| description.long | A comprehensive lint tool for Rust that identifies common coding mistakes, style issues, and performance problems, with configurable categories and levels of strictness. | A static type checker that analyzes Python code to catch type errors before runtime. Supports gradual typing, allowing you to mix static and dynamic typing and incrementally add type hints to existing codebases. |
