What problem does it solve? Executing a multi-phase implementation plan by hand means juggling worktrees, code reviews, feedback triage, and merge discipline manually, with no durable record of progress if work is interrupted. This Skill orchestrates the entire per-phase execution lifecycle so an approved plan lands incrementally with validated, reviewable diffs. ## Core Features & Use Cases - Sequential phase orchestration: Parses the plan's tasks.md, resumes from the first unchecked phase, and never starts phase N+1 before phase N merges. - Worktree-managed code dispatch: Creates a named git worktree per phase, dispatches /write-code workers into it, and validates the phase diff with /validate-code using contextual reviewers (security, performance, integration). - Convergence loop: Drives the triage-feedback / process-feedback / lock-decisions cycle until a validation pass returns no actionable clusters, then fast-forward merges and checks off tasks.md. - Use Case: A captain says "execute p018" — the Skill reads the plan, lands each phase in its own worktree with validated diffs, updates tasks.md after every merge, and stops with a summary of landed SHAs and deferred items. ## Quick Start Ask the agent to execute plan p018 and it will walk each phase through worktree setup, code dispatch, validation, and merge until the plan's tasks are all checked off.
