How does it improve project build performance?

The skill provides expert guidance on configuring tsconfig, project references, and incremental compilation to minimize build times and optimize bundle size.

Can it help with tRPC integration?

Yes, it provides specific implementation patterns for end-to-end type safety, helping you define type-safe contracts between your frontend and backend.

Does it support the latest TypeScript 5.0+ features?

Absolutely. It is optimized for the latest features including the satisfies operator, const type parameters, and improved decorator support.

How does this skill handle TypeScript strict mode?

It enforces strict mode by default, enabling all strict compiler flags and null checks to ensure maximum type safety and code reliability.
