What problem does it solve? Work can drift from its original goal, and an agent's self-report of having checked something is not proof. This Skill acts as a formal phase gate that compares the intent, plan, and execution artifacts against each other and actively re-checks every load-bearing claim against its source before you proceed. ## Core Features & Use Cases - Three-artifact drift check: Compares the original intent, the plan, and the actual execution, citing specific evidence for any gaps, drifts, or issues found. - Active per-claim source re-check: Re-opens the source for every load-bearing factual claim, including checking the committed blob or built artifact rather than the mutable working tree. - Structured verdict output: Produces a verdict with clean, gaps, drifts, issues, and a status of clean, gaps-found, plan-not-found, incomplete, or unverified, plus routing to the next step. - Use Case: Before merging a feature branch, run the gate to confirm the committed code actually matches the plan and intent, catching cases where the working tree looks fine but the committed HEAD is broken. ## Quick Start Run /verify to check whether my intent, plan, and execution still align before I move to the next phase.
