What problem does it solve? Executing a multi-task implementation plan in one session pollutes context, loses progress after compaction, and ships unreviewed code. This Skill orchestrates plan execution through isolated subagents with per-task reviews and a persistent ledger. ## Core Features & Use Cases - Fresh subagent per task: Dispatch an implementer subagent with a task brief file, keeping the controller's context clean for coordination. - Two-stage review loop: Run a spec-compliance and code-quality review after every task, plus a final whole-branch review, with a bounded five-round fix loop and escalation to more capable models. - Crash-safe progress ledger: Track completed tasks, fix rounds, and parked findings in a per-plan workspace so work resumes correctly after context compaction. - Use Case: Given a written implementation plan with eight independent tasks, execute all of them in the current session — each implemented, tested, reviewed, and committed — then finish the development branch. ## Quick Start Execute the implementation plan at docs/plans/feature-plan.md using subagent-driven development, dispatching an implementer and reviewer for each task.
