How should I handle type ignores in Ty?

It is recommended to fix the underlying issue, but if necessary, use rule-specific comments like '# ty: ignore[rule-name]' instead of blanket tool-agnostic ignores.

Is Ty compatible with mypy configurations?

Ty provides a straightforward migration path from mypy; basic commands like 'mypy .' map directly to 'ty check', and strict modes can be toggled via CLI flags or configuration files.

How does Claude invoke Ty?

Claude typically uses 'uv run ty check' if Ty is a project dependency, or 'uvx ty check' for one-off analysis without installing it locally.

Ty is an extremely fast Python type checker and language server developed by Astral, intended to replace tools like mypy and Pyright with a more modern, high-performance solution.
