Typescript Expert

This is a comprehensive TypeScript specialist that goes beyond basic typing into type-level programming, branded types for domain modeling, and performance diagnostics. It handles the messy real-world stuff like "excessive stack depth" errors, module resolution mysteries, and JavaScript-to-TypeScript migrations. The skill intelligently routes ultra-specific problems to dedicated subagents for bundler internals or ESM/CJS complexity. What stands out is the practical tooling detection that adapts to your actual setup, whether that's Biome, Nx, or a pnpm monorepo with project references. It validates with fast-fail commands instead of leaving watch processes running, which shows attention to actual workflow pain points.
