What problem does it solve? Engineering teams marking specs as complete often rely on self-reported completion ledgers from the same agent that did the work, which invites performative claims and unchecked PARTIAL rows. This Skill provides an independent cold audit that verifies each acceptance criterion against real diff and test evidence before a spec flips to completed. ## Core Features & Use Cases - Evidence-based verification: Maps every acceptance criterion and Changes item to concrete diff hunks, test assertions, and file paths, downgrading DONE rows that lack evidence. - Structured verdict output: Produces a durable delivery-audit.md report on disk plus a machine-readable verdict block (SHIP or HOLD, clean or noteworthy) for the orchestrator. - PARTIAL and skip scrutiny: Assesses whether SKIPPED or BLOCKED reasons are concrete or vague, flagging soft skips that should block delivery. - Use Case: After a feature-delivery workflow finishes, invoke this auditor with the spec path, a git diff command, and the completion ledger to get an honest what-landed report before merging. ## Quick Start Ask the auditor to cold-audit the completed spec at a given path using a specified git diff command and the pasted completion ledger, then read the generated delivery-audit report.
