai/tools/documentation/) tool scans the PR code changes, and automatically generate docstrings for any code components that changed in the PR.
It can be invoked manually by commenting on any PR:
```
/add_docs component_name
```
Or be triggered interactively by using the `analyze` tool.
![Docs single component](https://codium.ai/images/pr_agent/docs_single_component.png){width=768}
### Generate Code Suggestions for a Component
The [`improve_component`](https://qodo-merge-docs.qodo.ai/tools/improve_component/) tool generates code suggestions for a specific code component that changed in the PR.
It can be invoked manually by commenting on any PR:
```
/improve_component component_name
```
Or be triggered interactively by using the `analyze` tool.
![improve_component2](https://codium.ai/images/pr_agent/improve_component2.png){width=768}
### Find Similar Code
The [`similar code`](https://qodo-merge-docs.qodo.ai/tools/similar_code/) tool retrieves the most similar code components from inside the organization's codebase or from open-source code, including details about the license associated with each repository.
For example:
`Global Search` for a method called `chat_completion`:
![similar code global](https://codium.ai/images/pr_agent/similar_code_global2.png){width=768}

# FAQ
??? note "Q: Can Qodo Merge serve as a substitute for a human reviewer?"
#### Answer:<span style="display:none;">1</span>
Qodo Merge is designed to assist, not replace, human reviewers.
Reviewing PRs is a tedious and time-consuming task often seen as a "chore". In addition, the longer the PR the shorter the relative feedback, since long PRs can overwhelm reviewers, both in terms of technical difficulty, and the actual review time.
Qodo Merge aims to address these pain points, and to assist and empower both the PR author and reviewer.
However, Qodo Merge has built-in safeguards to ensure the developer remains in the driver's seat. For example:
1. Preserves user's original PR header
2. Places user's description above the AI-generated PR description
3. Won't approve PRs; approval remains reviewer's responsibility
4. The code suggestions are optional, and aim to:
- Encourage self-review and self-reflection
- Highlight potential bugs or oversights
- Enhance code quality and promote best practices
Read more about this issue in our [blog](https://www.codium.ai/blog/understanding-the-challenges-and-pain-points-of-the-pull-request-cycle/)
___
??? note "Q: I received an incorrect or irrelevant suggestion. Why?"
#### Answer:<span style="display:none;">2</span>
- Modern AI models, like Claude Sonnet and GPT-4, are improving rapidly but remain imperfect. Users should critically evaluate all suggestions rather than accepting them automatically.
- AI errors are rare, but possible. A main value from reviewing the code suggestions lies in their high probability of catching **mistakes or bugs made by the PR author**. We believe it's worth spending 30-60 seconds reviewing suggestions, even if some aren't relevant, as this practice can enhance code quality and prevent bugs in production.
- The hierarchical structure of the suggestions is designed to help the user _quickly_ understand them, and to decide which ones are relevant and which are not:
- Only if the `Category` header is relevant, the user should move to the summarized suggestion description.
- Only if the summarized suggestion description is relevant, the user should click on the collapsible, to read the full suggestion description with a code preview example.
- In addition, we recommend to use the [`extra_instructions`](https://qodo-merge-docs.qodo.ai/tools/improve/#extra-instructions-and-best-practices) field to guide the model to suggestions that are more relevant to the specific needs of the project.
- The interactive [PR chat](https://qodo-merge-docs.qodo.ai/chrome-extension/) also provides an easy way to get more tailored suggestions and feedback from the AI model.
___
??? note "Q: How can I get more tailored suggestions?"
#### Answer:<span style="display:none;">3</span>
See [here](https://qodo-merge-docs.qodo.ai/tools/improve/#extra-instructions-and-best-practices) for more information on how to use the `extra_instructions` and `best_practices` configuration options, to guide the model to more tailored suggestions.
___
??? note "Q: Will you store my code? Are you using my code to train models?"
#### Answer:<span style="display:none;">4</span>
No. Qodo Merge strict privacy policy ensures that your code is not stored or used for training purposes.
For a detailed overview of our data privacy policy, please refer to [this link](https://qodo-merge-docs.qodo.ai/overview/data_privacy/)
___
??? note "Q: Can I use my own LLM keys with Qodo Merge?"
#### Answer:<span style="display:none;">5</span>
When you self-host the [open-source](https://github.com/Codium-ai/pr-agent) version, you use your own keys.
Qodo Merge with SaaS deployment is a hosted version of Qodo Merge, where Qodo manages the infrastructure and the keys.
For enterprise customers, on-prem deployment is also available. [Contact us](https://www.codium.ai/contact/#pricing) for more information.
___
??? note "Q: Can Qodo Merge review draft/offline PRs?"
#### Answer:<span style="display:none;">5</span>
Yes. While Qodo Merge won't automatically review draft PRs, you can still get feedback by manually requesting it through [online commenting](https://qodo-merge-docs.qodo.ai/usage-guide/automations_and_usage/#online-usage).
For active PRs, you can customize the automatic feedback settings [here](https://qodo-merge-docs.qodo.ai/usage-guide/automations_and_usage/#qodo-merge-automatic-feedback) to match your team's workflow.
___
??? note "Q: Can the 'Review effort' feedback be calibrated or customized?"
#### Answer:<span style="display:none;">5</span>
Yes, you can customize review effort estimates using the `extra_instructions` configuration option (see [documentation](https://qodo-merge-docs.qodo.ai/tools/review/#configuration-options)).
Example mapping:
- Effort 1: < 30 minutes review time
- Effort 2: 30-60 minutes review time
- Effort 3: 60-90 minutes review time
- ...
Note: The effort levels (1-5) are primarily meant for _comparative_ purposes, helping teams prioritize reviewing smaller PRs first. The actual review duration may vary, as the focus is on providing consistent relative effort estimates.

## Azure DevOps Pipeline
You can use a pre-built Action Docker image to run PR-Agent as an Azure devops pipeline.
add the following file to your repository under `azure-pipelines.yml`:
```yaml
# Opt out of CI triggers
trigger: none
# Configure PR trigger
pr:
branches:
include:
- '*'
autoCancel: true
drafts: false
stages:
- stage: pr_agent
displayName: 'PR Agent Stage'
jobs:
- job: pr_agent_job
displayName: 'PR Agent Job'
pool:
vmImage: 'ubuntu-latest'
container:
image: codiumai/pr-agent:latest
options: --entrypoint ""
variables:
- group: pr_agent
steps:
- script: |
echo "Running PR Agent action step"
# Construct PR_URL
PR_URL="${SYSTEM_COLLECTIONURI}${SYSTEM_TEAMPROJECT}/_git/${BUILD_REPOSITORY_NAME}/pullrequest/${SYSTEM_PULLREQUEST_PULLREQUESTID}"
echo "PR_URL=$PR_URL"
# Extract organization URL from System.CollectionUri
ORG_URL=$(echo "$(System.CollectionUri)" | sed 's/\/$//') # Remove trailing slash if present
echo "Organization URL: $ORG_URL"
export azure_devops__org="$ORG_URL"
export config__git_provider="azure"
pr-agent --pr_url="$PR_URL" describe
pr-agent --pr_url="$PR_URL" review
pr-agent --pr_url="$PR_URL" improve
env:
azure_devops__pat: $(azure_devops_pat)
openai__key: $(OPENAI_KEY)
displayName: 'Run Qodo Merge'
```
This script will run Qodo Merge on every new merge request, with the `improve`, `review`, and `describe` commands.
Note that you need to export the `azure_devops__pat` and `OPENAI_KEY` variables in the Azure DevOps pipeline settings (Pipelines -> Library -> + Variable group):
![Qodo Merge](https://codium.ai/images/pr_agent/azure_devops_pipeline_secrets.png){width=468}
Make sure to give pipeline permissions to the `pr_agent` variable group.
> Note that Azure Pipelines lacks support for triggering workflows from PR comments. If you find a viable solution, please contribute it to our [issue tracker](https://github.com/Codium-ai/pr-agent/issues)
## Azure DevOps from CLI
To use Azure DevOps provider use the following settings in configuration.toml:
```toml
[config]
git_provider="azure"
```
Azure DevOps provider supports [PAT token](https://learn.microsoft.com/en-us/azure/devops/organizations/accounts/use-personal-access-tokens-to-authenticate?view=azure-devops&tabs=Windows) or [DefaultAzureCredential](https://learn.microsoft.com/en-us/azure/developer/python/sdk/authentication-overview#authentication-in-server-environments) authentication.
PAT is faster to create, but has build in expiration date, and will use the user identity for API calls.
Using DefaultAzureCredential you can use managed identity or Service principle, which are more secure and will create separate ADO user identity (via AAD) to the agent.
If PAT was chosen, you can assign the value in .secrets.toml.
If DefaultAzureCredential was chosen, you can assigned the additional env vars like AZURE_CLIENT_SECRET directly,
or use managed identity/az cli (for local development) without any additional configuration.
in any case, 'org' value must be assigned in .secrets.toml:
```toml
[azure_devops]
org = "https://dev.azure.com/YOUR_ORGANIZATION/"
# pat = "YOUR_PAT_TOKEN" needed only if using PAT for authentication
```
## Azure DevOps Webhook
To trigger from an Azure webhook, you need to manually [add a webhook](https://learn.microsoft.com/en-us/azure/devops/service-hooks/services/webhooks?view=azure-devops).
Use the "Pull request created" type to trigger a review, or "Pull request commented on" to trigger any supported comment with /<command> <args> comment on the relevant PR. Note that for the "Pull request commented on" trigger, only API v2.0 is supported.
For webhook security, create a sporadic username/password pair and configure the webhook username and password on both the server and Azure DevOps webhook. These will be sent as basic Auth data by the webhook with each request:
```toml
[azure_devops_server]
webhook_username = "<basic auth user>"
webhook_password = "<basic auth password>"
```
> :warning: **Ensure that the webhook endpoint is only accessible over HTTPS** to mitigate the risk of credential interception when using basic authentication.

## Run as a Bitbucket Pipeline
You can use the Bitbucket Pipeline system to run PR-Agent on every pull request open or update.
1. Add the following file in your repository bitbucket-pipelines.yml
```yaml
pipelines:
pull-requests:
'**':
- step:
name: PR Agent Review
image: codiumai/pr-agent:latest
script:
- pr-agent --pr_url=https://bitbucket.org/$BITBUCKET_WORKSPACE/$BITBUCKET_REPO_SLUG/pull-requests/$BITBUCKET_PR_ID review
```
2. Add the following secure variables to your repository under Repository settings > Pipelines > Repository variables.
- CONFIG__GIT_PROVIDER: `bitbucket`
- OPENAI__KEY: `<your key>`
- BITBUCKET__AUTH_TYPE: `basic` or `bearer` (default is `bearer`)
- BITBUCKET__BEARER_TOKEN: `<your token>` (required when auth_type is bearer)
- BITBUCKET__BASIC_TOKEN: `<your token>` (required when auth_type is basic)
You can get a Bitbucket token for your repository by following Repository Settings -> Security -> Access Tokens.
For basic auth, you can generate a base64 encoded token from your username:password combination.
Note that comments on a PR are not supported in Bitbucket Pipeline.
## Bitbucket Server and Data Center
Login into your on-prem instance of Bitbucket with your service account username and password.
Navigate to `Manage account`, `HTTP Access tokens`, `Create Token`.
Generate the token and add it to .secret.toml under `bitbucket_server` section
```toml
[bitbucket_server]
bearer_token = "<your key>"
```
### Run it as CLI
Modify `configuration.toml`:
```toml
git_provider="bitbucket_server"
```
and pass the Pull request URL:
```shell
python cli.py --pr_url https://git.onpreminstanceofbitbucket.com/projects/PROJECT/repos/REPO/pull-requests/1 review
```
### Run it as service
To run PR-Agent as webhook, build the docker image:
```bash
docker build . -t codiumai/pr-agent:bitbucket_server_webhook --target bitbucket_server_webhook -f docker/Dockerfile
docker push codiumai/pr-agent:bitbucket_server_webhook # Push to your Docker repository
```
Navigate to `Projects` or `Repositories`, `Settings`, `Webhooks`, `Create Webhook`.
Fill the name and URL, Authentication None select the Pull Request Opened checkbox to receive that event as webhook.
The URL should end with `/webhook`, for example: https://domain.com/webhook

## Run as a GitHub Action
You can use our pre-built Github Action Docker image to run PR-Agent as a Github Action.
1) Add the following file to your repository under `.github/workflows/pr_agent.yml`:
```yaml
on:
pull_request:
types: [opened, reopened, ready_for_review]
issue_comment:
jobs:
pr_agent_job:
if: ${{ github.event.sender.type != 'Bot' }}
runs-on: ubuntu-latest
permissions:
issues: write
pull-requests: write
contents: write
name: Run pr agent on every pull request, respond to user comments
steps:
- name: PR Agent action step
id: pragent
uses: qodo-ai/pr-agent@main
env:
OPENAI_KEY: ${{ secrets.OPENAI_KEY }}
GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
```
2) Add the following secret to your repository under `Settings > Secrets and variables > Actions > New repository secret > Add secret`:
```
Name = OPENAI_KEY
Secret = <your key>
```
The GITHUB_TOKEN secret is automatically created by GitHub.
3) Merge this change to your main branch.
When you open your next PR, you should see a comment from `github-actions` bot with a review of your PR, and instructions on how to use the rest of the tools.
4) You may configure Qodo Merge by adding environment variables under the env section corresponding to any configurable property in the [configuration](https://github.com/Codium-ai/pr-agent/blob/main/pr_agent/settings/configuration.toml) file. Some examples:
```yaml
env:
# ... previous environment values
OPENAI.ORG: "<Your organization name under your OpenAI account>"
PR_REVIEWER.REQUIRE_TESTS_REVIEW: "false" # Disable tests review
PR_CODE_SUGGESTIONS.NUM_CODE_SUGGESTIONS: 6 # Increase number of code suggestions
```
See detailed usage instructions in the [USAGE GUIDE](https://qodo-merge-docs.qodo.ai/usage-guide/automations_and_usage/#github-action)
### Using a specific release
!!! tip ""
if you want to pin your action to a specific release (v0.23 for example) for stability reasons, use:
```yaml
...
steps:
- name: PR Agent action step
id: pragent
uses: docker://codiumai/pr-agent:0.23-github_action
...
```
For enhanced security, you can also specify the Docker image by its [digest](https://hub.docker.com/repository/docker/codiumai/pr-agent/tags):
```yaml
...
steps:
- name: PR Agent action step
id: pragent
uses: docker://codiumai/pr-agent@sha256:14165e525678ace7d9b51cda8652c2d74abb4e1d76b57c4a6ccaeba84663cc64

```
### Action for GitHub enterprise server
!!! tip ""
To use the action with a GitHub enterprise server, add an environment variable `GITHUB.BASE_URL` with the API URL of your GitHub server.
For example, if your GitHub server is at `https://github.mycompany.com`, add the following to your workflow file:
```yaml
env:
# ... previous environment values
GITHUB.BASE_URL: "https://github.mycompany.com/api/v3"
```

## Run as a GitHub App
Allowing you to automate the review process on your private or public repositories.
1) Create a GitHub App from the [Github Developer Portal](https://docs.github.com/en/developers/apps/creating-a-github-app).
- Set the following permissions:
- Pull requests: Read & write
- Issue comment: Read & write
- Metadata: Read-only
- Contents: Read-only
- Set the following events:
- Issue comment
- Pull request
- Push (if you need to enable triggering on PR update)
2) Generate a random secret for your app, and save it for later. For example, you can use:
```bash
WEBHOOK_SECRET=$(python -c "import secrets; print(secrets.token_hex(10))")
```
3) Acquire the following pieces of information from your app's settings page:
- App private key (click "Generate a private key" and save the file)
- App ID
4) Clone this repository:
```bash
git clone https://github.com/Codium-ai/pr-agent.git
```
5) Copy the secrets template file and fill in the following:
```bash
cp pr_agent/settings/.secrets_template.toml pr_agent/settings/.secrets.toml
# Edit .secrets.toml file
```
- Your OpenAI key.
- Copy your app's private key to the private_key field.
- Copy your app's ID to the app_id field.
- Copy your app's webhook secret to the webhook_secret field.
- Set deployment_type to 'app' in [configuration.toml](https://github.com/Codium-ai/pr-agent/blob/main/pr_agent/settings/configuration.toml)
> The .secrets.toml file is not copied to the Docker image by default, and is only used for local development.
> If you want to use the .secrets.toml file in your Docker image, you can add remove it from the .dockerignore file.
> In most production environments, you would inject the secrets file as environment variables or as mounted volumes.
> For example, in order to inject a secrets file as a volume in a Kubernetes environment you can update your pod spec to include the following,
> assuming you have a secret named `pr-agent-settings` with a key named `.secrets.toml`:
```
volumes:
- name: settings-volume
secret:
secretName: pr-agent-settings
// ...
containers:
// ...
volumeMounts:
- mountPath: /app/pr_agent/settings_prod
name: settings-volume
```
> Another option is to set the secrets as environment variables in your deployment environment, for example `OPENAI.KEY` and `GITHUB.USER_TOKEN`.
6) Build a Docker image for the app and optionally push it to a Docker repository. We'll use Dockerhub as an example:
```bash
docker build . -t codiumai/pr-agent:github_app --target github_app -f docker/Dockerfile
docker push codiumai/pr-agent:github_app # Push to your Docker repository
```
7. Host the app using a server, serverless function, or container environment. Alternatively, for development and
debugging, you may use tools like smee.io to forward webhooks to your local machine.
You can check [Deploy as a Lambda Function](#deploy-as-a-lambda-function)
8. Go back to your app's settings, and set the following:
- Webhook URL: The URL of your app's server or the URL of the smee.io channel.
- Webhook secret: The secret you generated earlier.
9. Install the app by navigating to the "Install App" tab and selecting your desired repositories.
> **Note:** When running Qodo Merge from GitHub app, the default configuration file (configuration.toml) will be loaded.
> However, you can override the default tool parameters by uploading a local configuration file `.pr_agent.toml`
> For more information please check out the [USAGE GUIDE](../usage-guide/automations_and_usage.md#github-app)
---
## Deploy as a Lambda Function
Note that since AWS Lambda env vars cannot have "." in the name, you can replace each "." in an env variable with "__".<br>
For example: `GITHUB.WEBHOOK_SECRET` --> `GITHUB__WEBHOOK_SECRET`
1. Follow steps 1-5 from [here](#run-as-a-github-app).
2. Build a docker image that can be used as a lambda function
```shell
docker buildx build --platform=linux/amd64 . -t codiumai/pr-agent:serverless -f docker/Dockerfile.lambda
```
3. Push image to ECR
```shell
docker tag codiumai/pr-agent:serverless <AWS_ACCOUNT>.dkr.ecr.<AWS_REGION>.amazonaws.com/codiumai/pr-agent:serverless
docker push <AWS_ACCOUNT>.dkr.ecr.<AWS_REGION>.amazonaws.com/codiumai/pr-agent:serverless
```
4. Create a lambda function that uses the uploaded image. Set the lambda timeout to be at least 3m.
5. Configure the lambda function to have a Function URL.
6. In the environment variables of the Lambda function, specify `AZURE_DEVOPS_CACHE_DIR` to a writable location such as /tmp. (see [link](https://github.com/Codium-ai/pr-agent/pull/450#issuecomment-1840242269))
7. Go back to steps 8-9 of [Method 5](#run-as-a-github-app) with the function url as your Webhook URL.
The Webhook URL would look like `https://<LAMBDA_FUNCTION_URL>/api/v1/github_webhooks`
---
## AWS CodeCommit Setup
Not all features have been added to CodeCommit yet. As of right now, CodeCommit has been implemented to run the Qodo Merge CLI on the command line, using AWS credentials stored in environment variables. (More features will be added in the future.) The following is a set of instructions to have Qodo Merge do a review of your CodeCommit pull request from the command line:
1. Create an IAM user that you will use to read CodeCommit pull requests and post comments
- Note: That user should have CLI access only, not Console access
2. Add IAM permissions to that user, to allow access to CodeCommit (see IAM Role example below)
3. Generate an Access Key for your IAM user
4. Set the Access Key and Secret using environment variables (see Access Key example below)
5. Set the `git_provider` value to `codecommit` in the `pr_agent/settings/configuration.toml` settings file
6. Set the `PYTHONPATH` to include your `pr-agent` project directory
- Option A: Add `PYTHONPATH="/PATH/TO/PROJECTS/pr-agent` to your `.env` file
- Option B: Set `PYTHONPATH` and run the CLI in one command, for example:
- `PYTHONPATH="/PATH/TO/PROJECTS/pr-agent python pr_agent/cli.py [--ARGS]`
---
#### AWS CodeCommit IAM Role Example
Example IAM permissions to that user to allow access to CodeCommit:
- Note: The following is a working example of IAM permissions that has read access to the repositories and write access to allow posting comments
- Note: If you only want pr-agent to review your pull requests, you can tighten the IAM permissions further, however this IAM example will work, and allow the pr-agent to post comments to the PR
- Note: You may want to replace the `"Resource": "*"` with your list of repos, to limit access to only those repos
```json
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": [
"codecommit:BatchDescribe*",
"codecommit:BatchGet*",
"codecommit:Describe*",
"codecommit:EvaluatePullRequestApprovalRules",
"codecommit:Get*",
"codecommit:List*",
"codecommit:PostComment*",
"codecommit:PutCommentReaction",
"codecommit:UpdatePullRequestDescription",
"codecommit:UpdatePullRequestTitle"
],
"Resource": "*"
}
]
}
```
#### AWS CodeCommit Access Key and Secret
Example setting the Access Key and Secret using environment variables
```sh
export AWS_ACCESS_KEY_ID="XXXXXXXXXXXXXXXX"
export AWS_SECRET_ACCESS_KEY="XXXXXXXXXXXXXXXX"
export AWS_DEFAULT_REGION="us-east-1"
```
#### AWS CodeCommit CLI Example
After you set up AWS CodeCommit using the instructions above, here is an example CLI run that tells pr-agent to **review** a given pull request.
(Replace your specific PYTHONPATH and PR URL in the example)
```sh
PYTHONPATH="/PATH/TO/PROJECTS/pr-agent" python pr_agent/cli.py \
--pr_url https://us-east-1.console.aws.amazon.com/codesuite/codecommit/repositories/MY_REPO_NAME/pull-requests/321 \
review
```

## Run as a GitLab Pipeline
You can use a pre-built Action Docker image to run PR-Agent as a GitLab pipeline. This is a simple way to get started with Qodo Merge without setting up your own server.
(1) Add the following file to your repository under `.gitlab-ci.yml`:
```yaml
stages:
- pr_agent
pr_agent_job:
stage: pr_agent
image:
name: codiumai/pr-agent:latest
entrypoint: [""]
script:
- cd /app
- echo "Running PR Agent action step"
- export MR_URL="$CI_MERGE_REQUEST_PROJECT_URL/merge_requests/$CI_MERGE_REQUEST_IID"
- echo "MR_URL=$MR_URL"
- export gitlab__url=$CI_SERVER_PROTOCOL://$CI_SERVER_FQDN
- export gitlab__PERSONAL_ACCESS_TOKEN=$GITLAB_PERSONAL_ACCESS_TOKEN
- export config__git_provider="gitlab"
- export openai__key=$OPENAI_KEY
- python -m pr_agent.cli --pr_url="$MR_URL" describe
- python -m pr_agent.cli --pr_url="$MR_URL" review
- python -m pr_agent.cli --pr_url="$MR_URL" improve
rules:
- if: '$CI_PIPELINE_SOURCE == "merge_request_event"'
```
This script will run Qodo Merge on every new merge request. You can modify the `rules` section to run Qodo Merge on different events.
You can also modify the `script` section to run different Qodo Merge commands, or with different parameters by exporting different environment variables.
(2) Add the following masked variables to your GitLab repository (CI/CD -> Variables):
- `GITLAB_PERSONAL_ACCESS_TOKEN`: Your GitLab personal access token.
- `OPENAI_KEY`: Your OpenAI key.
Note that if your base branches are not protected, don't set the variables as `protected`, since the pipeline will not have access to them.
> **Note**: The `$CI_SERVER_FQDN` variable is available starting from GitLab version 16.10. If you're using an earlier version, this variable will not be available. However, you can combine `$CI_SERVER_HOST` and `$CI_SERVER_PORT` to achieve the same result. Please ensure you're using a compatible version or adjust your configuration.
## Run a GitLab webhook server
1. In GitLab create a new user and give it "Reporter" role ("Developer" if using Pro version of the agent) for the intended group or project.
2. For the user from step 1. generate a `personal_access_token` with `api` access.
3. Generate a random secret for your app, and save it for later (`shared_secret`). For example, you can use:
```bash
SHARED_SECRET=$(python -c "import secrets; print(secrets.token_hex(10))")
```
4. Clone this repository:
```bash
git clone https://github.com/qodo-ai/pr-agent.git
```
5. Prepare variables and secrets. Skip this step if you plan on setting these as environment variables when running the agent:
1. In the configuration file/variables:
- Set `config.git_provider` to "gitlab"
2. In the secrets file/variables:
- Set your AI model key in the respective section
- In the [gitlab] section, set `personal_access_token` (with token from step 2) and `shared_secret` (with secret from step 3)
6. Build a Docker image for the app and optionally push it to a Docker repository. We'll use Dockerhub as an example:
```bash
docker build . -t gitlab_pr_agent --target gitlab_webhook -f docker/Dockerfile
docker push codiumai/pr-agent:gitlab_webhook # Push to your Docker repository
```
7. Set the environmental variables, the method depends on your docker runtime. Skip this step if you included your secrets/configuration directly in the Docker image.
```bash
CONFIG__GIT_PROVIDER=gitlab
GITLAB__PERSONAL_ACCESS_TOKEN=<personal_access_token>
GITLAB__SHARED_SECRET=<shared_secret>
GITLAB__URL=https://gitlab.com
OPENAI__KEY=<your_openai_api_key>
```
8. Create a webhook in your GitLab project. Set the URL to `http[s]://<PR_AGENT_HOSTNAME>/webhook`, the secret token to the generated secret from step 3, and enable the triggers `push`, `comments` and `merge request events`.
9. Test your installation by opening a merge request or commenting on a merge request using one of PR Agent's commands.

# Installation
## Self-hosted PR-Agent
There are several ways to use self-hosted PR-Agent:
- [Locally](./locally.md)
- [GitHub integration](./github.md)
- [GitLab integration](./gitlab.md)
- [BitBucket integration](./bitbucket.md)
- [Azure DevOps integration](./azure.md)
## Qodo Merge 💎
Qodo Merge, an app hosted by QodoAI for GitHub\GitLab\BitBucket, is also available.
<br>
With Qodo Merge, installation is as simple as adding the Qodo Merge app to your relevant repositories.
See [here](https://qodo-merge-docs.qodo.ai/installation/qodo_merge/) for more details.

View File

@ -1,158 +0,0 @@
To run PR-Agent locally, you first need to acquire two keys:
1. An OpenAI key from [here](https://platform.openai.com/api-keys){:target="_blank"}, with access to GPT-4 and o4-mini (or a key for other [language models](https://qodo-merge-docs.qodo.ai/usage-guide/changing_a_model/), if you prefer).
2. A personal access token from your Git platform (GitHub, GitLab, BitBucket) with repo scope. GitHub token, for example, can be issued from [here](https://github.com/settings/tokens){:target="_blank"}
## Using Docker image
A list of the relevant tools can be found in the [tools guide](../tools/).
To invoke a tool (for example `review`), you can run PR-Agent directly from the Docker image. Here's how:
- For GitHub:
```bash
docker run --rm -it -e OPENAI.KEY=<your key> -e GITHUB.USER_TOKEN=<your token> codiumai/pr-agent:latest --pr_url <pr_url> review
```
If you are using GitHub enterprise server, you need to specify the custom url as variable.
For example, if your GitHub server is at `https://github.mycompany.com`, add the following to the command:
```bash
-e GITHUB.BASE_URL=https://github.mycompany.com/api/v3
```
- For GitLab:
```bash
docker run --rm -it -e OPENAI.KEY=<your key> -e CONFIG.GIT_PROVIDER=gitlab -e GITLAB.PERSONAL_ACCESS_TOKEN=<your token> codiumai/pr-agent:latest --pr_url <pr_url> review
```
If you have a dedicated GitLab instance, you need to specify the custom url as variable:
```bash
-e GITLAB.URL=<your gitlab instance url>
```
- For BitBucket:
```bash
docker run --rm -it -e CONFIG.GIT_PROVIDER=bitbucket -e OPENAI.KEY=$OPENAI_API_KEY -e BITBUCKET.BEARER_TOKEN=$BITBUCKET_BEARER_TOKEN codiumai/pr-agent:latest --pr_url=<pr_url> review
```
For other git providers, update `CONFIG.GIT_PROVIDER` accordingly and check the [`pr_agent/settings/.secrets_template.toml`](https://github.com/Codium-ai/pr-agent/blob/main/pr_agent/settings/.secrets_template.toml) file for environment variables expected names and values.
### Utilizing environment variables
It is also possible to provide or override the configuration by setting the corresponding environment variables.
You can define the corresponding environment variables by following this convention: `<TABLE>__<KEY>=<VALUE>` or `<TABLE>.<KEY>=<VALUE>`.
The `<TABLE>` refers to a table/section in a configuration file and `<KEY>=<VALUE>` refers to the key/value pair of a setting in the configuration file.
For example, suppose you want to run `pr_agent` that connects to a self-hosted GitLab instance similar to an example above.
You can define the environment variables in a plain text file named `.env` with the following content:
```bash
CONFIG__GIT_PROVIDER="gitlab"
GITLAB__URL="<your url>"
GITLAB__PERSONAL_ACCESS_TOKEN="<your token>"
OPENAI__KEY="<your key>"
```
Then, you can run `pr_agent` using Docker with the following command:
```shell
docker run --rm -it --env-file .env codiumai/pr-agent:latest <tool> <tool parameter>
```
---
### I get an error when running the Docker image. What should I do?
If you encounter an error when running the Docker image, it is almost always due to a misconfiguration of api keys or tokens.
Note that litellm, which is used by pr-agent, sometimes returns non-informative error messages such as `APIError: OpenAIException - Connection error.`
Carefully check the api keys and tokens you provided and make sure they are correct.
Adjustments may be needed depending on your llm provider.
For example, for Azure OpenAI, additional keys are [needed](https://qodo-merge-docs.qodo.ai/usage-guide/changing_a_model/#azure).
Same goes for other providers, make sure to check the [documentation](https://qodo-merge-docs.qodo.ai/usage-guide/changing_a_model/#changing-a-model)
## Using pip package
Install the package:
```bash
pip install pr-agent
```
Then run the relevant tool with the script below.
<br>
Make sure to fill in the required parameters (`user_token`, `openai_key`, `pr_url`, `command`):
```python
from pr_agent import cli
from pr_agent.config_loader import get_settings
def main():
# Fill in the following values
provider = "github" # github/gitlab/bitbucket/azure_devops
user_token = "..." # user token
openai_key = "..." # OpenAI key
pr_url = "..." # PR URL, for example 'https://github.com/Codium-ai/pr-agent/pull/809'
command = "/review" # Command to run (e.g. '/review', '/describe', '/ask="What is the purpose of this PR?"', ...)
# Setting the configurations
get_settings().set("CONFIG.git_provider", provider)
get_settings().set("openai.key", openai_key)
get_settings().set("github.user_token", user_token)
# Run the command. Feedback will appear in GitHub PR comments
cli.run_command(pr_url, command)
if __name__ == '__main__':
main()
```
## Run from source
1. Clone this repository:
```bash
git clone https://github.com/Codium-ai/pr-agent.git
```
2. Navigate to the `/pr-agent` folder and install the requirements in your favorite virtual environment:
```bash
pip install -e .
```
*Note: If you get an error related to Rust in the dependency installation then make sure Rust is installed and in your `PATH`, instructions: https://rustup.rs*
3. Copy the secrets template file and fill in your OpenAI key and your GitHub user token:
```bash
cp pr_agent/settings/.secrets_template.toml pr_agent/settings/.secrets.toml
chmod 600 pr_agent/settings/.secrets.toml
# Edit .secrets.toml file
```
4. Run the cli.py script:
```bash
python3 -m pr_agent.cli --pr_url <pr_url> review
python3 -m pr_agent.cli --pr_url <pr_url> ask <your question>
python3 -m pr_agent.cli --pr_url <pr_url> describe
python3 -m pr_agent.cli --pr_url <pr_url> improve
python3 -m pr_agent.cli --pr_url <pr_url> add_docs
python3 -m pr_agent.cli --pr_url <pr_url> generate_labels
python3 -m pr_agent.cli --issue_url <issue_url> similar_issue
...
```

<figure markdown="1">
![Step 1](https://www.codium.ai/images/pr_agent/gitlab_pro_pat.png){width=750}
</figure>
Store the token in a safe place, you wont be able to access it again after it was generated.
#### Step 2
Generate a shared secret and link it to the access token. Browse to [https://register.gitlab.pr-agent.codium.ai](https://register.gitlab.pr-agent.codium.ai).
Fill in your generated GitLab token and your company or personal name in the appropriate fields and click "Submit".
You should see "Success!" displayed above the Submit button, and a shared secret will be generated. Store it in a safe place, you wont be able to access it again after it was generated.
#### Step 3
Install a webhook for your repository or groups, by clicking “webhooks” on the settings menu. Click the “Add new webhook” button.
<figure markdown="1">

# Qodo Merge Pull Request Benchmark
## Methodology
Qodo Merge PR Benchmark evaluates and compares the performance of two Large Language Models (LLMs) in analyzing pull request code and providing meaningful code suggestions.
Our diverse dataset comprises of 400 pull requests from over 100 repositories, spanning various programming languages and frameworks to reflect real-world scenarios.
- For each pull request, two distinct LLMs process the same prompt using the Qodo Merge `improve` tool, each generating two sets of responses. The prompt for response generation can be found [here](https://github.com/qodo-ai/pr-agent/blob/main/pr_agent/settings/code_suggestions/pr_code_suggestions_prompts_not_decoupled.toml).
- Subsequently, a high-performing third model (an AI judge) evaluates the responses from the initial two models to determine the superior one. We utilize OpenAI's `o3` model as the judge, though other models have yielded consistent results. The prompt for this comparative judgment is available [here](https://github.com/Codium-ai/pr-agent-settings/tree/main/benchmark).
- We aggregate comparison outcomes across all the pull requests, calculating the win rate for each model. We also analyze the qualitative feedback (the "why" explanations from the judge) to identify each model's comparative strengths and weaknesses.
This approach provides not just a quantitative score but also a detailed analysis of each model's strengths and weaknesses.
- For each model we build a "Model Card", comparing it against others. To ensure full transparency and enable community scrutiny, we also share the raw code suggestions generated by each model, and the judge's specific feedback. See example for the full output [here](https://github.com/Codium-ai/pr-agent-settings/blob/main/benchmark/sonnet_37_vs_gemini-2.5-pro-preview-05-06.md)
Note that this benchmark focuses on quality: the ability of an LLM to process complex pull request with multiple files and nuanced task to produce high-quality code suggestions.
Other factors like speed, cost, and availability, while also relevant for model selection, are outside this benchmark's scope.
## TL;DR
Here's a summary of the win rates based on the benchmark:
[//]: # (| Model A | Model B | Model A Win Rate | Model B Win Rate |)
[//]: # (|:-------------------------------|:-------------------------------|:----------------:|:----------------:|)
[//]: # (| Gemini-2.5-pro-preview-05-06 | GPT-4.1 | 70.4% | 29.6% |)
[//]: # (| Gemini-2.5-pro-preview-05-06 | Sonnet 3.7 | 78.1% | 21.9% |)
[//]: # (| GPT-4.1 | Sonnet 3.7 | 61.0% | 39.0% |)

#### Analysis Summary
Model 'Gemini-2.5-pro-preview-05-06' is generally more useful thanks to wider and more accurate bug detection and concrete patches, but it sacrifices compliance discipline and sometimes oversteps the task rules. Model 'GPT-4.1' is safer and highly rule-abiding, yet often too timid—missing many genuine issues and providing limited insight. An ideal reviewer would combine 'GPT-4.1 restraint with 'Gemini-2.5-pro-preview-05-06' thoroughness.
#### Detailed Analysis
Gemini-2.5-pro-preview-05-06 strengths:
- better_bug_coverage: Detects and explains more critical issues, winning in ~70 % of comparisons and achieving a higher average score.
- actionable_fixes: Supplies clear code snippets, correct language labels, and often multiple coherent suggestions per diff.
- deeper_reasoning: Shows stronger grasp of logic, edge cases, and cross-file implications, leading to broader, high-impact reviews.
Gemini-2.5-pro-preview-05-06 weaknesses:
- guideline_violations: More prone to over-eager advice—non-critical tweaks, touching unchanged code, suggesting new imports, or minor format errors.
- occasional_overreach: Some fixes are speculative or risky, potentially introducing new bugs.
- redundant_or_duplicate: At times repeats the same point or exceeds the required brevity.
### Comparison against Sonnet 3.7
![Comparison](https://codium.ai/images/qodo_merge_benchmark/sonnet_37_vs_gemini-2.5-pro-preview-05-06_judge_o3.png){width=768}
#### Analysis Summary
Model 'Gemini-2.5-pro-preview-05-06' is the stronger reviewer—more frequently identifies genuine, high-impact bugs and provides well-formed, actionable fixes. Model 'Sonnet 3.7' is safer against false positives and tends to be concise but often misses important defects or offers low-value or incorrect suggestions.
See raw results [here](https://github.com/Codium-ai/pr-agent-settings/blob/main/benchmark/sonnet_37_vs_gemini-2.5-pro-preview-05-06.md)
#### Detailed Analysis
Gemini-2.5-pro-preview-05-06 strengths:
- higher_accuracy_and_coverage: finds real critical bugs and supplies actionable patches in most examples (better in 78 % of cases).
- guideline_awareness: usually respects new-lines-only scope, ≤3 suggestions, proper YAML, and stays silent when no issues exist.
- detailed_reasoning_and_patches: explanations tie directly to the diff and fixes are concrete, often catching multiple related defects that 'Sonnet 3.7' overlooks.
Gemini-2.5-pro-preview-05-06 weaknesses:
- occasional_rule_violations: sometimes proposes new imports, package-version changes, or edits outside the added lines.
- overzealous_suggestions: may add speculative or stylistic fixes that exceed the “critical” scope, or mis-label severity.
- sporadic_technical_slips: a few patches contain minor coding errors, oversized snippets, or duplicate/contradicting advice.
## GPT-4.1 - Model Card
### Comparison against Sonnet 3.7
![Comparison](https://codium.ai/images/qodo_merge_benchmark/gpt-4.1_vs_sonnet_3.7_judge_o3.png){width=768}
#### Analysis Summary
Model 'GPT-4.1' is safer and more compliant, preferring silence over speculation, which yields fewer rule breaches and false positives but misses some real bugs.
Model 'Sonnet 3.7' is more adventurous and often uncovers important issues that 'GPT-4.1' ignores, yet its aggressive style leads to frequent guideline violations and a higher proportion of incorrect or non-critical advice.
See raw results [here](https://github.com/Codium-ai/pr-agent-settings/blob/main/benchmark/gpt-4.1_vs_sonnet_3.7_judge_o3.md)
#### Detailed Analysis
GPT-4.1 strengths:
- Strong guideline adherence: usually stays strictly on `+` lines, avoids non-critical or stylistic advice, and rarely suggests forbidden imports; often outputs an empty list when no real bug exists.
- Lower false-positive rate: suggestions are more accurate and seldom introduce new bugs; fixes compile more reliably.
- Good schema discipline: YAML is almost always well-formed and fields are populated correctly.
GPT-4.1 weaknesses:
- Misses bugs: often returns an empty list even when a clear critical issue is present, so coverage is narrower.
- Sparse feedback: when it does comment, it tends to give fewer suggestions and sometimes lacks depth or completeness.
- Occasional metadata/slip-ups (wrong language tags, overly broad code spans), though less harmful than Sonnet 3.7 errors.

## Overview
The `analyze` tool combines advanced static code analysis with LLM capabilities to provide a comprehensive analysis of the PR code changes.
The tool scans the PR code changes, finds the code components (methods, functions, classes) that changed, and enables to interactively generate tests, docs, code suggestions and similar code search for each component.
It can be invoked manually by commenting on any PR:
```
/analyze
```
## Example usage
An example result:
![Analyze 1](https://codium.ai/images/pr_agent/analyze_1.png){width=750}
!!! note "Language that are currently supported:"
Python, Java, C++, JavaScript, TypeScript, C#.

## Overview
The `ask` tool answers questions about the PR, based on the PR code changes. Make sure to be specific and clear in your questions.
It can be invoked manually by commenting on any PR:
```
/ask "..."
```
## Example usage
![Ask Comment](https://codium.ai/images/pr_agent/ask_comment.png){width=512}
![Ask](https://codium.ai/images/pr_agent/ask.png){width=512}
## Ask lines
You can run `/ask` on specific lines of code in the PR from the PR's diff view. The tool will answer questions based on the code changes in the selected lines.
- Click on the '+' sign next to the line number to select the line.
- To select multiple lines, click on the '+' sign of the first line and then hold and drag to select the rest of the lines.
- write `/ask "..."` in the comment box and press `Add single comment` button.
![Ask Line](https://codium.ai/images/pr_agent/Ask_line.png){width=512}
Note that the tool does not have "memory" of previous questions, and answers each question independently.
## Ask on images
You can also ask questions about images that appear in the comment, where the entire PR code will be used as context.
<br>
The basic syntax is:
```
/ask "..."
[Image](https://real_link_to_image)
```
where `https://real_link_to_image` is the direct link to the image.
Note that GitHub has a built-in mechanism of pasting images in comments. However, pasted image does not provide a direct link.
To get a direct link to an image, we recommend using the following scheme:
1\. First, post a comment that contains **only** the image:
![Ask image1](https://codium.ai/images/pr_agent/ask_images1.png){width=512}
2\. Quote reply to that comment:
![Ask image2](https://codium.ai/images/pr_agent/ask_images2.png){width=512}
3\. In the screen opened, type the question below the image:
![Ask image3](https://codium.ai/images/pr_agent/ask_images3.png){width=512}
![Ask image4](https://codium.ai/images/pr_agent/ask_images4.png){width=512}
4\. Post the comment, and receive the answer:
![Ask image5](https://codium.ai/images/pr_agent/ask_images5.png){width=512}

## Overview
The CI feedback tool (`/checks)` automatically triggers when a PR has a failed check.
The tool analyzes the failed checks and provides several feedbacks:
- Failed stage
- Failed test name
- Failure summary
- Relevant error logs
## Example usage
![Failed Check 1](https://www.codium.ai/images/pr_agent/failed_check1.png){width=768}
&rarr;
![Failed Check 2](https://www.codium.ai/images/pr_agent/failed_check2.png){width=768}
___
In addition to being automatically triggered, the tool can also be invoked manually by commenting on a PR:
```
/checks "https://github.com/{repo_name}/actions/runs/{run_number}/job/{job_number}"
```
where `{repo_name}` is the name of the repository, `{run_number}` is the run number of the failed check, and `{job_number}` is the job number of the failed check.
## Disabling the tool from running automatically
If you wish to disable the tool from running automatically, you can do so by adding the following configuration to the configuration file:
```
[checks]
enable_auto_checks_feedback = false
```
## Configuration options
- `enable_auto_checks_feedback` - if set to true, the tool will automatically provide feedback when a check is failed. Default is true.
- `excluded_checks_list` - a list of checks to exclude from the feedback, for example: ["check1", "check2"]. Default is an empty list.
- `persistent_comment` - if set to true, the tool will overwrite a previous checks comment with the new feedback. Default is true.
- `enable_help_text=true` - if set to true, the tool will provide a help message when a user comments "/checks" on a PR. Default is true.
- `final_update_message` - if `persistent_comment` is true and updating a previous checks message, the tool will also create a new message: "Persistent checks updated to latest commit". Default is true.

## Overview
The `generate_labels` tool scans the PR code changes, and given a list of labels and their descriptions, it automatically suggests labels that match the PR code changes.
It can be invoked manually by commenting on any PR:
```
/generate_labels
```
## Example usage
If we wish to add detect changes to SQL queries in a given PR, we can add the following custom label along with its description:
![Custom labels list](https://codium.ai/images/pr_agent/custom_labels_list.png){width=768}
When running the `generate_labels` tool on a PR that includes changes in SQL queries, it will automatically suggest the custom label:
![Custom labels published](https://codium.ai/images/pr_agent/custom_label_published.png){width=768}
Note that in addition to the dedicated tool `generate_labels`, the custom labels will also be used by the `describe` tool.
### How to enable custom labels
There are 3 ways to enable custom labels:
#### 1. CLI (local configuration file)
When working from CLI, you need to apply the [configuration changes](#configuration-options) to the [custom_labels file](https://github.com/Codium-ai/pr-agent/blob/main/pr_agent/settings/custom_labels.toml):
#### 2. Repo configuration file
To enable custom labels, you need to apply the [configuration changes](#configuration-options) to the local `.pr_agent.toml` file in your repository.
#### 3. Handle custom labels from the Repo's labels page 💎
> This feature is available only in Qodo Merge
* GitHub : `https://github.com/{owner}/{repo}/labels`, or click on the "Labels" tab in the issues or PRs page.
* GitLab : `https://gitlab.com/{owner}/{repo}/-/labels`, or click on "Manage" -> "Labels" on the left menu.
b. Add/edit the custom labels. It should be formatted as follows:
* Label name: The name of the custom label.
* Description: Start the description of with prefix `pr_agent:`, for example: `pr_agent: Description of when AI should suggest this label`.<br>
The description should be comprehensive and detailed, indicating when to add the desired label.
![Add native custom labels](https://codium.ai/images/pr_agent/add_native_custom_labels.png){width=880}
c. Now the custom labels will be included in the `generate_labels` tool.
> This feature is supported in GitHub and GitLab.
## Configuration options
* Change `enable_custom_labels` to True: This will turn off the default labels and enable the custom labels provided in the custom_labels.toml file.
* Add the custom labels. It should be formatted as follows:
```
[config]
enable_custom_labels=true
[custom_labels."Custom Label Name"]
description = "Description of when AI should suggest this label"
[custom_labels."Custom Label 2"]
description = "Description of when AI should suggest this label 2"
```

## Overview
The `custom_prompt` tool scans the PR code changes, and automatically generates suggestions for improving the PR code.
It shares similarities with the `improve` tool, but with one main difference: the `custom_prompt` tool will **only propose suggestions that follow specific guidelines defined by the prompt** in: `pr_custom_prompt.prompt` configuration.
The tool can be triggered [automatically](../usage-guide/automations_and_usage.md#github-app-automatic-tools-when-a-new-pr-is-opened) every time a new PR is opened, or can be invoked manually by commenting on a PR.
When commenting, use the following template:
```
/custom_prompt --pr_custom_prompt.prompt="
The code suggestions should focus only on the following:
- ...
- ...
"
```
With a [configuration file](../usage-guide/automations_and_usage.md#github-app), use the following template:
```toml
[pr_custom_prompt]
prompt="""\
The suggestions should focus only on the following:
-...
-...
"""
```
Remember - with this tool, you are the prompter. Be specific, clear, and concise in the instructions. Specify relevant aspects that you want the model to focus on. \
You might benefit from several trial-and-error iterations, until you get the correct prompt for your use case.
## Example usage
Here is an example of a possible prompt, defined in the configuration file:
```toml
[pr_custom_prompt]
prompt="""\
The code suggestions should focus only on the following:
- look for edge cases when implementing a new function
- make sure every variable has a meaningful name
- make sure the code is efficient
"""
```
(The instructions above are just an example. We want to emphasize that the prompt should be specific and clear, and be tailored to the needs of your project)
Results obtained with the prompt above:
![Custom prompt results](https://codium.ai/images/pr_agent/custom_suggestions_result.png){width=768}
## Configuration options
- `prompt`: the prompt for the tool. It should be a multi-line string.
- `num_code_suggestions_per_chunk`: number of code suggestions provided by the 'custom_prompt' tool, per chunk. Default is 3.
- `enable_help_text`: if set to true, the tool will display a help text in the comment. Default is true.

/describe
```
## Example usage
### Manual triggering
Invoke the tool manually by commenting `/describe` on any PR:
![Describe comment](https://codium.ai/images/pr_agent/describe_comment.png){width=512}
After ~30 seconds, the tool will generate a description for the PR:
![Describe New](https://codium.ai/images/pr_agent/describe_new.png){width=512}
If you want to edit [configurations](#configuration-options), add the relevant ones to the command:
```
/describe --pr_description.some_config1=... --pr_description.some_config2=...
```
### Automatic triggering
To run the `describe` automatically when a PR is opened, define in a [configuration file](https://qodo-merge-docs.qodo.ai/usage-guide/configuration_options/#wiki-configuration-file):
```
[github_app]
pr_commands = [
"/describe",
...
]
[pr_description]
publish_labels = true
...
```
- The `pr_commands` lists commands that will be executed automatically when a PR is opened.
- The `[pr_description]` section contains the configurations for the `describe` tool you want to edit (if any).
## Preserving the original user description
By default, Qodo Merge preserves your original PR description by placing it above the generated content.
This requires including your description during the initial PR creation.
Be aware that if you edit the description while the automated tool is running, a race condition may occur, potentially causing your original description to be lost.
When updating PR descriptions, the `/describe` tool considers everything above the "PR Type" field as user content and will preserve it.
Everything below this marker is treated as previously auto-generated content and will be replaced.

## Inline file summary 💎
This feature enables you to copy the `changes walkthrough` table to the "Files changed" tab, so you can quickly understand the changes in each file while reviewing the code changes (diff view).
To copy the `changes walkthrough` table to the "Files changed" tab, you can click on the checkbox that appears PR Description status message below the main PR Description:
![Add table checkbox](https://codium.ai/images/pr_agent/add_table_checkbox.png){width=512}
If you prefer to have the file summaries appear in the "Files changed" tab on every PR, change the `pr_description.inline_file_summary` parameter in the configuration file, possible values are:
- `'table'`: File changes walkthrough table will be displayed on the top of the "Files changed" tab, in addition to the "Conversation" tab.
![Diffview table](https://codium.ai/images/pr_agent/diffview-table.png){width=512}
- `true`: A collapsible file comment with changes title and a changes summary for each file in the PR.
![Diffview changes](https://codium.ai/images/pr_agent/diffview_changes.png){width=512}
- `false` (`default`): File changes walkthrough will be added only to the "Conversation" tab.
**Note**: that this feature is currently available only for GitHub.
## Markers template
To enable markers, set `pr_description.use_description_markers=true`.
Markers enable to easily integrate user's content and auto-generated content, with a template-like mechanism.
For example, if the PR original description was:
```
User content...
## PR Type:
pr_agent:type
## PR Description:
pr_agent:summary
## PR Walkthrough:
pr_agent:walkthrough
```
The marker `pr_agent:type` will be replaced with the PR type, `pr_agent:summary` will be replaced with the PR summary, and `pr_agent:walkthrough` will be replaced with the PR walkthrough.
![Describe markers before](https://codium.ai/images/pr_agent/describe_markers_before.png){width=512}
becomes
![Describe markers after](https://codium.ai/images/pr_agent/describe_markers_after.png){width=512}
**Configuration params**:
- `use_description_markers`: if set to true, the tool will use markers template. It replaces every marker of the form `pr_agent:marker_name` with the relevant content. Default is false.
- `include_generated_by_header`: if set to true, the tool will add a dedicated header: 'Generated by PR Agent at ...' to any automatic content. Default is true.
## Custom labels
The default labels of the describe tool are quite generic, since they are meant to be used in any repo: [`Bug fix`, `Tests`, `Enhancement`, `Documentation`, `Other`].
You can define custom labels that are relevant for your repo and use cases.
Custom labels can be defined in a [configuration file](https://qodo-merge-docs.qodo.ai/tools/custom_labels/#configuration-options), or directly in the repo's [labels page](#handle-custom-labels-from-the-repos-labels-page).
Make sure to provide proper title, and a detailed and well-phrased description for each label, so the tool will know when to suggest it.
Each label description should be a **conditional statement**, that indicates if to add the label to the PR or not, according to the PR content.
### Handle custom labels from a configuration file
Example for a custom labels configuration setup in a configuration file:
```
[config]
enable_custom_labels=true
[custom_labels."sql_changes"]
description = "Use when a PR contains changes to SQL queries"
[custom_labels."test"]
description = "use when a PR primarily contains new tests"
...
```
### Handle custom labels from the Repo's labels page 💎
You can also control the custom labels that will be suggested by the `describe` tool from the repo's labels page:
- GitHub : go to `https://github.com/{owner}/{repo}/labels` (or click on the "Labels" tab in the issues or PRs page)
- GitLab : go to `https://gitlab.com/{owner}/{repo}/-/labels` (or click on "Manage" -> "Labels" on the left menu)
Now add/edit the custom labels. they should be formatted as follows:
- Label name: The name of the custom label.
- Description: Start the description of with prefix `pr_agent:`, for example: `pr_agent: Description of when AI should suggest this label`.<br>
Examples for custom labels:
- `Main topic:performance` - pr_agent:The main topic of this PR is performance
- `New endpoint` - pr_agent:A new endpoint was added in this PR
- `SQL query` - pr_agent:A new SQL query was added in this PR
- `Dockerfile changes` - pr_agent:The PR contains changes in the Dockerfile
- ...
The description should be comprehensive and detailed, indicating when to add the desired label. For example:
![Add native custom labels](https://codium.ai/images/pr_agent/add_native_custom_labels.png){width=768}
## Usage Tips
!!! tip "Automation"
- When you first install Qodo Merge app, the [default mode](../usage-guide/automations_and_usage.md#github-app) for the describe tool is:
```
pr_commands = ["/describe", ...]
```
meaning the `describe` tool will run automatically on every PR, with the default configurations.
- Markers are an alternative way to control the generated description, to give maximal control to the user. If you set:
```
pr_commands = ["/describe --pr_description.use_description_markers=true", ...]
```
the tool will replace every marker of the form `pr_agent:marker_name` in the PR description with the relevant content, where `marker_name` is one of the following:
*`type`: the PR type.
* `summary`: the PR summary.
* `walkthrough`: the PR walkthrough.
- Note that when markers are enabled, if the original PR description does not contain any markers, the tool will not alter the description at all.

You can state a name of a specific component in the PR to get documentation only for that component:
```
/add_docs component_name
```
## Configuration options
- `docs_style`: The exact style of the documentation (for python docstring). you can choose between: `google`, `numpy`, `sphinx`, `restructuredtext`, `plain`. Default is `sphinx`.
- `extra_instructions`: Optional extra instructions to the tool. For example: "focus on the changes in the file X. Ignore change in ...".
!!! note "Notes"
- The following languages are currently supported: Python, Java, C++, JavaScript, TypeScript, C#.
- This tool can also be triggered interactively by using the [`analyze`](./analyze.md) tool.

## Overview
The `help_docs` tool can answer a free-text question based on a git documentation folder.
It can be invoked manually by commenting on any PR or Issue:
```
/help_docs "..."
```
Or configured to be triggered automatically when a [new issue is opened](#run-as-a-github-action).
The tool assumes by default that the documentation is located in the root of the repository, at `/docs` folder.
However, this can be customized by setting the `docs_path` configuration option:
```toml
[pr_help_docs]
repo_url = "" # The repository to use as context
docs_path = "docs" # The documentation folder
repo_default_branch = "main" # The branch to use in case repo_url overwritten
```
See more configuration options in the [Configuration options](#configuration-options) section.
## Example usage
[//]: # (#### Asking a question about this repository:)

**Response**:
![help_docs response](https://codium.ai/images/pr_agent/help_docs_response.png){width=512}
## Run automatically when a new issue is opened
You can configure PR-Agent to run `help_docs` automatically on any newly created issue.
This can be useful, for example, for providing immediate feedback to users who open issues with questions on open-source projects with extensive documentation.
Here's how:
1) Follow the steps depicted under [Run as a Github Action](https://qodo-merge-docs.qodo.ai/installation/github/#run-as-a-github-action) to create a new workflow, such as:`.github/workflows/help_docs.yml`:
2) Edit your yaml file to the following:
```yaml
name: Run pr agent on every opened issue, respond to user comments on an issue
#When the action is triggered
on:
issues:
types: [opened] #New issue
# Read env. variables
env:
GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
GITHUB_API_URL: ${{ github.api_url }}
GIT_REPO_URL: ${{ github.event.repository.clone_url }}
ISSUE_URL: ${{ github.event.issue.html_url || github.event.comment.html_url }}
ISSUE_BODY: ${{ github.event.issue.body || github.event.comment.body }}
OPENAI_KEY: ${{ secrets.OPENAI_KEY }}
# The actual set of actions
jobs:
issue_agent:
runs-on: ubuntu-latest
if: ${{ github.event.sender.type != 'Bot' }} #Do not respond to bots
# Set required permissions
permissions:
contents: read # For reading repository contents
issues: write # For commenting on issues
steps:
- name: Run PR Agent on Issues
if: ${{ env.ISSUE_URL != '' }}
uses: docker://codiumai/pr-agent:latest
with:
entrypoint: /bin/bash #Replace invoking cli.py directly with a shell
args: |
-c "cd /app && \
echo 'Running Issue Agent action step on ISSUE_URL=$ISSUE_URL' && \
export config__git_provider='github' && \
export github__user_token=$GITHUB_TOKEN && \
export github__base_url=$GITHUB_API_URL && \
export openai__key=$OPENAI_KEY && \
python -m pr_agent.cli --issue_url=$ISSUE_URL --pr_help_docs.repo_url="..." --pr_help_docs.docs_path="..." --pr_help_docs.openai_key=$OPENAI_KEY && \help_docs \"$ISSUE_BODY\""
```
3) Following completion of the remaining steps (such as adding secrets and relevant configurations, such as `repo_url` and `docs_path`) merge this change to your main branch.
When a new issue is opened, you should see a comment from `github-actions` bot with an auto response, assuming the question is related to the documentation of the repository.
---
## Configuration options
Under the section `pr_help_docs`, the [configuration file](https://github.com/Codium-ai/pr-agent/blob/main/pr_agent/settings/configuration.toml#L50) contains options to customize the 'help docs' tool:
- `repo_url`: If not overwritten, will use the repo from where the context came from (issue or PR), otherwise - use the given repo as context.
- `repo_default_branch`: The branch to use in case repo_url overwritten, otherwise - has no effect.
- `docs_path`: Relative path from root of repository (either the one this PR has been issued for, or above repo url).
- `exclude_root_readme`: Whether or not to exclude the root README file for querying the model.
- `supported_doc_exts` : Which file extensions should be included for the purpose of querying the model.

`Platforms supported: GitHub, GitLab, Bitbucket`
## Overview
The `implement` tool converts human code review discussions and feedback into ready-to-commit code changes.
It leverages LLM technology to transform PR comments and review suggestions into concrete implementation code, helping developers quickly turn feedback into working solutions.
## Usage Scenarios
### For Reviewers
Reviewers can request code changes by:
1. Selecting the code block to be modified.
2. Adding a comment with the syntax:
```
/implement <code-change-description>
```
![implement1](https://codium.ai/images/pr_agent/implement1.png){width=640}
### For PR Authors
PR authors can implement suggested changes by replying to a review comment using either: <br>
1. Add specific implementation details as described above
```
/implement <code-change-description>
```
2. Use the original review comment as instructions
```
/implement
```
![implement2](https://codium.ai/images/pr_agent/implement2.png){width=640}
### For Referencing Comments
You can reference and implement changes from any comment by:
```
/implement <link-to-review-comment>
```
![implement3](https://codium.ai/images/pr_agent/implement3.png){width=640}
Note that the implementation will occur within the review discussion thread.
**Configuration options**
- Use `/implement` to implement code change within and based on the review discussion.
- Use `/implement <code-change-description>` inside a review discussion to implement specific instructions.
- Use `/implement <link-to-review-comment>` to indirectly call the tool from any comment.

## Overview
The `improve` tool scans the PR code changes, and automatically generates meaningful suggestions for improving the PR code.
The tool can be triggered automatically every time a new PR is [opened](../usage-guide/automations_and_usage.md#github-app-automatic-tools-when-a-new-pr-is-opened), or it can be invoked manually by commenting on any PR:
```toml
/improve
```
## How it looks
=== "Suggestions Overview"
![code_suggestions_as_comment_closed](https://codium.ai/images/pr_agent/code_suggestions_as_comment_closed.png){width=512}
=== "Selecting a specific suggestion"
![code_suggestions_as_comment_open](https://codium.ai/images/pr_agent/code_suggestions_as_comment_open.png){width=512}
___
!!! note "The following features are available only for Qodo Merge 💎 users:"
- The `Apply / Chat` checkbox, which interactively converts a suggestion into a committable code comment
- The `More` checkbox to generate additional suggestions
- On Bitbucket (Cloud & Data Center) and GitLab Server (v16 and earlier), you can invoke [More Suggestions manually](#manual-more-suggestions)
## Example usage
### Manual triggering
Invoke the tool manually by commenting `/improve` on any PR. The code suggestions by default are presented as a single comment:
To edit [configurations](#configuration-options) related to the `improve` tool, use the following template:
```toml
/improve --pr_code_suggestions.some_config1=... --pr_code_suggestions.some_config2=...
```
For example, you can choose to present all the suggestions as committable code comments, by running the following command:
```toml
/improve --pr_code_suggestions.commitable_code_suggestions=true
```
![improve](https://codium.ai/images/pr_agent/improve.png){width=512}
As can be seen, a single table comment has a significantly smaller PR footprint. We recommend this mode for most cases.
Also note that collapsible are not supported in _Bitbucket_. Hence, the suggestions can only be presented in Bitbucket as code comments.
#### Manual more suggestions
To generate more suggestions (distinct from the ones already generated), for git-providers that don't support interactive checkbox option, you can manually run:
```
/improve --more_suggestions=true
```
### Automatic triggering
To run the `improve` automatically when a PR is opened, define in a [configuration file](https://qodo-merge-docs.qodo.ai/usage-guide/configuration_options/#wiki-configuration-file):
```toml
[github_app]
pr_commands = [
"/improve",
...
]
[pr_code_suggestions]
num_code_suggestions_per_chunk = ...
...
```
- The `pr_commands` lists commands that will be executed automatically when a PR is opened.
- The `[pr_code_suggestions]` section contains the configurations for the `improve` tool you want to edit (if any)
### Assessing Impact
>`💎 feature`
Qodo Merge tracks two types of implementations for tracking implemented suggestions:
- Direct implementation - when the user directly applies the suggestion by clicking the `Apply` checkbox.
- Indirect implementation - when the user implements the suggestion in their IDE environment. In this case, Qodo Merge will utilize, after each commit, a dedicated logic to identify if a suggestion was implemented, and will mark it as implemented.
![code_suggestions_assess_impact](https://codium.ai/images/pr_agent/code_suggestions_asses_impact.png){width=512}
In post-process, Qodo Merge counts the number of suggestions that were implemented, and provides general statistics and insights about the suggestions' impact on the PR process.
![code_suggestions_assess_impact_stats_1](https://codium.ai/images/pr_agent/code_suggestions_asses_impact_stats_1.png){width=512}
![code_suggestions_assess_impact_stats_2](https://codium.ai/images/pr_agent/code_suggestions_asses_impact_stats_2.png){width=512}
## Suggestion tracking
>`💎 feature. Platforms supported: GitHub, GitLab`
Qodo Merge employs a novel detection system to automatically [identify](https://qodo-merge-docs.qodo.ai/core-abilities/impact_evaluation/) AI code suggestions that PR authors have accepted and implemented.
Accepted suggestions are also automatically documented in a dedicated wiki page called `.pr_agent_accepted_suggestions`, allowing users to track historical changes, assess the tool's effectiveness, and learn from previously implemented recommendations in the repository.
An example [result](https://github.com/Codium-ai/pr-agent/wiki/.pr_agent_accepted_suggestions):
[![pr_agent_accepted_suggestions1.png](https://qodo.ai/images/pr_agent/pr_agent_accepted_suggestions1.png){width=768}](https://github.com/Codium-ai/pr-agent/wiki/.pr_agent_accepted_suggestions)
This dedicated wiki page will also serve as a foundation for future AI model improvements, allowing it to learn from historically implemented suggestions and generate more targeted, contextually relevant recommendations.
This feature is controlled by a boolean configuration parameter: `pr_code_suggestions.wiki_page_accepted_suggestions` (default is true).
!!! note "Wiki must be enabled"
While the aggregation process is automatic, GitHub repositories require a one-time manual wiki setup.
To initialize the wiki: navigate to `Wiki`, select `Create the first page`, then click `Save page`.
![pr_agent_accepted_suggestions_create_first_page.png](https://qodo.ai/images/pr_agent/pr_agent_accepted_suggestions_create_first_page.png){width=768}
Once a wiki repo is created, the tool will automatically use this wiki for tracking suggestions.
!!! note "Why a wiki page?"
Your code belongs to you, and we respect your privacy. Hence, we won't store any code suggestions in an external database.
Instead, we leverage a dedicated private page, within your repository wiki, to track suggestions. This approach offers convenient secure suggestion tracking while avoiding pull requests or any noise to the main repository.
## `Extra instructions` and `best practices`
The `improve` tool can be further customized by providing additional instructions and best practices to the AI model.
### Extra instructions
You can use the `extra_instructions` configuration option to give the AI model additional instructions for the `improve` tool.
Be specific, clear, and concise in the instructions. With extra instructions, you are the prompter.
Examples for possible instructions:
```toml
[pr_code_suggestions]
extra_instructions="""\
(1) Answer in Japanese
(2) Don't suggest to add try-except block
(3) Ignore changes in toml files
...
"""
```
Use triple quotes to write multi-line instructions. Use bullet points or numbers to make the instructions more readable.
### Best practices
> `💎 feature. Platforms supported: GitHub, GitLab, Bitbucket`
Another option to give additional guidance to the AI model is by creating a `best_practices.md` file in your repository's root directory.
This page can contain a list of best practices, coding standards, and guidelines that are specific to your repo/organization.
The AI model will use this `best_practices.md` file as a reference, and in case the PR code violates any of the guidelines, it will create additional suggestions, with a dedicated label: `Organization
best practice`.
Example for a Python `best_practices.md` content:
```markdown
## Project best practices
- Make sure that I/O operations are encapsulated in a try-except block
- Use the `logging` module for logging instead of `print` statements
- Use `is` and `is not` to compare with `None`
- Use `if __name__ == '__main__':` to run the code only when the script is executed
- Use `with` statement to open files
...
```
Tips for writing an effective `best_practices.md` file:
- Write clearly and concisely
- Include brief code examples when helpful
- Focus on project-specific guidelines, that will result in relevant suggestions you actually want to get
- Keep the file relatively short, under 800 lines, since:
- AI models may not process effectively very long documents
- Long files tend to contain generic guidelines already known to AI
To control the number of best practices suggestions generated by the `improve` tool, give the following configuration:
```toml
[best_practices]
num_best_practice_suggestions = 2
```
#### Local and global best practices
By default, Qodo Merge will look for a local `best_practices.md` in the root of the relevant local repo.
If you want to enable also a global `best_practices.md` file, set first in the global configuration file:
```toml
[best_practices]
enable_global_best_practices = true
```
Then, create a `best_practices.md` file in the root of [global](https://qodo-merge-docs.qodo.ai/usage-guide/configuration_options/#global-configuration-file) configuration repository, `pr-agent-settings`.
#### Best practices for multiple languages
For a git organization working with multiple programming languages, you can maintain a centralized global `best_practices.md` file containing language-specific guidelines.
When reviewing pull requests, Qodo Merge automatically identifies the programming language and applies the relevant best practices from this file.
To do this, structure your `best_practices.md` file using the following format:
```
# [Python]
...
# [Java]
...
# [JavaScript]
...
```
#### Dedicated label for best practices suggestions
Best practice suggestions are labeled as `Organization best practice` by default.
To customize this label, modify it in your configuration file:
```toml
[best_practices]
organization_name = "..."
```
And the label will be: `{organization_name} best practice`.
#### Example results
![best_practice](https://codium.ai/images/pr_agent/org_best_practice.png){width=512}
### Auto best practices
>`💎 feature. Platforms supported: GitHub.`
`Auto best practices` is a novel Qodo Merge capability that:
1. Identifies recurring patterns from accepted suggestions
2. **Automatically** generates [best practices page](https://github.com/qodo-ai/pr-agent/wiki/.pr_agent_auto_best_practices) based on what your team consistently values
3. Applies these learned patterns to future code reviews
This creates an automatic feedback loop where the system continuously learns from your team's choices to provide increasingly relevant suggestions.
The system maintains two analysis phases:
- Open exploration for new issues
- Targeted checking against established best practices
Note that when a [custom best practices](https://qodo-merge-docs.qodo.ai/tools/improve/#best-practices) exist, Qodo Merge will still generate an 'auto best practices' wiki file, though it won't use it in the `improve` tool.
Learn more about utilizing 'auto best practices' in our [detailed guide](https://qodo-merge-docs.qodo.ai/core-abilities/auto_best_practices/).
#### Relevant configurations
```toml
[auto_best_practices]
# Disable all auto best practices usage or generation
enable_auto_best_practices = true
# Disable usage of auto best practices file in the 'improve' tool
utilize_auto_best_practices = true
# Extra instructions to the auto best practices generation prompt
extra_instructions = ""
# Max number of patterns to be detected
max_patterns = 5
```
### Multiple best practices sources
The `improve` tool will combine best practices from all available sources - global configuration, local configuration, and auto-generated files - to provide you with comprehensive recommendations.
### Combining 'extra instructions' and 'best practices'
> `💎 feature`
The `extra instructions` configuration is more related to the `improve` tool prompt. It can be used, for example, to avoid specific suggestions ("Don't suggest to add try-except block", "Ignore changes in toml files", ...) or to emphasize specific aspects or formats ("Answer in Japanese", "Give only short suggestions", ...)
In contrast, the `best_practices.md` file is a general guideline for the way code should be written in the repo.
Using a combination of both can help the AI model to provide relevant and tailored suggestions.
## Usage Tips
### Implementing the proposed code suggestions
Each generated suggestion consists of three key elements:
1. A single-line summary of the proposed change
2. An expandable section containing a comprehensive description of the suggestion
3. A diff snippet showing the recommended code modification (before and after)
We advise users to apply critical analysis and judgment when implementing the proposed suggestions.
In addition to mistakes (which may happen, but are rare), sometimes the presented code modification may serve more as an _illustrative example_ than a directly applicable solution.
In such cases, we recommend prioritizing the suggestion's detailed description, using the diff snippet primarily as a supporting reference.
### Chat on code suggestions
> `💎 feature` Platforms supported: GitHub, GitLab
Qodo Merge implements an orchestrator agent that enables interactive code discussions, listening and responding to comments without requiring explicit tool calls.
The orchestrator intelligently analyzes your responses to determine if you want to implement a suggestion, ask a question, or request help, then delegates to the appropriate specialized tool.
#### Setup and Activation
Enable interactive code discussions by adding the following to your configuration file (default is `True`):
```toml
[pr_code_suggestions]
enable_chat_in_code_suggestions = true
```
!!! info "Activating Dynamic Responses"
To obtain dynamic responses, the following steps are required:
1. Run the `/improve` command (mostly automatic)
2. Tick the `/improve` recommendation checkboxes (_Apply this suggestion_) to have Qodo Merge generate a new inline code suggestion discussion
3. The orchestrator agent will then automatically listen and reply to comments within the discussion without requiring additional commands
#### Explore the available interaction patterns:
!!! tip "Tip: Direct the agent with keywords"
Use "implement" or "apply" for code generation. Use "explain", "why", or "how" for information and help.
=== "Asking for Details"
![Chat on code suggestions ask](https://codium.ai/images/pr_agent/improve_chat_on_code_suggestions_ask.png){width=512}
=== "Implementing Suggestions"
![Chat on code suggestions implement](https://codium.ai/images/pr_agent/improve_chat_on_code_suggestions_implement.png){width=512}
=== "Providing Additional Help"
![Chat on code suggestions help](https://codium.ai/images/pr_agent/improve_chat_on_code_suggestions_help.png){width=512}
### Dual publishing mode
Our recommended approach for presenting code suggestions is through a [table](https://qodo-merge-docs.qodo.ai/tools/improve/#overview) (`--pr_code_suggestions.commitable_code_suggestions=false`).
This method significantly reduces the PR footprint and allows for quick and easy digestion of multiple suggestions.
We also offer a complementary **dual publishing mode**. When enabled, suggestions exceeding a certain score threshold are not only displayed in the table, but also presented as committable PR comments.
This mode helps highlight suggestions deemed more critical.
To activate dual publishing mode, use the following setting:
```toml
[pr_code_suggestions]
dual_publishing_score_threshold = x
```
Where x represents the minimum score threshold (>=) for suggestions to be presented as committable PR comments in addition to the table. Default is -1 (disabled).
### Self-review
> `💎 feature` Platforms supported: GitHub, GitLab
If you set in a configuration file:
```toml
[pr_code_suggestions]
demand_code_suggestions_self_review = true
```
The `improve` tool will add a checkbox below the suggestions, prompting user to acknowledge that they have reviewed the suggestions.
You can set the content of the checkbox text via:
```toml
[pr_code_suggestions]
code_suggestions_self_review_text = "... (your text here) ..."
```
![self_review_1](https://codium.ai/images/pr_agent/self_review_1.png){width=512}
!!! tip "Tip - Reducing visual footprint after self-review 💎"
The configuration parameter `pr_code_suggestions.fold_suggestions_on_self_review` (default is True)
can be used to automatically fold the suggestions after the user clicks the self-review checkbox.
This reduces the visual footprint of the suggestions, and also indicates to the PR reviewer that the suggestions have been reviewed by the PR author, and don't require further attention.
!!! tip "Tip - Demanding self-review from the PR author 💎"
By setting:
```toml
[pr_code_suggestions]
approve_pr_on_self_review = true
```
the tool can automatically add an approval when the PR author clicks the self-review checkbox.
- If you set the number of required reviewers for a PR to 2, this effectively means that the PR author must click the self-review checkbox before the PR can be merged (in addition to a human reviewer).
![self_review_2](https://codium.ai/images/pr_agent/self_review_2.png){width=512}
- If you keep the number of required reviewers for a PR to 1 and enable this configuration, this effectively means that the PR author can approve the PR by actively clicking the self-review checkbox.
To prevent unauthorized approvals, this configuration defaults to false, and cannot be altered through online comments; enabling requires a direct update to the configuration file and a commit to the repository. This ensures that utilizing the feature demands a deliberate documented decision by the repository owner.
### Auto-approval
> `💎 feature. Platforms supported: GitHub, GitLab, Bitbucket`
Under specific conditions, Qodo Merge can auto-approve a PR when a specific comment is invoked, or when the PR meets certain criteria.
**To ensure safety, the auto-approval feature is disabled by default.**
To enable auto-approval features, you need to actively set one or both of the following options in a pre-defined _configuration file_:
```toml
[config]
enable_comment_approval = true # For approval via comments
enable_auto_approval = true # For criteria-based auto-approval
```
!!! note "Notes"
- Note that this specific flag cannot be set with a command line argument, only in the configuration file, committed to the repository.
- Enabling auto-approval must be a deliberate decision by the repository owner.
1\. **Auto-approval by commenting**
To enable auto-approval by commenting, set in the configuration file:
```toml
[config]
enable_comment_approval = true
```
After enabling, by commenting on a PR:
```
/review auto_approve
```
Qodo Merge will automatically approve the PR, and add a comment with the approval.
2\. **Auto-approval when the PR meets certain criteria**
To enable auto-approval based on specific criteria, first, you need to enable the top-level flag:
```toml
[config]
enable_auto_approval = true
```
There are two criteria that can be set for auto-approval:
- **Review effort score**
```toml
[config]
enable_auto_approval = true
auto_approve_for_low_review_effort = X # X is a number between 1 to 5
```
When the [review effort score](https://www.qodo.ai/images/pr_agent/review3.png) is lower or equal to X, the PR will be auto-approved.
___
- **No code suggestions**
```toml
[config]
enable_auto_approval = true
auto_approve_for_no_suggestions = true
```
When no [code suggestion](https://www.qodo.ai/images/pr_agent/code_suggestions_as_comment_closed.png) were found for the PR, the PR will be auto-approved.
### How many code suggestions are generated?
Qodo Merge uses a dynamic strategy to generate code suggestions based on the size of the pull request (PR). Here's how it works:
#### 1. Chunking large PRs
- Qodo Merge divides large PRs into 'chunks'.
- Each chunk contains up to `pr_code_suggestions.max_context_tokens` tokens (default: 24,000).
#### 2. Generating suggestions
- For each chunk, Qodo Merge generates up to `pr_code_suggestions.num_code_suggestions_per_chunk` suggestions (default: 4).
This approach has two main benefits:
- Scalability: The number of suggestions scales with the PR size, rather than being fixed.
- Quality: By processing smaller chunks, the AI can maintain higher quality suggestions, as larger contexts tend to decrease AI performance.
Note: Chunking is primarily relevant for large PRs. For most PRs (up to 600 lines of code), Qodo Merge will be able to process the entire code in a single call.

## Understanding AI Code Suggestions
- **AI Limitations:** AI models for code are getting better and better, but they are not flawless. Not all the suggestions will be perfect, and a user should not accept all of them automatically. Critical reading and judgment are required. Mistakes of the AI are rare but can happen, and it is usually quite easy for a human to spot them.
- **Purpose of Suggestions:**
- **Self-reflection:** The suggestions aim to enable developers to _self-reflect_ and improve their pull requests. This process can help to identify blind spots, uncover missed edge cases, and enhance code readability and coherency. Even when a specific code suggestion isn't suitable, the underlying issue it highlights often reveals something important that might deserve attention.
- **Bug detection:** The suggestions also alert on any _critical bugs_ that may have been identified during the analysis. This provides an additional safety net to catch potential issues before they make it into production. It's perfectly acceptable to implement only the suggestions you find valuable for your specific context.
- **Hierarchy:** Presenting the suggestions in a structured hierarchical table enables the user to _quickly_ understand them, and to decide which ones are relevant and which are not.
- **Customization:** To guide the model to suggestions that are more relevant to the specific needs of your project, we recommend using the [`extra_instructions`](https://qodo-merge-docs.qodo.ai/tools/improve/#extra-instructions-and-best-practices) and [`best practices`](https://qodo-merge-docs.qodo.ai/tools/improve/#best-practices) fields.
- **Model Selection:** SaaS users can also [choose](https://qodo-merge-docs.qodo.ai/usage-guide/qodo_merge_models/) between different models. For specific programming languages or use cases, some models may perform better than others.
- **Interactive usage:** The interactive [PR chat](https://qodo-merge-docs.qodo.ai/chrome-extension/) also provides an easy way to get more tailored suggestions and feedback from the AI model.

`Platforms supported: GitHub`
## Overview
The `repo_statistics` tool analyzes statistics from merged pull requests over the past 12 months prior to Qodo Merge installation.
It calculates key metrics that help teams establish a baseline of their PR workflow efficiency.
!!! note "Active repositories are needed"
The tool is designed to work with real-life repositories, as it relies on actual discussions to generate meaningful insights.
At least 30 merged PRs are required to generate meaningful statistical data.
### Metrics Analyzed
- **Time to merge:** The median and average time it takes for PRs to be merged after opening
- **Time to first comment:** The median and average time it takes to get the first comment on a PR
### Usage
The tool can be invoked manually by commenting on any PR:
```
/repo_statistics
```
In response, the bot will comment with the statistical data.
Note that the scan can take several minutes to complete, since up to 100 PRs are scanned.
!!! info "Automatic trigger"
Upon adding the Qodo Merge bot to a repository, the tool will automatically scan the last 365 days of PRs and send them to MixPanel, if enabled.
## Example usage
![repo statistics comment](https://codium.ai/images/pr_agent/repo_statistics_comment.png){width=640}
MixPanel optional presentation:
![repo statistics mixpanel](https://codium.ai/images/pr_agent/repo_statistics_mixpanel.png){width=640}
### Configuration options
- Use `/repo_statistics --repo_statistics.days_back=X` to specify the number of days back to scan for discussions. The default is 365 days.
- Use `/repo_statistics --repo_statistics.minimal_number_of_prs=X` to specify the minimum number of merged PRs needed to generate the statistics. The default is 30 PRs.

## Overview
The `review` tool scans the PR code changes, and generates a list of feedbacks about the PR, aiming to aid the reviewing process.
<br>
The tool can be triggered automatically every time a new PR is [opened](../usage-guide/automations_and_usage.md#github-app-automatic-tools-when-a-new-pr-is-opened), or can be invoked manually by commenting on any PR:
```
/review
```
Note that the main purpose of the `review` tool is to provide the **PR reviewer** with useful feedbacks and insights. The PR author, in contrast, may prefer to save time and focus on the output of the [improve](./improve.md) tool, which provides actionable code suggestions.
(Read more about the different personas in the PR process and how Qodo Merge aims to assist them in our [blog](https://www.codium.ai/blog/understanding-the-challenges-and-pain-points-of-the-pull-request-cycle/))
## Example usage
### Manual triggering
Invoke the tool manually by commenting `/review` on any PR:
![review comment](https://codium.ai/images/pr_agent/review_comment.png){width=512}
After ~30 seconds, the tool will generate a review for the PR:
![review](https://codium.ai/images/pr_agent/review3.png){width=512}
If you want to edit [configurations](#configuration-options), add the relevant ones to the command:
```
/review --pr_reviewer.some_config1=... --pr_reviewer.some_config2=...
```
### Automatic triggering
To run the `review` automatically when a PR is opened, define in a [configuration file](https://qodo-merge-docs.qodo.ai/usage-guide/configuration_options/#wiki-configuration-file):
```
[github_app]
pr_commands = [
"/review",
...
]
[pr_reviewer]
extra_instructions = "..."
...
```
- The `pr_commands` lists commands that will be executed automatically when a PR is opened.
- The `[pr_reviewer]` section contains the configurations for the `review` tool you want to edit (if any).

<td>If set to true, the tool will publish a 'Review effort [1-5]: x' label. Default is true.</td>
</tr>
</table>
## Usage Tips
!!! tip "General guidelines"
The `review` tool provides a collection of configurable feedbacks about a PR.
It is recommended to review the [Configuration options](#configuration-options) section, and choose the relevant options for your use case.
Some of the features that are disabled by default are quite useful, and should be considered for enabling. For example:
`require_score_review`, and more.
On the other hand, if you find one of the enabled features to be irrelevant for your use case, disable it. No default configuration can fit all use cases.
!!! tip "Automation"
When you first install Qodo Merge app, the [default mode](../usage-guide/automations_and_usage.md#github-app-automatic-tools-when-a-new-pr-is-opened) for the `review` tool is:
```
pr_commands = ["/review", ...]
```
Meaning the `review` tool will run automatically on every PR, without any additional configurations.
Edit this field to enable/disable the tool, or to change the configurations used.
!!! tip "Possible labels from the review tool"
The `review` tool can auto-generate two specific types of labels for a PR:
- a `possible security issue` label that detects if a possible [security issue](https://github.com/Codium-ai/pr-agent/blob/tr/user_description/pr_agent/settings/pr_reviewer_prompts.toml#L136) exists in the PR code (`enable_review_labels_security` flag)
- a `Review effort [1-5]: x` label, where x is the estimated effort to review the PR (`enable_review_labels_effort` flag)
Both modes are useful, and we recommended to enable them.
!!! tip "Extra instructions"
Extra instructions are important.
The `review` tool can be configured with extra instructions, which can be used to guide the model to a feedback tailored to the needs of your project.
Be specific, clear, and concise in the instructions. With extra instructions, you are the prompter. Specify the relevant sub-tool, and the relevant aspects of the PR that you want to emphasize.
Examples of extra instructions:
```
[pr_reviewer]
extra_instructions="""\
In the code feedback section, emphasize the following:
- Does the code logic cover relevant edge cases?
- Is the code logic clear and easy to understand?
- Is the code logic efficient?
...
"""
```
Use triple quotes to write multi-line instructions. Use bullet points to make the instructions more readable.
!!! tip "Code suggestions"
The `review` tool previously included a legacy feature for providing code suggestions (controlled by `--pr_reviewer.num_code_suggestion`). This functionality has been deprecated and replaced by the [`improve`](./improve.md) tool, which offers higher quality and more actionable code suggestions.

`Platforms supported: GitHub`
## Overview
The `scan_repo_discussions` tool analyzes code discussions (meaning review comments over code lines) from merged pull requests over the past 12 months.
It processes these discussions alongside other PR metadata to identify recurring patterns related to best practices in team feedback and code reviews, generating a comprehensive [`best_practices.md`](https://github.com/qodo-ai/pr-agent/blob/qodo-merge-best-practices_2025-04-16_1018/best_practices.md) document that distills key insights and recommendations.
This file captures repository-specific patterns derived from your team's actual workflow and discussions, rather than more generic best practices.
It will be utilized by Qodo Merge to provide tailored suggestions for improving code quality in future pull requests.
!!! note "Active repositories are needed"
The tool is designed to work with real-life repositories, as it relies on actual discussions to generate meaningful insights.
At least 50 merged PRs are required to generate the `best_practices.md` file.
!!! note "Additional customization"
Teams are encouraged to further customize and refine these insights to better align with their specific development priorities and contexts.
This can be done by editing the `best_practices.md` file directly when the PR is created, or iteratively over time to enhance the 'best practices' suggestions provided by Qodo Merge.
The tool can be invoked manually by commenting on any PR:
```
/scan_repo_discussions
```
As a response, the bot will create a new PR that contains an auto-generated `best_practices.md` file.
Note that the scan can take several minutes to complete, since up to 250 PRs are scanned.
## Example usage
![scan1](https://codium.ai/images/pr_agent/scan_repo_discussions_1.png){width=640}
The PR created by the bot:
![scan1](https://codium.ai/images/pr_agent/scan_repo_discussions_2.png){width=640}
The `best_practices.md` file in the PR:
![scan1](https://codium.ai/images/pr_agent/scan_repo_discussions_3.png){width=640}
### Configuration options
- Use `/scan_repo_discussions --scan_repo_discussions.force_scan=true` to force generating a PR with a new `best_practices.md` file, even if it already exists (by default, the bot will not generate a new file if it already exists).
- Use `/scan_repo_discussions --scan_repo_discussions.days_back=X` to specify the number of days back to scan for discussions. The default is 365 days.
- Use `/scan_repo_discussions --scan_repo_discussions.minimal_number_of_prs=X` to specify the minimum number of merged PRs needed to generate the `best_practices.md` file. The default is 50 PRs.

## Overview
The similar code tool retrieves the most similar code components from inside the organization's codebase, or from open-source code.
For example:
`Global Search` for a method called `chat_completion`:
![similar code global](https://codium.ai/images/pr_agent/similar_code_global2.png){width=768}
Qodo Merge will examine the code component and will extract the most relevant keywords to search for similar code:
- `extracted keywords`: the keywords that were extracted from the code by Qodo Merge. the link will open a search page with the extracted keywords, to allow the user to modify the search if needed.
- `search context`: the context in which the search will be performed, organization's codebase or open-source code (Global).
- `similar code`: the most similar code components found. the link will open the code component in the relevant file.
- `relevant repositories`: the open-source repositories in which that are relevant to the searched code component and it's keywords.
Search result link example:
![code search result single](https://codium.ai/images/pr_agent/code_search_result_single.png){width=768}
`Organization Search`:
![similar code org](https://codium.ai/images/pr_agent/similar_code_org.png){width=768}
## How to use
### Manually
To invoke the `similar code` tool manually, comment on the PR:
```
/find_similar_component COMPONENT_NAME
```
Where `COMPONENT_NAME` should be the name of a code component in the PR (class, method, function).
If there is a name ambiguity, there are two configurations that will help the tool to find the correct component:
- `--pr_find_similar_component.file`: in case there are several components with the same name, you can specify the relevant file.
- `--pr_find_similar_component.class_name`: in case there are several methods with the same name in the same file, you can specify the relevant class name.
example:
```
/find_similar_component COMPONENT_NAME --pr_find_similar_component.file=FILE_NAME
```
### Automatically (via Analyze table)
It can be invoked automatically from the analyze table, can be accessed by:
```
/analyze
```
Choose the components you want to find similar code for, and click on the `similar` checkbox.
![analyze similar](https://codium.ai/images/pr_agent/analyze_similar.png){width=768}
You can search for similar code either within the organization's codebase or globally, which includes open-source repositories. Each result will include the relevant code components along with their associated license details.
![similar code global](https://codium.ai/images/pr_agent/similar_code_global.png){width=768}
## Configuration options
- `search_from_org`: if set to true, the tool will search for similar code in the organization's codebase. Default is false.
- `number_of_keywords`: number of keywords to use for the search. Default is 5.
- `number_of_results`: the maximum number of results to present. Default is 5.

## Overview
By combining LLM abilities with static code analysis, the `test` tool generate tests for a selected component, based on the PR code changes.
It can be invoked manually by commenting on any PR:
```
/test component_name
```
where 'component_name' is the name of a specific component in the PR.
To get a list of the components that changed in the PR and choose the relevant component interactively, use the [`analyze`](./analyze.md) tool.
## Example usage
Invoke the tool manually by commenting `/test` on any PR:
The tool will generate tests for the selected component (if no component is stated, it will generate tests for largest component):
![test1](https://codium.ai/images/pr_agent/test1.png){width=768}
(Example taken from [here](https://github.com/Codium-ai/pr-agent/pull/598#issuecomment-1913679429)):
!!! note "Notes"
- The following languages are currently supported: Python, Java, C++, JavaScript, TypeScript, C#.
- This tool can also be triggered interactively by using the [`analyze`](./analyze.md) tool.
## Configuration options
- `num_tests`: number of tests to generate. Default is 3.
- `testing_framework`: the testing framework to use. If not set, for Python it will use `pytest`, for Java it will use `JUnit`, for C++ it will use `Catch2`, and for JavaScript and TypeScript it will use `jest`.
- `avoid_mocks`: if set to true, the tool will try to avoid using mocks in the generated tests. Note that even if this option is set to true, the tool might still use mocks if it cannot generate a test without them. Default is true.
- `extra_instructions`: Optional extra instructions to the tool. For example: "use the following mock injection scheme: ...".
- `file`: in case there are several components with the same name, you can specify the relevant file.
- `class_name`: in case there are several methods with the same name in the same file, you can specify the relevant class name.
- `enable_help_text`: if set to true, the tool will add a help text to the PR comment. Default is true.

## Configuration options
Under the section `pr_update_changelog`, the [configuration file](https://github.com/Codium-ai/pr-agent/blob/main/pr_agent/settings/configuration.toml#L50) contains options to customize the 'update changelog' tool:
- `push_changelog_changes`: whether to push the changes to CHANGELOG.md, or just publish them as a comment. Default is false (publish as comment).
- `extra_instructions`: Optional extra instructions to the tool. For example: "Use the following structure: ..."
- `add_pr_link`: whether the model should try to add a link to the PR in the changelog. Default is true.
- `skip_ci_on_push`: whether the commit message (when `push_changelog_changes` is true) will include the term "[skip ci]", preventing CI tests to be triggered on the changelog commit. Default is true.

## Recommend Python Best Practices
This document outlines a series of recommended best practices for Python development. These guidelines aim to improve code quality, maintainability, and readability.
### Imports
Use `import` statements for packages and modules only, not for individual types, classes, or functions.
#### Definition
Reusability mechanism for sharing code from one module to another.
#### Decision
- Use `import x` for importing packages and modules.
- Use `from x import y` where `x` is the package prefix and `y` is the module name with no prefix.
- Use `from x import y as z` in any of the following circumstances:
- Two modules named `y` are to be imported.
- `y` conflicts with a top-level name defined in the current module.
- `y` conflicts with a common parameter name that is part of the public API (e.g., `features`).
- `y` is an inconveniently long name, or too generic in the context of your code
- Use `import y as z` only when `z` is a standard abbreviation (e.g., `import numpy as np`).
For example the module `sound.effects.echo` may be imported as follows:
```
from sound.effects import echo
...
echo.EchoFilter(input, output, delay=0.7, atten=4)
```
Do not use relative names in imports. Even if the module is in the same package, use the full package name. This helps prevent unintentionally importing a package twice.
##### Exemptions
Exemptions from this rule:
- Symbols from the following modules are used to support static analysis and type checking:
- [`typing` module](https://google.github.io/styleguide/pyguide.html#typing-imports)
- [`collections.abc` module](https://google.github.io/styleguide/pyguide.html#typing-imports)
- [`typing_extensions` module](https://github.com/python/typing_extensions/blob/main/README.md)
- Redirects from the [six.moves module](https://six.readthedocs.io/#module-six.moves).
### Packages
Import each module using the full pathname location of the module.
#### Decision
All new code should import each module by its full package name.
Imports should be as follows:
```
Yes:
# Reference absl.flags in code with the complete name (verbose).
import absl.flags
from doctor.who import jodie
_FOO = absl.flags.DEFINE_string(...)
```
```
Yes:
# Reference flags in code with just the module name (common).
from absl import flags
from doctor.who import jodie
_FOO = flags.DEFINE_string(...)
```
_(assume this file lives in `doctor/who/` where `jodie.py` also exists)_
```
No:
# Unclear what module the author wanted and what will be imported. The actual
# import behavior depends on external factors controlling sys.path.
# Which possible jodie module did the author intend to import?
import jodie
```
The directory the main binary is located in should not be assumed to be in `sys.path` despite that happening in some environments. This being the case, code should assume that `import jodie` refers to a third-party or top-level package named `jodie`, not a local `jodie.py`.
### Default Iterators and Operators
Use default iterators and operators for types that support them, like lists, dictionaries, and files.
#### Definition
Container types, like dictionaries and lists, define default iterators and membership test operators (“in” and “not in”).
#### Decision
Use default iterators and operators for types that support them, like lists, dictionaries, and files. The built-in types define iterator methods, too. Prefer these methods to methods that return lists, except that you should not mutate a container while iterating over it.
```
Yes: for key in adict: ...
if obj in alist: ...
for line in afile: ...
for k, v in adict.items(): ...
```
```
No: for key in adict.keys(): ...
for line in afile.readlines(): ...
```
### Lambda Functions
Okay for one-liners. Prefer generator expressions over `map()` or `filter()` with a `lambda`.
#### Decision
Lambdas are allowed. If the code inside the lambda function spans multiple lines or is longer than 60-80 chars, it might be better to define it as a regular [nested function](https://google.github.io/styleguide/pyguide.html#lexical-scoping).
For common operations like multiplication, use the functions from the `operator` module instead of lambda functions. For example, prefer `operator.mul` to `lambda x, y: x * y`.
### Default Argument Values
Okay in most cases.
#### Definition
You can specify values for variables at the end of a functions parameter list, e.g., `def foo(a, b=0):`. If `foo` is called with only one argument, `b` is set to 0. If it is called with two arguments, `b` has the value of the second argument.
#### Decision
Okay to use with the following caveat:
Do not use mutable objects as default values in the function or method definition.
```
Yes: def foo(a, b=None):
if b is None:
b = []
Yes: def foo(a, b: Sequence | None = None):
if b is None:
b = []
Yes: def foo(a, b: Sequence = ()): # Empty tuple OK since tuples are immutable.
...
```
```
from absl import flags
_FOO = flags.DEFINE_string(...)
No: def foo(a, b=[]):
...
No: def foo(a, b=time.time()): # Is `b` supposed to represent when this module was loaded?
...
No: def foo(a, b=_FOO.value): # sys.argv has not yet been parsed...
...
No: def foo(a, b: Mapping = {}): # Could still get passed to unchecked code.
...
```
### True/False Evaluations
Use the “implicit” false if possible, e.g., `if foo:` rather than `if foo != []:`
### Lexical Scoping
Okay to use.
An example of the use of this feature is:
```
def get_adder(summand1: float) -> Callable[[float], float]:
"""Returns a function that adds numbers to a given number."""
def adder(summand2: float) -> float:
return summand1 + summand2
return adder
```
#### Decision
Okay to use.
### Threading
Do not rely on the atomicity of built-in types.
While Pythons built-in data types such as dictionaries appear to have atomic operations, there are corner cases where they arent atomic (e.g. if `__hash__` or `__eq__` are implemented as Python methods) and their atomicity should not be relied upon. Neither should you rely on atomic variable assignment (since this in turn depends on dictionaries).
Use the `queue` modules `Queue` data type as the preferred way to communicate data between threads. Otherwise, use the `threading` module and its locking primitives. Prefer condition variables and `threading.Condition` instead of using lower-level locks.

## Show possible configurations
The possible configurations of Qodo Merge are stored in [here](https://github.com/Codium-ai/pr-agent/blob/main/pr_agent/settings/configuration.toml){:target="_blank"}.
In the [tools](https://qodo-merge-docs.qodo.ai/tools/) page you can find explanations on how to use these configurations for each tool.
To print all the available configurations as a comment on your PR, you can use the following command:
```
/config
```
![possible_config1](https://codium.ai/images/pr_agent/possible_config1.png){width=512}
To view the **actual** configurations used for a specific tool, after all the user settings are applied, you can add for each tool a `--config.output_relevant_configurations=true` suffix.
For example:
```
/improve --config.output_relevant_configurations=true
```
Will output an additional field showing the actual configurations used for the `improve` tool.
![possible_config2](https://codium.ai/images/pr_agent/possible_config2.png){width=512}
## Ignoring files from analysis
In some cases, you may want to exclude specific files or directories from the analysis performed by Qodo Merge. This can be useful, for example, when you have files that are generated automatically or files that shouldn't be reviewed, like vendor code.
You can ignore files or folders using the following methods:
- `IGNORE.GLOB`
- `IGNORE.REGEX`
which you can edit to ignore files or folders based on glob or regex patterns.
### Example usage
Let's look at an example where we want to ignore all files with `.py` extension from the analysis.
To ignore Python files in a PR with online usage, comment on a PR:
`/review --ignore.glob="['*.py']"`
To ignore Python files in all PRs using `glob` pattern, set in a configuration file:
```
[ignore]
glob = ['*.py']
```
And to ignore Python files in all PRs using `regex` pattern, set in a configuration file:
```
[regex]
regex = ['.*\.py$']
```
## Extra instructions
All Qodo Merge tools have a parameter called `extra_instructions`, that enables to add free-text extra instructions. Example usage:
```
/update_changelog --pr_update_changelog.extra_instructions="Make sure to update also the version ..."
```
## Language Settings
The default response language for Qodo Merge is **U.S. English**. However, some development teams may prefer to display information in a different language. For example, your team's workflow might improve if PR descriptions and code suggestions are set to your country's native language.
To configure this, set the `response_language` parameter in the configuration file. This will prompt the model to respond in the specified language. Use a **standard locale code** based on [ISO 3166](https://en.wikipedia.org/wiki/ISO_3166) (country codes) and [ISO 639](https://en.wikipedia.org/wiki/ISO_639) (language codes) to define a language-country pair. See this [comprehensive list of locale codes](https://simplelocalize.io/data/locales/).
Example:
```toml
[config]
response_language = "it-IT"
```
This will set the response language globally for all the commands to Italian.
> **Important:** Note that only dynamic text generated by the AI model is translated to the configured language. Static text such as labels and table headers that are not part of the AI models response will remain in US English. In addition, the model you are using must have good support for the specified language.
[//]: # (## Working with large PRs)

[//]: # (which divides the PR into chunks, and processes each chunk separately. With this mode, regardless of the model, no compression will be done &#40;but for large PRs, multiple model calls may occur&#41;)
## Patch Extra Lines
By default, around any change in your PR, git patch provides three lines of context above and below the change.
```
@@ -12,5 +12,5 @@ def func1():
code line that already existed in the file...
code line that already existed in the file...
code line that already existed in the file....
-code line that was removed in the PR
+new code line added in the PR
code line that already existed in the file...
code line that already existed in the file...
code line that already existed in the file...
```
Qodo Merge will try to increase the number of lines of context, via the parameter:
```
[config]
patch_extra_lines_before=3
patch_extra_lines_after=1
```
Increasing this number provides more context to the model, but will also increase the token budget, and may overwhelm the model with too much information, unrelated to the actual PR code changes.
If the PR is too large (see [PR Compression strategy](https://github.com/Codium-ai/pr-agent/blob/main/PR_COMPRESSION.md)), Qodo Merge may automatically set this number to 0, and will use the original git patch.
## Log Level
Qodo Merge allows you to control the verbosity of logging by using the `log_level` configuration parameter. This is particularly useful for troubleshooting and debugging issues with your PR workflows.
```
[config]
log_level = "DEBUG" # Options: "DEBUG", "INFO", "WARNING", "ERROR", "CRITICAL"
```
The default log level is "DEBUG", which provides detailed output of all operations. If you prefer less verbose logs, you can set higher log levels like "INFO" or "WARNING".
## Integrating with Logging Observability Platforms
Various logging observability tools can be used out-of-the box when using the default LiteLLM AI Handler. Simply configure the LiteLLM callback settings in `configuration.toml` and set environment variables according to the LiteLLM [documentation](https://docs.litellm.ai/docs/).
For example, to use [LangSmith](https://www.langchain.com/langsmith) you can add the following to your `configuration.toml` file:
```
[litellm]
enable_callbacks = true
success_callback = ["langsmith"]
failure_callback = ["langsmith"]
service_callback = []
```
Then set the following environment variables:
```
LANGSMITH_API_KEY=<api_key>
LANGSMITH_PROJECT=<project>
LANGSMITH_BASE_URL=<url>
```
## Ignoring automatic commands in PRs
Qodo Merge allows you to automatically ignore certain PRs based on various criteria:
- PRs with specific titles (using regex matching)
- PRs between specific branches (using regex matching)
- PRs from specific repositories (using regex matching)
- PRs not from specific folders
- PRs containing specific labels
- PRs opened by specific users
### Ignoring PRs with specific titles
To ignore PRs with a specific title such as "[Bump]: ...", you can add the following to your `configuration.toml` file:
```toml
[config]
ignore_pr_title = ["\\[Bump\\]"]
```
Where the `ignore_pr_title` is a list of regex patterns to match the PR title you want to ignore. Default is `ignore_pr_title = ["^\\[Auto\\]", "^Auto"]`.
### Ignoring PRs between specific branches
To ignore PRs from specific source or target branches, you can add the following to your `configuration.toml` file:
```toml
[config]
ignore_pr_source_branches = ['develop', 'main', 'master', 'stage']
ignore_pr_target_branches = ["qa"]
```
Where the `ignore_pr_source_branches` and `ignore_pr_target_branches` are lists of regex patterns to match the source and target branches you want to ignore.
They are not mutually exclusive, you can use them together or separately.
### Ignoring PRs from specific repositories
To ignore PRs from specific repositories, you can add the following to your `configuration.toml` file:
```toml
[config]
ignore_repositories = ["my-org/my-repo1", "my-org/my-repo2"]
```
Where the `ignore_repositories` is a list of regex patterns to match the repositories you want to ignore. This is useful when you have multiple repositories and want to exclude certain ones from analysis.
### Ignoring PRs not from specific folders
To allow only specific folders (often needed in large monorepos), set:
```
[config]
allow_only_specific_folders=['folder1','folder2']
```
For the configuration above, automatic feedback will only be triggered when the PR changes include files where 'folder1' or 'folder2' is in the file path
### Ignoring PRs containing specific labels
To ignore PRs containing specific labels, you can add the following to your `configuration.toml` file:
```
[config]
ignore_pr_labels = ["do-not-merge"]
```
Where the `ignore_pr_labels` is a list of labels that when present in the PR, the PR will be ignored.
### Ignoring PRs from specific users
Qodo Merge tries to automatically identify and ignore pull requests created by bots using:
- GitHub's native bot detection system
- Name-based pattern matching
While this detection is robust, it may not catch all cases, particularly when:
- Bots are registered as regular user accounts
- Bot names don't match common patterns
To supplement the automatic bot detection, you can manually specify users to ignore. Add the following to your `configuration.toml` file to ignore PRs from specific users:
```
[config]
ignore_pr_authors = ["my-special-bot-user", ...]
```
Where the `ignore_pr_authors` is a list of usernames that you want to ignore.
!!! note
There is one specific case where bots will receive an automatic response - when they generated a PR with a _failed test_. In that case, the [`ci_feedback`](https://qodo-merge-docs.qodo.ai/tools/ci_feedback/) tool will be invoked.

## Local repo (CLI)
When running from your locally cloned Qodo Merge repo (CLI), your local configuration file will be used.
Examples of invoking the different tools via the CLI:
- **Review**: `python -m pr_agent.cli --pr_url=<pr_url> review`
- **Describe**: `python -m pr_agent.cli --pr_url=<pr_url> describe`
- **Improve**: `python -m pr_agent.cli --pr_url=<pr_url> improve`
- **Ask**: `python -m pr_agent.cli --pr_url=<pr_url> ask "Write me a poem about this PR"`
- **Update Changelog**: `python -m pr_agent.cli --pr_url=<pr_url> update_changelog`
`<pr_url>` is the url of the relevant PR (for example: [#50](https://github.com/Codium-ai/pr-agent/pull/50)).
**Notes:**
1. in addition to editing your local configuration file, you can also change any configuration value by adding it to the command line:
```
python -m pr_agent.cli --pr_url=<pr_url> /review --pr_reviewer.extra_instructions="focus on the file: ..."
```
2. You can print results locally, without publishing them, by setting in `configuration.toml`:
```
[config]
publish_output=false
verbosity_level=2
```
This is useful for debugging or experimenting with different tools.
3. **git provider**: The [git_provider](https://github.com/Codium-ai/pr-agent/blob/main/pr_agent/settings/configuration.toml#L5) field in a configuration file determines the GIT provider that will be used by Qodo Merge. Currently, the following providers are supported:
`github` **(default)**, `gitlab`, `bitbucket`, `azure`, `codecommit`, `local`, and `gerrit`.
### CLI Health Check
To verify that Qodo Merge has been configured correctly, you can run this health check command from the repository root:
```bash
python -m tests.health_test.main
```
If the health check passes, you will see the following output:
```
========
Health test passed successfully
========
```
At the end of the run.
Before running the health check, ensure you have:
- Configured your [LLM provider](https://qodo-merge-docs.qodo.ai/usage-guide/changing_a_model/)
- Added a valid GitHub token to your configuration file
## Online usage
Online usage means invoking Qodo Merge tools by [comments](https://github.com/Codium-ai/pr-agent/pull/229#issuecomment-1695021901) on a PR.
Commands for invoking the different tools via comments:
- **Review**: `/review`
- **Describe**: `/describe`
- **Improve**: `/improve` (or `/improve_code` for bitbucket, since `/improve` is sometimes reserved)
- **Ask**: `/ask "..."`
- **Update Changelog**: `/update_changelog`
To edit a specific configuration value, just add `--config_path=<value>` to any command.
For example, if you want to edit the `review` tool configurations, you can run:
```
/review --pr_reviewer.extra_instructions="..." --pr_reviewer.require_score_review=false
```
Any configuration value in [configuration file](https://github.com/Codium-ai/pr-agent/blob/main/pr_agent/settings/configuration.toml) file can be similarly edited. Comment `/config` to see the list of available configurations.
## Qodo Merge Automatic Feedback
### Disabling all automatic feedback
To easily disable all automatic feedback from Qodo Merge (GitHub App, GitLab Webhook, BitBucket App, Azure DevOps Webhook), set in a configuration file:
```toml
[config]
disable_auto_feedback = true
```
When this parameter is set to `true`, Qodo Merge will not run any automatic tools (like `describe`, `review`, `improve`) when a new PR is opened, or when new code is pushed to an open PR.
### GitHub App
!!! note "Configurations for Qodo Merge"
Qodo Merge for GitHub is an App, hosted by Qodo. So all the instructions below are relevant also for Qodo Merge users.
Same goes for [GitLab webhook](#gitlab-webhook) and [BitBucket App](#bitbucket-app) sections.
#### GitHub app automatic tools when a new PR is opened
The [github_app](https://github.com/Codium-ai/pr-agent/blob/main/pr_agent/settings/configuration.toml#L220) section defines GitHub app specific configurations.
The configuration parameter `pr_commands` defines the list of tools that will be **run automatically** when a new PR is opened:
```toml
[github_app]
pr_commands = [
"/describe",
"/review",
"/improve",
]
```
This means that when a new PR is opened/reopened or marked as ready for review, Qodo Merge will run the `describe`, `review` and `improve` tools.
**Draft PRs:**
By default, draft PRs are not considered for automatic tools, but you can change this by setting the `feedback_on_draft_pr` parameter to `true` in the configuration file.
```toml
[github_app]
feedback_on_draft_pr = true
```
**Changing default tool parameters:**
You can override the default tool parameters by using one the three options for a [configuration file](https://qodo-merge-docs.qodo.ai/usage-guide/configuration_options/): **wiki**, **local**, or **global**.
For example, if your configuration file contains:
```toml
[pr_description]
generate_ai_title = true
```
Every time you run the `describe` tool (including automatic runs) the PR title will be generated by the AI.
**Parameters for automated runs:**
You can customize configurations specifically for automated runs by using the `--config_path=<value>` parameter.
For instance, to modify the `review` tool settings only for newly opened PRs, use:
```toml
[github_app]
pr_commands = [
"/describe",
"/review --pr_reviewer.extra_instructions='focus on the file: ...'",
"/improve",
]
```
#### GitHub app automatic tools for push actions (commits to an open PR)
In addition to running automatic tools when a PR is opened, the GitHub app can also respond to new code that is pushed to an open PR.
The configuration toggle `handle_push_trigger` can be used to enable this feature.
The configuration parameter `push_commands` defines the list of tools that will be **run automatically** when new code is pushed to the PR.
```toml
[github_app]
handle_push_trigger = true
push_commands = [
"/describe",
"/review",
]
```
This means that when new code is pushed to the PR, the Qodo Merge will run the `describe` and `review` tools, with the specified parameters.
### GitHub Action
`GitHub Action` is a different way to trigger Qodo Merge tools, and uses a different configuration mechanism than `GitHub App`.<br>
You can configure settings for `GitHub Action` by adding environment variables under the env section in `.github/workflows/pr_agent.yml` file.
Specifically, start by setting the following environment variables:
```yaml
env:
OPENAI_KEY: ${{ secrets.OPENAI_KEY }} # Make sure to add your OpenAI key to your repo secrets
GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }} # Make sure to add your GitHub token to your repo secrets
github_action_config.auto_review: "true" # enable\disable auto review
github_action_config.auto_describe: "true" # enable\disable auto describe
github_action_config.auto_improve: "true" # enable\disable auto improve
github_action_config.pr_actions: '["opened", "reopened", "ready_for_review", "review_requested"]'
```
`github_action_config.auto_review`, `github_action_config.auto_describe` and `github_action_config.auto_improve` are used to enable/disable automatic tools that run when a new PR is opened.
If not set, the default configuration is for all three tools to run automatically when a new PR is opened.
`github_action_config.pr_actions` is used to configure which `pull_requests` events will trigger the enabled auto flags
If not set, the default configuration is `["opened", "reopened", "ready_for_review", "review_requested"]`
`github_action_config.enable_output` are used to enable/disable github actions [output parameter](https://docs.github.com/en/actions/creating-actions/metadata-syntax-for-github-actions#outputs-for-docker-container-and-javascript-actions) (default is `true`).
Review result is output as JSON to `steps.{step-id}.outputs.review` property.
The JSON structure is equivalent to the yaml data structure defined in [pr_reviewer_prompts.toml](https://github.com/qodo-ai/pr-agent/blob/main/pr_agent/settings/pr_reviewer_prompts.toml).
Note that you can give additional config parameters by adding environment variables to `.github/workflows/pr_agent.yml`, or by using a `.pr_agent.toml` [configuration file](https://qodo-merge-docs.qodo.ai/usage-guide/configuration_options/#global-configuration-file) in the root of your repo
For example, you can set an environment variable: `pr_description.publish_labels=false`, or add a `.pr_agent.toml` file with the following content:
```toml
[pr_description]
publish_labels = false
```
to prevent Qodo Merge from publishing labels when running the `describe` tool.
### GitLab Webhook
After setting up a GitLab webhook, to control which commands will run automatically when a new MR is opened, you can set the `pr_commands` parameter in the configuration file, similar to the GitHub App:
```toml
[gitlab]
pr_commands = [
"/describe",
"/review",
"/improve",
]
```
the GitLab webhook can also respond to new code that is pushed to an open MR.
The configuration toggle `handle_push_trigger` can be used to enable this feature.
The configuration parameter `push_commands` defines the list of tools that will be **run automatically** when new code is pushed to the MR.
```toml
[gitlab]
handle_push_trigger = true
push_commands = [
"/describe",
"/review",
]
```
Note that to use the 'handle_push_trigger' feature, you need to give the gitlab webhook also the "Push events" scope.
### BitBucket App
Similar to GitHub app, when running Qodo Merge from BitBucket App, the default [configuration file](https://github.com/Codium-ai/pr-agent/blob/main/pr_agent/settings/configuration.toml) will be initially loaded.
By uploading a local `.pr_agent.toml` file to the root of the repo's default branch, you can edit and customize any configuration parameter. Note that you need to upload `.pr_agent.toml` prior to creating a PR, in order for the configuration to take effect.
For example, if your local `.pr_agent.toml` file contains:
```toml
[pr_reviewer]
extra_instructions = "Answer in japanese"
```
Each time you invoke a `/review` tool, it will use the extra instructions you set in the local configuration file.
Note that among other limitations, BitBucket provides relatively low rate-limits for applications (up to 1000 requests per hour), and does not provide an API to track the actual rate-limit usage.
If you experience a lack of responses from Qodo Merge, you might want to set: `bitbucket_app.avoid_full_files=true` in your configuration file.
This will prevent Qodo Merge from acquiring the full file content, and will only use the diff content. This will reduce the number of requests made to BitBucket, at the cost of small decrease in accuracy, as dynamic context will not be applicable.
#### BitBucket Self-Hosted App automatic tools
To control which commands will run automatically when a new PR is opened, you can set the `pr_commands` parameter in the configuration file:
Specifically, set the following values:
```toml
[bitbucket_app]
pr_commands = [
"/review",
"/improve --pr_code_suggestions.commitable_code_suggestions=true --pr_code_suggestions.suggestions_score_threshold=7",
]
```
Note that we set specifically for bitbucket, we recommend using: `--pr_code_suggestions.suggestions_score_threshold=7` and that is the default value we set for bitbucket.
Since this platform only supports inline code suggestions, we want to limit the number of suggestions, and only present a limited number.
To enable BitBucket app to respond to each **push** to the PR, set (for example):
```toml
[bitbucket_app]
handle_push_trigger = true
push_commands = [
"/describe",
"/review",
]
```
### Azure DevOps provider
To use Azure DevOps provider use the following settings in configuration.toml:
```toml
[config]
git_provider="azure"
```
Azure DevOps provider supports [PAT token](https://learn.microsoft.com/en-us/azure/devops/organizations/accounts/use-personal-access-tokens-to-authenticate?view=azure-devops&tabs=Windows) or [DefaultAzureCredential](https://learn.microsoft.com/en-us/azure/developer/python/sdk/authentication-overview#authentication-in-server-environments) authentication.
PAT is faster to create, but has build in expiration date, and will use the user identity for API calls.
Using DefaultAzureCredential you can use managed identity or Service principle, which are more secure and will create separate ADO user identity (via AAD) to the agent.
If PAT was chosen, you can assign the value in .secrets.toml.
If DefaultAzureCredential was chosen, you can assigned the additional env vars like AZURE_CLIENT_SECRET directly,
or use managed identity/az cli (for local development) without any additional configuration.
in any case, 'org' value must be assigned in .secrets.toml:
```
[azure_devops]
org = "https://dev.azure.com/YOUR_ORGANIZATION/"
# pat = "YOUR_PAT_TOKEN" needed only if using PAT for authentication
```
#### Azure DevOps Webhook
To control which commands will run automatically when a new PR is opened, you can set the `pr_commands` parameter in the configuration file, similar to the GitHub App:
```toml
[azure_devops_server]
pr_commands = [
"/describe",
"/review",
"/improve",
]
```

## Changing a model in PR-Agent
See [here](https://github.com/Codium-ai/pr-agent/blob/main/pr_agent/algo/__init__.py) for a list of available models.
To use a different model than the default (o4-mini), you need to edit in the [configuration file](https://github.com/Codium-ai/pr-agent/blob/main/pr_agent/settings/configuration.toml#L2) the fields:
```toml
[config]
model = "..."
fallback_models = ["..."]
```
For models and environments not from OpenAI, you might need to provide additional keys and other parameters.
You can give parameters via a configuration file, or from environment variables.
!!! note "Model-specific environment variables"
See [litellm documentation](https://litellm.vercel.app/docs/proxy/quick_start#supported-llms) for the environment variables needed per model, as they may vary and change over time. Our documentation per-model may not always be up-to-date with the latest changes.
Failing to set the needed keys of a specific model will usually result in litellm not identifying the model type, and failing to utilize it.
### OpenAI like API
To use an OpenAI like API, set the following in your `.secrets.toml` file:
```toml
[openai]
api_base = "https://api.openai.com/v1"
api_key = "sk-..."
```
or use the environment variables (make sure to use double underscores `__`):
```bash
OPENAI__API_BASE=https://api.openai.com/v1
OPENAI__KEY=sk-...
```
### Azure
To use Azure, set in your `.secrets.toml` (working from CLI), or in the GitHub `Settings > Secrets and variables` (working from GitHub App or GitHub Action):
```toml
[openai]
key = "" # your azure api key
api_type = "azure"
api_version = '2023-05-15' # Check Azure documentation for the current API version
api_base = "" # The base URL for your Azure OpenAI resource. e.g. "https://<your resource name>.openai.azure.com"
deployment_id = "" # The deployment name you chose when you deployed the engine
```
and set in your configuration file:
```toml
[config]
model="" # the OpenAI model you've deployed on Azure (e.g. gpt-4o)
fallback_models=["..."]
```
To use Azure AD (Entra id) based authentication set in your `.secrets.toml` (working from CLI), or in the GitHub `Settings > Secrets and variables` (working from GitHub App or GitHub Action):
```toml
[azure_ad]
client_id = "" # Your Azure AD application client ID
client_secret = "" # Your Azure AD application client secret
tenant_id = "" # Your Azure AD tenant ID
api_base = "" # Your Azure OpenAI service base URL (e.g., https://openai.xyz.com/)
```
Passing custom headers to the underlying LLM Model API can be done by setting extra_headers parameter to litellm.
```toml
[litellm]
extra_headers='{"projectId": "<authorized projectId >", ...}') #The value of this setting should be a JSON string representing the desired headers, a ValueError is thrown otherwise.
```
This enables users to pass authorization tokens or API keys, when routing requests through an API management gateway.
### Ollama
You can run models locally through either [VLLM](https://docs.litellm.ai/docs/providers/vllm) or [Ollama](https://docs.litellm.ai/docs/providers/ollama)
E.g. to use a new model locally via Ollama, set in `.secrets.toml` or in a configuration file:
```toml
[config]
model = "ollama/qwen2.5-coder:32b"
fallback_models=["ollama/qwen2.5-coder:32b"]
custom_model_max_tokens=128000 # set the maximal input tokens for the model
duplicate_examples=true # will duplicate the examples in the prompt, to help the model to generate structured output
[ollama]
api_base = "http://localhost:11434" # or whatever port you're running Ollama on
```
By default, Ollama uses a context window size of 2048 tokens. In most cases this is not enough to cover pr-agent promt and pull-request diff. Context window size can be overridden with the `OLLAMA_CONTEXT_LENGTH` environment variable. For example, to set the default context length to 8K, use: `OLLAMA_CONTEXT_LENGTH=8192 ollama serve`. More information you can find on the [official ollama faq](https://github.com/ollama/ollama/blob/main/docs/faq.md#how-can-i-specify-the-context-window-size).
Please note that the `custom_model_max_tokens` setting should be configured in accordance with the `OLLAMA_CONTEXT_LENGTH`. Failure to do so may result in unexpected model output.
!!! note "Local models vs commercial models"
Qodo Merge is compatible with almost any AI model, but analyzing complex code repositories and pull requests requires a model specifically optimized for code analysis.
Commercial models such as GPT-4, Claude Sonnet, and Gemini have demonstrated robust capabilities in generating structured output for code analysis tasks with large input. In contrast, most open-source models currently available (as of January 2025) face challenges with these complex tasks.
Based on our testing, local open-source models are suitable for experimentation and learning purposes (mainly for the `ask` command), but they are not suitable for production-level code analysis tasks.
Hence, for production workflows and real-world usage, we recommend using commercial models.
### Hugging Face
To use a new model with Hugging Face Inference Endpoints, for example, set:
```toml
[config] # in configuration.toml
model = "huggingface/meta-llama/Llama-2-7b-chat-hf"
fallback_models=["huggingface/meta-llama/Llama-2-7b-chat-hf"]
custom_model_max_tokens=... # set the maximal input tokens for the model
[huggingface] # in .secrets.toml
key = ... # your Hugging Face api key
api_base = ... # the base url for your Hugging Face inference endpoint
```
(you can obtain a Llama2 key from [here](https://replicate.com/replicate/llama-2-70b-chat/api))
### Replicate
To use Llama2 model with Replicate, for example, set:
```toml
[config] # in configuration.toml
model = "replicate/llama-2-70b-chat:2c1608e18606fad2812020dc541930f2d0495ce32eee50074220b87300bc16e1"
fallback_models=["replicate/llama-2-70b-chat:2c1608e18606fad2812020dc541930f2d0495ce32eee50074220b87300bc16e1"]
[replicate] # in .secrets.toml
key = ...
```
(you can obtain a Llama2 key from [here](https://replicate.com/replicate/llama-2-70b-chat/api))
Also, review the [AiHandler](https://github.com/Codium-ai/pr-agent/blob/main/pr_agent/algo/ai_handler.py) file for instructions on how to set keys for other models.
### Groq
To use Llama3 model with Groq, for example, set:
```toml
[config] # in configuration.toml
model = "llama3-70b-8192"
fallback_models = ["groq/llama3-70b-8192"]
[groq] # in .secrets.toml
key = ... # your Groq api key
```
(you can obtain a Groq key from [here](https://console.groq.com/keys))
### xAI
To use xAI's models with PR-Agent, set:
```toml
[config] # in configuration.toml
model = "xai/grok-2-latest"
fallback_models = ["xai/grok-2-latest"] # or any other model as fallback
[xai] # in .secrets.toml
key = "..." # your xAI API key
```
You can obtain an xAI API key from [xAI's console](https://console.x.ai/) by creating an account and navigating to the developer settings page.
### Vertex AI
To use Google's Vertex AI platform and its associated models (chat-bison/codechat-bison) set:
```toml
[config] # in configuration.toml
model = "vertex_ai/codechat-bison"
fallback_models="vertex_ai/codechat-bison"
[vertexai] # in .secrets.toml
vertex_project = "my-google-cloud-project"
vertex_location = ""
```
Your [application default credentials](https://cloud.google.com/docs/authentication/application-default-credentials) will be used for authentication so there is no need to set explicit credentials in most environments.
If you do want to set explicit credentials, then you can use the `GOOGLE_APPLICATION_CREDENTIALS` environment variable set to a path to a json credentials file.
### Google AI Studio
To use [Google AI Studio](https://aistudio.google.com/) models, set the relevant models in the configuration section of the configuration file:
```toml
[config] # in configuration.toml
model="gemini/gemini-1.5-flash"
fallback_models=["gemini/gemini-1.5-flash"]
[google_ai_studio] # in .secrets.toml
gemini_api_key = "..."
```
If you don't want to set the API key in the .secrets.toml file, you can set the `GOOGLE_AI_STUDIO.GEMINI_API_KEY` environment variable.
### Anthropic
To use Anthropic models, set the relevant models in the configuration section of the configuration file:
```toml
[config]
model="anthropic/claude-3-opus-20240229"
fallback_models=["anthropic/claude-3-opus-20240229"]
```
And also set the api key in the .secrets.toml file:
```toml
[anthropic]
KEY = "..."
```
See [litellm](https://docs.litellm.ai/docs/providers/anthropic#usage) documentation for more information about the environment variables required for Anthropic.
### Amazon Bedrock
To use Amazon Bedrock and its foundational models, add the below configuration:
```toml
[config] # in configuration.toml
model="bedrock/anthropic.claude-3-5-sonnet-20240620-v1:0"
fallback_models=["bedrock/anthropic.claude-3-5-sonnet-20240620-v1:0"]
[aws]
AWS_ACCESS_KEY_ID="..."
AWS_SECRET_ACCESS_KEY="..."
AWS_REGION_NAME="..."
```
See [litellm](https://docs.litellm.ai/docs/providers/bedrock#usage) documentation for more information about the environment variables required for Amazon Bedrock.
### DeepSeek
To use deepseek-chat model with DeepSeek, for example, set:
```toml
[config] # in configuration.toml
model = "deepseek/deepseek-chat"
fallback_models=["deepseek/deepseek-chat"]
```
and fill up your key
```toml
[deepseek] # in .secrets.toml
key = ...
```
(you can obtain a deepseek-chat key from [here](https://platform.deepseek.com))
### DeepInfra
To use DeepSeek model with DeepInfra, for example, set:
```toml
[config] # in configuration.toml
model = "deepinfra/deepseek-ai/DeepSeek-R1-Distill-Llama-70B"
fallback_models = ["deepinfra/deepseek-ai/DeepSeek-R1-Distill-Qwen-32B"]
[deepinfra] # in .secrets.toml
key = ... # your DeepInfra api key
```
(you can obtain a DeepInfra key from [here](https://deepinfra.com/dash/api_keys))
### Mistral
To use models like Mistral or Codestral with Mistral, for example, set:
```toml
[config] # in configuration.toml
model = "mistral/mistral-small-latest"
fallback_models = ["mistral/mistral-medium-latest"]
[mistral] # in .secrets.toml
key = "..." # your Mistral api key
```
(you can obtain a Mistral key from [here](https://console.mistral.ai/api-keys))
### Codestral
To use Codestral model with Codestral, for example, set:
```toml
[config] # in configuration.toml
model = "codestral/codestral-latest"
fallback_models = ["codestral/codestral-2405"]
[codestral] # in .secrets.toml
key = "..." # your Codestral api key
```
(you can obtain a Codestral key from [here](https://console.mistral.ai/codestral))
### Openrouter
To use model from Openrouter, for example, set:
```toml
[config] # in configuration.toml
model="openrouter/anthropic/claude-3.7-sonnet"
fallback_models=["openrouter/deepseek/deepseek-chat"]
custom_model_max_tokens=20000
[openrouter] # in .secrets.toml or passed an environment variable openrouter__key
key = "..." # your openrouter api key
```
(you can obtain an Openrouter API key from [here](https://openrouter.ai/settings/keys))
### Custom models
If the relevant model doesn't appear [here](https://github.com/Codium-ai/pr-agent/blob/main/pr_agent/algo/__init__.py), you can still use it as a custom model:
1. Set the model name in the configuration file:
```toml
[config]
model="custom_model_name"
fallback_models=["custom_model_name"]
```
2. Set the maximal tokens for the model:
```toml
[config]
custom_model_max_tokens= ...
```
3. Go to [litellm documentation](https://litellm.vercel.app/docs/proxy/quick_start#supported-llms), find the model you want to use, and set the relevant environment variables.
4. Most reasoning models do not support chat-style inputs (`system` and `user` messages) or temperature settings.
To bypass chat templates and temperature controls, set `config.custom_reasoning_model = true` in your configuration file.
## Dedicated parameters
### OpenAI models
```toml
[config]
reasoning_efffort= = "medium" # "low", "medium", "high"
```
With the OpenAI models that support reasoning effort (eg: o4-mini), you can specify its reasoning effort via `config` section. The default value is `medium`. You can change it to `high` or `low` based on your usage.
### Anthropic models
```toml
[config]
enable_claude_extended_thinking = false # Set to true to enable extended thinking feature
extended_thinking_budget_tokens = 2048
extended_thinking_max_output_tokens = 4096
```

The different tools and sub-tools used by Qodo Merge are adjustable via the **[configuration file](https://github.com/Codium-ai/pr-agent/blob/main/pr_agent/settings/configuration.toml)**.
In addition to general configuration options, each tool has its own configurations. For example, the `review` tool will use parameters from the [pr_reviewer](https://github.com/Codium-ai/pr-agent/blob/main/pr_agent/settings/configuration.toml#L16) section in the configuration file.
See the [Tools Guide](https://qodo-merge-docs.qodo.ai/tools/) for a detailed description of the different tools and their configurations.
There are three ways to set persistent configurations:
1. Wiki configuration page 💎
2. Local configuration file
3. Global configuration file 💎
In terms of precedence, wiki configurations will override local configurations, and local configurations will override global configurations.
!!! tip "Tip1: edit only what you need"
Your configuration file should be minimal, and edit only the relevant values. Don't copy the entire configuration options, since it can lead to legacy problems when something changes.
!!! tip "Tip2: show relevant configurations"
If you set `config.output_relevant_configurations=true`, each tool will also output in a collapsible section its relevant configurations. This can be useful for debugging, or getting to know the configurations better.
## Wiki configuration file 💎
`Platforms supported: GitHub, GitLab, Bitbucket`
With Qodo Merge, you can set configurations by creating a page called `.pr_agent.toml` in the [wiki](https://github.com/Codium-ai/pr-agent/wiki/pr_agent.toml) of the repo.
The advantage of this method is that it allows to set configurations without needing to commit new content to the repo - just edit the wiki page and **save**.
![wiki_configuration](https://codium.ai/images/pr_agent/wiki_configuration.png){width=512}
Click [here](https://codium.ai/images/pr_agent/wiki_configuration_pr_agent.mp4) to see a short instructional video. We recommend surrounding the configuration content with triple-quotes (or \`\`\`toml), to allow better presentation when displayed in the wiki as markdown.
An example content:
```toml
[pr_description]
generate_ai_title=true
```
Qodo Merge will know to remove the surrounding quotes when reading the configuration content.
## Local configuration file
`Platforms supported: GitHub, GitLab, Bitbucket, Azure DevOps`
By uploading a local `.pr_agent.toml` file to the root of the repo's default branch, you can edit and customize any configuration parameter. Note that you need to upload or update `.pr_agent.toml` before using the PR Agent tools (either at PR creation or via manual trigger) for the configuration to take effect.
For example, if you set in `.pr_agent.toml`:
```
[pr_reviewer]
extra_instructions="""\
- instruction a
- instruction b
...
"""
```
Then you can give a list of extra instructions to the `review` tool.
## Global configuration file 💎
`Platforms supported: GitHub, GitLab, Bitbucket`
If you create a repo called `pr-agent-settings` in your **organization**, its configuration file `.pr_agent.toml` will be used as a global configuration file for any other repo that belongs to the same organization.
Parameters from a local `.pr_agent.toml` file, in a specific repo, will override the global configuration parameters.
For example, in the GitHub organization `Codium-ai`:
- The file [`https://github.com/Codium-ai/pr-agent-settings/.pr_agent.toml`](https://github.com/Codium-ai/pr-agent-settings/blob/main/.pr_agent.toml) serves as a global configuration file for all the repos in the GitHub organization `Codium-ai`.
- The repo [`https://github.com/Codium-ai/pr-agent`](https://github.com/Codium-ai/pr-agent/blob/main/.pr_agent.toml) inherits the global configuration file from `pr-agent-settings`.
### Bitbucket Organization level configuration file 💎
`Relevant platforms: Bitbucket Data Center`
In Bitbucket Data Center, there are two levels where you can define a global configuration file:
- Project-level global configuration:
Create a repository named `pr-agent-settings` within a specific project. The configuration file in this repository will apply to all repositories under the same project.
- Organization-level global configuration:
Create a dedicated project to hold a global configuration file that affects all repositories across all projects in your organization.
**Setting up organization-level global configuration:**
1. Create a new project with both the name and key: PR_AGENT_SETTINGS.
2. Inside the PR_AGENT_SETTINGS project, create a repository named pr-agent-settings.
3. In this repository, add a `.pr_agent.toml` configuration file—structured similarly to the global configuration file described above.
4. Optionally, you can add organizational-level [global best practices file](https://qodo-merge-docs.qodo.ai/usage-guide/configuration_options/#global-configuration-file).
Repositories across your entire Bitbucket organization will inherit the configuration from this file.
!!! note "Note"
If both organization-level and project-level global settings are defined, the project-level settings will take precedence over the organization-level configuration. Additionally, parameters from a repositorys local .pr_agent.toml file will always override both global settings.

`Supported Git Platforms: GitHub, GitLab, Bitbucket`
For optimal functionality of Qodo Merge, we recommend enabling a wiki for each repository where Qodo Merge is installed. The wiki serves several important purposes:
**Key Wiki Features: 💎**
- Storing a [configuration file](https://qodo-merge-docs.qodo.ai/usage-guide/configuration_options/#wiki-configuration-file)
- Track [accepted suggestions](https://qodo-merge-docs.qodo.ai/tools/improve/#suggestion-tracking)
- Facilitates learning over time by creating an [auto_best_practices.md](https://qodo-merge-docs.qodo.ai/core-abilities/auto_best_practices) file
**Setup Instructions (GitHub):**
To enable a wiki for your repository:
1. Navigate to your repository's main page on GitHub
2. Select "Settings" from the top navigation bar
3. Locate the "Features" section
4. Enable the "Wikis" option by checking the corresponding box
5. Return to your repository's main page
6. Look for the newly added "Wiki" tab in the top navigation
7. Initialize your wiki by clicking "Create the first page" and saving (this step is important - without creating an initial page, the wiki will not be fully functional)
### Why Wiki?
- Your code (and its derivatives, including accepted code suggestions) is yours. Qodo Merge will never store it on external servers.
- Repository changes typically require pull requests, which create overhead and are time-consuming. This process is too cumbersome for auto data aggregation, and is not very convenient even for managing frequently updated content like configuration files.
- A repository wiki page provides an ideal balance:
- It lives within your repository, making it suitable for code-related documentation
- It enables quick updates without the overhead of pull requests
- It maintains full Git version control, allowing you to track changes over time.
