What problem does it solve? After intensive repository work, developers often leave behind stale branches, orphaned worktrees, old stashes, interrupted merges, untriaged PRs, and draft releases. This Skill audits all of that in one shot and presents a fixed-vocabulary status table with recommended actions, so nothing is silently forgotten. ## Core Features & Use Cases - 16-area health audit: Runs the health-check.mjs engine to check interrupted git operations, conflict markers, working tree, stash, local branches, remote tracking, worktrees, submodules, tags, open PRs, assigned issues, review requests, failed CI runs, draft releases, automation PRs, and perspective frontmatter consistency. - Deep investigation mode: With --deep, performs read-only follow-up on items marked 要確認, upgrading labels where machine-decidable (e.g., stash apply-check, branch cherry detection against trunk). - Safe auto-fix with policy gates: With --fix, executes only reversible-local actions (prune / delete / fetch) immediately, while irreversible actions like stash drop require individual confirmation unless --yes explicitly overrides the central policy. - Use Case: At the end of a work session, run the health check to discover a forgotten stash, two merged branches, and an orphaned agent worktree, then clean them up safely with --fix. ## Quick Start Ask the assistant to run the health skill to check the repository for leftover state and show the status table.
