+# Python Coding Rules for PR Agent
+
+## Code Style
+- Follow Python PEP 8 style guidelines
+- Use 4 spaces for indentation (never tabs)
+- Line length should not exceed 120 characters
+- Use double quotes for strings unless single quotes avoid escaping
+- Add trailing commas in multi-line data structures
+
+## Naming Conventions
+- Use snake_case for variables, functions, and module names
+- Use PascalCase for class names
+- Use UPPER_SNAKE_CASE for constants
+- Prefix private methods and attributes with underscore
+
+## Type Hints and Documentation
+- Always use type hints for function parameters and return values
+- Use docstrings for all public functions and classes
+- Use Google-style docstrings format
+- Include type information in docstrings when not obvious
+
+## Python Best Practices
+- Prefer f-strings over .format() or % formatting
+- Use pathlib.Path instead of os.path for file operations
+- Always handle exceptions explicitly, avoid bare except clauses
+- Use specific exception types instead of generic Exception
+
+## Patterns to Avoid
+- Don't use global variables
+- Avoid nested functions with more than 2 levels
+- Don't leave print() statements in production code
+- Never commit TODO comments without GitHub issues
+- Avoid importing * (star imports)
+
+## Error Handling
+- Always log errors with appropriate context
+- Use try/except blocks close to the failing operation
+- Prefer early returns to reduce nesting
+
+## Testing
+- Write unit tests for all new functions
+- Use descriptive test method names
+- Follow AAA pattern: Arrange, Act, Assert
+- Mock external dependencies in tests

+## 📐 Cursor Rules Support
+
+The bot automatically detects and respects official Cursor rules in your repository, ensuring AI reviews follow your project's specific coding standards.
+
+### Supported Rules Files
+
+The bot looks for these official Cursor rules files:
+
+**Current Format (Recommended):**
+- `.cursor/rules/*.mdc` - Modern Cursor project rules files
+
+**Legacy Format (Deprecated but supported):**
+- `.cursorrules` - Legacy Cursor rules file
+
+### Example Rules File
+
+Create `.cursor/rules/style.mdc` in your repository:
+
+```markdown
+---
+description: Code style and formatting rules
+alwaysApply: true
+---
+
+# Project Coding Rules
+
+## Code Style
+- Use 2 spaces for indentation
+- Prefer const over let when possible
+- Always use semicolons
+- Use single quotes for strings
+
+## Naming Conventions
+- Use camelCase for variables and functions
+- Use PascalCase for classes and components
+- Use UPPER_SNAKE_CASE for constants
+
+## Patterns to Avoid
+- Don't use console.log in production code
+- Avoid nested ternary operators
+- Never commit commented-out code
+
+## Preferred Patterns
+- Use TypeScript strict mode
+- Prefer async/await over promises.then()
+- Use destructuring for object properties
+```
+
+The bot will automatically include these rules in its analysis, ensuring consistent code reviews that match your project's standards.
