Red Knot

Red Knot is an extremely fast type checker. Currently, it is a work-in-progress and not ready for user testing.

Red Knot is designed to prioritize good type inference, even in unannotated code, and aims to avoid false positives.

While Red Knot will produce similar results to mypy and pyright on many codebases, 100% compatibility with these tools is a non-goal. On some codebases, Red Knot's design decisions lead to different outcomes than you would get from running one of these more established tools.

Core type checking tests are written as Markdown code blocks. They can be found in red_knot_python_semantic/resources/mdtest. See red_knot_test/README.md for more information on the test framework itself.
