Writing and editing the yoink documentation in `docs/content/`. Use when the user asks to write, rewrite, tighten, de-AI, audit, or add a page under `docs/content/docs/{intro,start,guide,how-to,reference,examples,troubleshooting}`, or when modifying the Fumadocs + TanStack Start docs site. Enforces the de-AI prose playbook (information density, no hedges, no trope phrases), the Diátaxis structure the docs follow, the See-also convention, and the per-page word-count-delta verification protocol.
