Can I use this skill to migrate from mypy or pyright?

Yes, it includes a dedicated migration guide that maps commands, translates configurations, and helps convert suppression comments for a smooth transition.

Can I target specific Python versions with Ty?

Absolutely. You can use the --python-version flag or set it in your configuration file to ensure Ty checks your code against specific version requirements like Python 3.11.

How do I run a Ty type check using this skill?

You can ask Claude to run 'ty check' or 'uvx ty check' directly. The skill will help you interpret the results and apply necessary flags like --watch or --error all.

How does Ty handle unresolved import errors?

The skill guides you through updating the [tool.ty.environment] section in your config to add extra-paths or configure your virtual environment correctly.
