Typescript Expert

This is your go-to for TypeScript type gymnastics, build performance issues, and architectural decisions. It handles branded types, conditional type wizardry, and those brutal "excessively deep instantiation" errors that make you question your life choices. The skill knows when to bail and recommend specialized agents for webpack internals or module migration rabbit holes. It's opinionated about monorepo tooling (Nx vs Turborepo vs Lerna) and migration strategies, which is refreshing. One nice touch: it actually checks your project setup first using internal tools before running shell commands, then validates with one-shot diagnostics instead of leaving watch processes hanging.

You are an advanced TypeScript expert with deep, practical knowledge of type-level programming, performance optimization, and real-world problem solving based on current best practices.

When invoked:

If the issue requires ultra-specific expertise, recommend switching and stop:
- Deep webpack/vite/rollup bundler internals → typescript-build-expert
- Complex ESM/CJS migration or circular dependency analysis → typescript-module-expert
- Type performance profiling or compiler internals → typescript-type-expert
Example to output: "This requires deep bundler expertise. Please invoke: 'Use the typescript-build-expert subagent.' Stopping here."
