What problem does it solve? Flat or unstructured implementation plans lack checkpoints, making it hard to catch errors mid-execution or verify that prerequisites are met before risky actions. This Skill transforms any existing plan into a phased structure with explicit verification gates. ## Core Features & Use Cases - Phase Decomposition: Groups plan steps into independently verifiable phases with clear goals, ordered steps, and success criteria. - Verification Gates: Inserts /verify gates after every phase and around critical steps like schema migrations, breaking changes, and security-sensitive operations. - Safety Pre-Gates: Adds blocking pre-action gates for authorization, backup readiness, and destructive-target confirmation before mutations occur. - Use Case: You have a flat 20-step migration plan in implementation_plan.md. Run this Skill to split it into four phases, each ending with a concrete pass/fail verification gate, plus blocking checks before the destructive steps. ## Quick Start Ask the agent to add phases and verification gates to the current implementation plan using /phase-plan.
