What problem does it solve? Autonomous QA pipelines can silently compress scope at phase transitions — skipping phases, stopping early, or accepting incomplete deliverables. This Skill gates every phase, pass, and cycle transition of the Achilles onboarding, coverage-expansion, journey-mapping, and perf-onboarding pipelines by reviewing the closing handover against canonical methodology exit criteria before the orchestrator may advance. ## Core Features & Use Cases - Transition gating: Dispatched as a subagent at every phase (1-8), coverage pass, journey-mapping cycle, and perf-onboarding phase/pass boundary, returning a structured verdict of approve, reject, or escalate per the workflow-reviewer.schema.json contract. - Checklist-driven review: Converts each methodology section into yes/no checklist items with evidence and methodology references, covering scaffold, groundwork, happy-path, journey-mapping, coverage, bug-discovery, secrets-sweep, report, and k6 performance phases. - 3-cycle reject cap and skip authorization: Enforces a maximum of three review cycles per unit before escalating to the user, and acts as the only legitimate path for approving phase skips or early stops when an explicit authorizer is present. - Use Case: After Phase 3 of an onboarding run completes, the orchestrator dispatches workflow-reviewer-phase3 with the ledger, handover envelope, and deliverables; the reviewer verifies one passing spec per primary journey and the discovery-draft sentinel, then returns an approve verdict or surgical fix instructions. ## Quick Start Dispatch the workflow-reviewer-phase3 subagent with the onboarding ledger, the Phase 3 methodology section, and the closing handover envelope to verify the happy-path exit criteria before advancing.
