Claims verifier

One cold adversarial pass over a document, claim by claim. The reviewer is a fresh subagent invocation; it attempts to refute every factual and logical claim and returns a verdict for each. Nothing is edited in a pass — revision happens only through the author's dispositions between passes. The skill is self-contained: the standards it enforces are stated here rather than delegated to a guide.

Partner to senior-code-review: that skill holds code to the craft, this one holds prose to its evidence. The burden of proof sits with the document — a claim stands because a cited source carries it, or because it follows validly from supported premises, never because it sounds right. The line holds even for commonplaces: an unsourced truism is still UNSUPPORTED, and the author retires it with a disposition rather than the adversary waving it through on shared knowledge.

Throughout, the author is the human who owns the document and declares the review converged; the orchestrator is the session running this loop.

Contents

• Why a subagent and not this session (46) — the structural-independence rule.
• Inputs the adversary gets (58) — source-list entry forms, identity line, standing section.
• Where the record lives (224) — claims-review.md; the three content kinds.
• One hash identity (335) — the three spawn hashes; the content-addressed snapshot store.
• Running requirements (364) — the claims-auditor agent to install; the assurance ladder (sealed · quarantined-clone · adversary-only).
• The loop (431)
  • 1. Resolve inputs, check them, assurance preflight (433)
  • 1. Audit the pass — the seven checks (501): Coverage, Attestations, Segmentation, Support, Reconciliation, Stability, Merits (655+)
  • 1. Work the findings — fix / accept / reject / contest (1181)
  • 1. UNVERIFIABLE → author fetch (1376)
  • 1. Apply fixes, run the next pass (1390)
  • 1. Converged — predicates, streak, declaration, certification invocation, cross-party draw (1392)
• Running a pass (1620) — spawn shape; the verbatim adversary prompt follows (1649).
