typescript

Guidance for measuring TypeScript type instantiations using @ark/attest. Use when optimizing type-level performance, writing type benchmarks, or debugging slow type evaluation.

Creates structured domain documentation with anatomy diagrams, entity schemas, and operation specs. Use when designing systems, after brainstorming, or documenting existing architecture.

Explore npm package source code locally. Use when needing to understand a library's API, types, or implementation.

Formatting rules for TypeScript conditional types. Use when writing complex conditional types to ensure debuggable, maintainable formatting with proper alignment.

Type parameter naming conventions for personal TypeScript projects. Triggers on generic type/function creation, type-level code, or when asking about TypeScript generics.

This skill should be used when the user asks to "add JSDoc", "document this function", "write JSDoc comments", "link to a type", "use @link tag", "hyperlink in JSDoc", "reference external service in docs", or needs guidance on JSDoc syntax, clickable type references, or TypeScript-optimized documentation.

TypeScript testing conventions and TDD practices. Use when writing tests, fixing bugs, or organizing test files.
