CommunityWrite TypeScript that stays safe in production.
System Documentation
What problem does it solve?
It prevents production failures caused by assuming compile-time TypeScript types also guarantee runtime safety when handling external data like HTTP bodies, SDK responses, browser storage, messages, and environment variables.
Core Features & Use Cases
- Strict, reviewable TypeScript configuration: Enforces strict mode with runtime-relevant safety flags to reduce undefined and unsafe indexing issues.
- Runtime boundary validation everywhere: Requires schema validation (zod/valibot/typebox) before data enters application state or crosses frontend/backend boundaries.
- Production-grade safety rules: Covers Promise handling discipline, discriminated state modeling, DTO separation, bundle-budget expectations, and accessibility guardrails.
Example use case: you are updating a frontend form that submits user input to an API and then renders the result; this Skill helps ensure every incoming/outgoing payload is validated and typed with DTO boundaries instead of trusting the wire format.
Quick Start
Use this capability when you are implementing or reviewing TypeScript changes that touch public APIs, frontend state, or any external boundary input.
