​
Configuration methods

Add tools to your repository’s .coderabbit.yaml file:
YAML
reviews:
  profile: assertive
  tools:
    eslint:
      enabled: true
    ruff:
      enabled: true
      config_file: "pyproject.toml"
    gitleaks:
      enabled: true
Use reviews.tools.<tool>.enabled to enable or disable individual tools. The optional config_file field points to your existing tool-specific configuration file (for example .eslintrc.js or pyproject.toml), letting you control which rules are active and their severity.

​
Tool profiles

CodeRabbit offers two review profiles that control tool strictness:
  • Chill: Focuses on critical issues and reduces noise from minor style violations
  • Assertive: Provides comprehensive feedback including style and best practice suggestions
Each tool respects your existing configuration files (like .eslintrc.js or pyproject.toml) for maximum customization.

​
Tool output and fixes

When tools detect issues, CodeRabbit attaches structured output under the “Review details” comment in your pull or merge request. Each entry shows the file path, line number, and the issue detected: 
ESLint
src/components/Button.tsx
12-12: 'React' must be in scope when using JSX

Add React import statement

(react/react-in-jsx-scope)
Many tools provide 1-click fixes that CodeRabbit can apply directly to your pull request, streamlining the review process.
