What problem does it solve? Open pull requests often stall mid-work: an automated run crashes, a human author stops halfway, or a PR arrives with no execution plan at all. This Skill resumes any open PR by claiming it safely, working in an isolated git worktree, and driving it to completion with validation, review, and label normalization. ## Core Features & Use Cases - Plan-based resume: Locates the PR's tracking plan, parses its Progress checklist, and continues implementation from the first unchecked step with per-phase commits and pushes. - PR adoption: When a PR has no execution plan, it reconstructs one from the PR description, comments, review feedback, linked issues, and diff, then commits it to the branch. - Concurrency-safe claiming: A three-signal in-progress check (assignee, label, claim comment) with stale-lock recovery and --force override prevents agents from clobbering each other. - Use Case: A nightly automation crashed after finishing phase 1 of PR #1492. Run the Skill with the PR number and it re-enters the worktree, resumes at step 2.1, runs the full validation gate and an autofix review pass, then flips the PR from draft to ready. ## Quick Start Ask the agent to resume pull request 1492 and finish its remaining plan steps.
