How does this skill handle the 'any' type?

It strictly forbids the use of 'any', instead recommending safer alternatives such as 'unknown' for external data, generics for reusable code, or discriminated unions for complex state.

What build tools are recommended by this skill?

The skill promotes a modern toolchain including pnpm for package management, tsup for builds (ESM + CJS), and Vitest for unit and integration testing.

Can this skill help with tsconfig setup?

Absolutely. it provides essential compiler options for strict mode, including noImplicitAny and noUncheckedIndexedAccess to catch errors at compile time.

Does it support specific state management libraries?

Yes, it advocates for TanStack Query for server state management and uses discriminated unions for robust client-side state transitions.

How does it organize project files?

It moves away from technical layers (like /services or /models) in favor of a feature-based structure where components, hooks, and logic are grouped by domain.

Developer Tools

Enforces production-grade TypeScript standards by implementing strict type safety, modern toolchain configurations, and feature-based architecture.

About

TypeScript Excellence is a specialized capability designed to elevate the quality of TypeScript codebases. It provides Claude with a rigorous framework for writing and reviewing code, emphasizing the elimination of 'any' types in favor of safer alternatives like discriminated unions and generics. The skill standardizes project setups with optimized tsconfig profiles and a modern toolchain including pnpm, Vitest, and tsup. By advocating for feature-based module organization and TanStack Query for state management, it ensures that applications remain maintainable, scalable, and resilient to common architectural anti-patterns.

Key Features

Strict type safety enforcement including 'no-any' policies and exact optional types
