#documentation

Complete JSDoc or docstrings with precise types, throws, constraints, and a usage example.

Update docs strictly from the diff, with no invented features.

A typed, documented function built to spec — with three unit tests covering the edge and error cases.

Turn a diff into a scannable PR write-up with risks, rollback, and a reviewer checklist.

A no-fluff README with only the sections your project actually needs filled in.

Generate clear docs for a chunk of code — overview, parameters, usage, and gotchas.
