What problem does it solve?

TypeScript can become brittle without clear patterns. This Skill helps developers build robust TypeScript codebases by enforcing a type-first approach, explicit interfaces, and runtime validation with Zod to catch errors at compile-time and at run-time.

Core Features & Use Cases

• Type-First Development: Define types/interfaces before implementing logic to ensure correctness from the start.
• Type Safety Patterns: Use const assertions, discriminated unions, and branded types to prevent type leakage and improve maintainability.
• Runtime Validation with Zod: Define schemas first and infer TypeScript types, then validate external data safely, minimizing runtime surprises.
• Use Case: When integrating external APIs or validating user input in a TS project, this Skill provides concrete patterns and guidance.

Quick Start

Start by enabling strict mode in tsconfig.json, then define a type-first interface for a sample API response and validate it with a Zod schema.
