What problem does it solve? It provides an independent, read-only challenge to Orchestrator decisions between the Define and Execute stages, catching scope errors, weak risk assessments, and unjustified routing before implementation begins. ## Core Features & Use Cases - Structured Challenge Points: Examines requirements contradictions, source-of-truth errors, runtime and integration choices, isolation claims, skipped assurance functions, and Hard Stop boundaries. - Four Verdicts: Returns APPROVE, APPROVE_WITH_CHANGES, RECONSIDER, or BLOCKED so the Orchestrator can resolve criticism with a clear decision path. - Trigger-Based Invocation: Activates when Stage 0 preflight completes, side-effect class is standard or above, new subagent topology is proposed, or 2+ skip reasons appear in one Work Block. - Use Case: After planning a multi-file refactor, invoke this review to verify the scope, skip reasons, and verification plan actually prove the acceptance criteria before any source writes occur. ## Quick Start Ask the agent to run a critic review of the completed Stage 0 Define output and return a verdict before starting Stage 1 Execute.
