What problem does it solve? Long-running software implementation work often drifts from its approved plan: repository state changes silently, steps get marked done without evidence, and deviations are absorbed without record. This Skill enforces a disciplined execution loop that keeps the plan, repository state, and validation evidence continuously reconciled. ## Core Features & Use Cases - State Rehydration & Drift Detection: On every session, re-reads the plan, checkpoints, and handoff snapshot, then compares them against actual Git state to classify drift as compatible, plan-relevant, or unknown. - Explicit Conformance Classification: Every change is classified as CONFORMING, LOCAL_VARIATION, PLAN_GAP, DEVIATION_REQUIRED, PLAN_INVALID, BLOCKED, or OUT_OF_SCOPE, preventing silent redesign and scope creep. - Checkpoint & Handoff Lifecycle: Creates sequential checkpoints with validation evidence, maintains a compliance matrix, and produces resumable handoff snapshots so another agent can continue without conversational memory. - Use Case: A team maintains a multi-milestone refactoring plan under docs/public/plans/active/. An agent executing it across several sessions uses this Skill to resume safely after interruptions, prove each step with test evidence, and archive the plan when complete. ## Quick Start Execute the active plan in docs/public/plans/active/ and continue from its latest checkpoint, verifying repository state before making any changes.
