What problem does it solve? Reviewing implementation plans by hand is inconsistent: reviewers miss risk domains, repeat already-resolved findings, and return free-form feedback that automated pipelines cannot validate. This Skill turns plan review into a deterministic, schema-validated JSON critique that an orchestration loop can consume directly. ## Core Features & Use Cases - Schema-conformant critique output: Emits JSON only, conforming to critique.schema.json, with domain assessments, issues, boundary challenges, and opportunities. - Eight fixed readiness domains: Classifies correctness, public-compatibility, data-migrations, security, concurrency, cross-repository delivery, operability, and performance with applicability and risk levels. - Bounded issue budget with lineage: Reports at most 8 material blocker/major issues, each with evidence, severity, confidence, and versioned parent references (vN.Cm) to avoid repeating resolved findings. - Use Case: Inside the agent-quorum plan → critique → update loop, the critic reviews plan.v2.md, verifies file references via targeted reads, and returns a validated JSON critique that decides whether the plan needs another revision. ## Quick Start Ask the agent to critique the current implementation plan and return only JSON conforming to critique.schema.json with domain assessments and material issues.
