| description.long | A type analysis tool for Python that enables code to transition from pure dynamic typing to statically-typed code through annotations, with error detection at check time. Code runs with negligible performance impact and developers can incrementally adopt static types in existing projects. | A code quality platform that automatically analyzes pull requests for linting, formatting, security issues, and code coverage with AI-generated fixes. Supports 40+ languages and integrates with GitHub, IDEs, and CI systems. |
