How does it handle type narrowing?

It provides best practices for 'typeof', 'instanceof', and 'in' operator narrowing, as well as custom type guards and assertion functions for complex logic.

Can it help with complex tsconfig.json setups?

Yes, it provides optimized configurations for strict null checks, module resolution for modern bundlers, and emission settings for library development.

Is this useful for refactoring existing projects?

Yes, it is specifically designed to help identify weak points in existing type definitions and refactor them into safer, more explicit structures.

Does it support advanced type manipulation?

Absolutely. It includes patterns for mapped types, conditional types using the 'infer' keyword, and template literal types for sophisticated string-based type logic.

How does this skill improve my TypeScript code?

It guides Claude to enforce strict mode, avoid 'any' types, and implement advanced patterns like discriminated unions to catch errors at compile-time rather than runtime.
