What typescript-pro does

This skill guides TypeScript work on shared contracts, complex generics, and stricter type checking. Its subject areas include conditional and mapped types, decorators, module organization, and projects using React, Node.js, or Express.

For a task, it first calls for defining runtime targets and strictness needs, then checking the implementation with compiler and lint safeguards. Suggested outputs include constrained generic functions, utility types, Jest or Vitest tests, and TSConfig adjustments. It is focused on TypeScript; its guidance does not fit a build pipeline where TypeScript cannot be enforced.

What it helps with

  • design shared TypeScript contracts
  • trace a generic constraint or inference issue
  • choose strict compiler options
  • add typed error handling
  • write .d.ts declarations for an external library

Example prompts for the agent

  • Trace why TypeScript infers the wrong type for this generic function.
  • Design shared types and contracts for the project modules.
  • Review the TSConfig settings and recommend stricter type checks.
