docs-grounding-verifier

Run the grounding pipeline on the target page: extract atomic factual claims, retrieve evidence via deterministic grep over the source tree, then judge each claim-evidence tuple. You receive per-claim verdicts of GROUNDED, PARTIAL, CONTRADICTED, or UNSUPPORTED with file:line citations.

Claim-level verification adapts the RAGAS faithfulness-eval pattern to docs and code: each factual sentence in a page is checked individually against retrieved source evidence. This catches paragraph-level inaccuracies that page-level audit scores average over.

Use it when you have specific pages to fact-check, such as after editing a few pages or reviewing high-risk content. Whole-corpus sweeps belong to docs-corpus-audit, and PR-diff triage belongs to docs-sync; this skill handles 1..N pages at claim granularity.

No, it returns advisory verdicts only and never edits files. Contradicted or partial claims are handed to a doc-writer step as fix suggestions, and an optional alignment loop re-verifies pages after edits until the grounding rate reaches 0.9.

Evidence retrieval is fully deterministic: a shell script runs ripgrep or grep over the source tree using claim keywords, with no LLM involved. The judge can only rule on evidence actually retrieved, so it cannot invent supporting code.
