| description.long | A code review platform combining 5,000+ deterministic analysis rules with AI agents to automatically detect security vulnerabilities, bugs, and quality issues in pull requests without requiring CI setup. | 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. |
