How does it handle external API data?

It requires all external data to be validated at the boundary using schema libraries like Zod or Valibot, ensuring 'any' never enters your application logic.

Does this skill support function declarations?

It specifically prefers arrow functions for consistency and safer lexical 'this' binding, treating them as the project standard.

Why does this skill ban the 'as' keyword?

The 'as' keyword bypasses TypeScript's type-checker, often masking underlying logic errors. This skill prefers fixing root causes through type guards or signature refinement.

What is 'as const satisfies' used for?

It is used to preserve exact literal types for configurations and constants while ensuring they conform to a specific interface without widening to 'string' or 'number'.

What happens when a type error is too complex for the AI?

Instead of using 'any', the skill documents the limitation, leaves the error for manual review, and notifies the user to prevent introducing type-unsoundness.

Enforces rigorous type-level verification and compile-time safety to eliminate runtime bugs in TypeScript projects.

This skill transforms Claude into a strict TypeScript architect focused on the philosophy that 'if it type-checks, it works.' It enforces high-integrity coding patterns by prohibiting unsafe 'as' assertions, mandating runtime validation for external data, and utilizing advanced features like discriminated unions and 'satisfies' operators. By shifting the burden of proof from runtime tests to the type system, this skill ensures more predictable, maintainable, and bug-free codebases.
