What problem does it solve? Executing a multi-task implementation plan in one AI session pollutes context, loses progress after compaction, and ships unreviewed code. This Skill orchestrates plan execution through isolated subagents, persistent ledgers, and enforced review gates so every task is implemented, tested, and verified. ## Core Features & Use Cases - Fresh subagent per task: Dispatches an implementer subagent with a task brief file, keeping the controller's context clean for coordination. - Two-stage review loop: Runs a spec-compliance and code-quality review after each task, plus a broad whole-branch review at the end, with a bounded five-round fix loop and adjudication rules. - Crash-safe progress ledger: Tracks task completion, fix rounds, and parked findings in a per-plan workspace so work resumes correctly after context compaction. - Use Case: You have a written implementation plan with eight independent tasks. This Skill dispatches an implementer for each task, reviews every diff, escalates stuck tasks to more capable models, and finishes with a whole-branch review before merging. ## Quick Start Use the subagent-driven-development skill to execute the implementation plan at docs/plans/feature-plan.md task by task with reviews.
