# Plan Review Gate ## Overview Three independent adversarial reviewers validate any implementation plan before it is presented to the user. Each reviews independently with no shared context. ## When to Use - After the Architect creates an implementation plan - Before presenting a plan for user approval - When validating work unit decomposition quality ## Process 1. **Feasibility Reviewer** - Can this plan actually be implemented? Technical viability, resource requirements, timeline reality 2. **Completeness Reviewer** - Does the plan cover everything? Missing edge cases, untested paths, incomplete DoD items 3. **Scope & Alignment Reviewer** - Does the plan match the issue? Scope creep detection, requirement traceability All 3 must PASS before the plan is presented. ## Key Rules - Reviewers operate independently (no shared context) - Each provides a binary PASS/FAIL verdict - Findings include specific references to plan sections - Failed plans require revision before re-review ## Tool Use Invoke as part of: `methodologies/metaswarm/metaswarm-orchestrator` (Phase 1b)
