Use when reviewing a prose document — KB article, RFC, spike, runbook, PRD, design doc, knowledge-base page — hosted on Google Docs, Confluence, a local file path, or an arbitrary URL. Checks correctness, internal consistency, audience-fit, prose clarity, and external-claim verification; cross-checks against existing platform comments to avoid re-flagging; returns severity-tagged findings with anchor + quote + concrete fix. Use when asked to "review this doc / KB / RFC / spike / runbook / PRD" and the target is prose, not a code diff. Counterpart to the write-spike skill. NOT for code diffs — use /devflow:review for those.
