Does it assist in migrating from JavaScript to TypeScript?

It offers a structured, incremental migration strategy using allowJs/checkJs flags and suggests tools like ts-migrate for automated conversion.

What advanced type patterns does it support?

It specializes in Branded Types for domain safety, deep recursive conditional types, and template literal types for type-safe event systems.

How does the TypeScript Expert skill improve build times?

It utilizes extended compiler diagnostics to identify slow-to-check files and suggests optimizations like replacing type intersections with interfaces and enabling incremental builds.

Can this skill help with complex monorepo setups?

Yes, it provides specific configurations for Nx and Turborepo, including setting up project references and managing shared tsconfig patterns.

How does it handle module resolution issues?

It provides deep diagnostics for ESM vs CJS interop, path mapping mysteries, and circular dependency analysis using specialized subagents.
