typescript-type-toolkit

Coaches the agent through TypeScript's compile-time type system so it can write and refactor type-safe code with confidence. Covers generics with constraints, conditional types with infer, mapped types with key remapping, template literal types, the built-in utility types, and runtime narrowing with type guards, assertion functions, and discriminated unions. Includes recipes for typed event buses, deep partial updates, per-field validators, and recursive string path types, plus habits that keep compilation fast. Use when writing or reviewing TypeScript that needs compile-time guarantees, building reusable generic utilities, or diagnosing stubborn type errors. Not for runtime JavaScript behavior, bundler or tsconfig setup beyond strict mode, or framework-specific typing questions.
