+
+# Auto-fix linting errors
+ruff check . --fix
+
+# Format code
+ruff format .
+```
+
+**Guidelines:**
 - Follow PEP8 guidelines
 - Use type hints (Python 3.10+)
 - Write docstrings for public APIs
+- Line length: 120 characters
 - Keep code simple and readable
 
+All PRs must pass `ruff check .` before merging.
