TypeScript Standards

Public APIs must feel like JavaScript. Callers write JS. You hide the type work. App or library does not change this.

This skill does not decide where a helper file lives. It does not add debug flags. It does not load other skills.

When To Use

Load when writing or reviewing TypeScript (.ts, .tsx). App code and library code both use these rules.

Skip test-only files, docs, and CSS.
