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 displays structured output in the review comments: 
ESLint
src/components/Button.tsx
12-12: 'React' must be in scope when using JSX
