What Claim Verify Loop does

Claim Verify Loop checks each discrete claim in a results draft against the underlying dataset, then stress-tests it for outliers, confounds, and subgroup effects. Use it before publishing when a data-backed draft needs adversarial verification and revision.

Claim Verify Loop is cataloged under AI Engineering on DirSkills. Claim Verify Loop comes from a repository tagged agent-skills, agentic-loops, agentic-workflows, ai-agents and anthropic.

Excerpt

Claim Verify Loop

A claim-by-claim adversarial verification loop over a results draft. The artifact is the draft; the feedback signal is the count of unverified claims — claims not yet checked, or checked but not yet survived a stress test. You drive it to zero: each claim ends verified (reproduces and survives the obvious threats) or appropriately qualified (hedged, scoped, or retracted with the reason).

The discipline: a number that merely reproduces is not trustworthy — most wrong findings reproduce fine. A claim is verified only when it also survives the threat most likely to kill it: an outlier, a confound, a subgroup too small to mean anything, a sign that flips under stratification. This loop is a gate on an existing draft, not a generator of new findings.

This is the opening of the README. Read the full README on GitHub.
