JS/TS — detection

Declares when the js_ts profile activates on a given set of files. Consumed by klaude-plugin/skills/_shared/profile-detection.md. Multiple profiles may activate additively on the same diff.

The profile covers JavaScript and TypeScript jointly: review concerns (typing, async, modules, React patterns) overlap substantially, and the ecosystem tools (npm, bundlers, Node/browser runtimes) are shared.

Path signals

None. JS/TS detection does not use path heuristics; file extension alone is authoritative (see Content signals).

Filename signals

None. JS/TS detection is extension-based, not filename-based.

Content signals

A file activates the JS/TS profile if its extension is one of: .js, .jsx, .mjs, .cjs, .ts, .tsx, .mts, .cts. The extension match is authoritative; no byte-level content inspection is required.
