The `review` tool can be configured with extra instructions, which can be used to guide the model to 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 for extra instructions:
```
[pr_reviewer] # /review #
extra_instructions="""
In the code feedback section, emphasize the following:
- Does the code logic covers 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.

The `review` tool provides several type of feedbacks, one of them is code suggestions.
If you are interested **only** in the code suggestions, it is recommended to use the [`improve`](./IMPROVE.md) feature instead, since it dedicated only to code suggestions, and usually gives better results.
Use the `review` tool if you want to get a more comprehensive feedback, which includes code suggestions as well.

If you specify [custom labels](https://github.com/Codium-ai/pr-agent/blob/main/docs/DESCRIBE.md#handle-custom-labels-from-the-repos-labels-page-gem) in the repo's labels page or via configuration file, you can get tailored labels for your use cases.
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 list above is eclectic, and aims to give an idea of different possibilities. Define custom labels that are relevant for your repo and use cases.
Note that Labels are not mutually exclusive, so you can add multiple label categories.
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.
