What problem does it solve? Executing an approved implementation plan involves many error-prone steps: setting up isolated worktrees, resuming in-flight work, running the right tests at the right time, triaging failures, and creating compliant pull requests. This Skill orchestrates that entire lifecycle so approved plans are executed consistently without losing context or polluting the main workspace. ## Core Features & Use Cases - Topology Discovery & Resume: Automatically detects whether a task runs in a fresh worktree, an in-flight worktree, or in-tree on develop, and resumes from the first unchecked task. - Red/Green/Refactor Phase Loops: Enforces test-first development with tiered verification rings (fast sliced tests, phase gates, full multi-database matrix) and three-tier failure triage that quarantines pre-existing baseline rot. - PR Lifecycle Management: Handles semantic phase commits, pre-PR rebases, Release Impact checklist generation, worktree parking for CI follow-up, and teardown on user confirmation. - Use Case: After approving a plan in dev/active/<task>/, tell the agent to execute it; the Skill creates an isolated worktree, implements each phase with tests, commits semantically, and opens a compliant PR to develop. ## Quick Start Execute the approved task plan in dev/active/my-feature using the implement-tasks workflow and open a pull request when finished.
