Implements strict type safety and runtime validation using modern TypeScript 5.5+ features and Zod schemas.
The TypeScript Fieldguide skill equips Claude with specialized knowledge to write high-quality, production-grade TypeScript code. It focuses on eliminating the 'any' type in favor of 'unknown' and type guards, implementing robust runtime validation with Zod, and utilizing modern features like inferred type predicates and explicit resource management. By promoting the Result pattern for error handling and branded types for domain modeling, this skill ensures your codebase is both type-safe at compile-time and resilient at runtime.
