SKILL.md

Just as you write tests for runtime code, you should write tests for your types. Type-level code can have bugs too, and type declarations can drift out of sync with implementations. Testing types ensures your declarations work correctly and catch the errors they should.

Type testing is particularly important for library authors, complex type utilities, and whenever types are defined separately from implementations.

Write tests for your types. Test that valid types work, invalid types fail, and the error messages are helpful.
