What problem does it solve? Multi-phase plans often contain hidden gaps, unstated assumptions, and future risks that only surface during execution. This Skill forces a phase-by-phase inspection with mandatory stops, so weaknesses are caught and amended before any work begins. ## Core Features & Use Cases - Iterative Phase Drill-Down: Walks every phase through gap, quality, and future-readiness assessments, never batching or skipping phases. - Verdict System: Assigns each phase a PASS, AMEND, or RETHINK verdict with a running verdict log cited in the final synthesis report. - User-Gated Amendments: Applies fixes to the plan artifact only after explicit user approval of named findings. - Use Case: After drafting a six-phase migration plan, run a deep dive to catch a missing rollback step in Phase 3 and an undeclared dependency in Phase 2 before execution starts. ## Quick Start Ask the agent to do a deep dive on the current implementation plan and inspect each phase for anything missing.
