+### Controlling suggestions depth
+
+> `💎 feature`
+
+You can control the depth and comprehensiveness of the code suggestions by using the `pr_code_suggestions.suggestions_depth` parameter.
+
+Available options:
+
+- `selective` - Shows only suggestions above a score threshold of 6
+- `regular` - Default mode with balanced suggestion coverage  
+- `exhaustive` - Provides maximum suggestion comprehensiveness
+
+(Alternatively, use numeric values: 1, 2, or 3 respectively)
+
+We recommend starting with `regular` mode, then exploring `exhaustive` mode, which can provide more comprehensive suggestions and enhanced bug detection.
