Diagnose and recover broken Git state and worktree metadata with a staged, low-risk recovery flow. Use when Git reports detached or contradictory HEAD state, phantom worktree locks, orphaned worktree entries, missing refs, 0000000000000000000000000000000000000000 hashes, or branch operations fail with errors like already checked out, unknown revision, not a valid object name, or cannot lock ref.

Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Then review README.md for any prerequisites, environment setup, or post-install checks. Tell me what you changed and call out any manual steps you could not complete.
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Then review README.md for any prerequisites, environment setup, or post-install checks. Summarize what changed and any follow-up checks I should run.
Recover a repo without making the blast radius worse.
Snapshot first. Do not "just try stuff." Prefer non-destructive fixes before force operations. Treat .git/ as production data until backup is taken. Use git symbolic-ref before manually editing .git/HEAD. After each fix, run verification before proceeding.
Capture diagnostics: bash scripts/snapshot_git_state.sh . Route by symptom using references/symptom-map.md. Generate non-destructive command plan: bash scripts/guided_repair_plan.sh --repo . Apply the smallest matching playbook. Run references/recovery-checklist.md verification gate. Escalate only if the gate fails. For explicit routing: bash scripts/guided_repair_plan.sh --list bash scripts/guided_repair_plan.sh --symptom phantom-branch-lock
Use disposable simulation tests before changing script logic: bash scripts/regression_harness.sh Run one scenario: bash scripts/regression_harness.sh --scenario orphaned-worktree
Symptoms: git worktree list shows a path that no longer exists. Worktree entries include invalid or zero hashes. Steps: git worktree list --porcelain git worktree prune -v git worktree list --porcelain If stale entries remain, back up .git/ and remove the specific stale folder under .git/worktrees/<name>, then rerun prune.
Symptoms: git branch -d or git branch -D fails with "already used by worktree". git worktree list seems to disagree with branch ownership. Steps: git worktree list --porcelain Find the worktree using that branch, switch that worktree to another branch or detach HEAD there, then retry the branch operation in the main repo.
Symptoms: git status says detached HEAD unexpectedly. git branch --show-current and git symbolic-ref -q HEAD disagree. Steps: git symbolic-ref -q HEAD || true git reflog --date=iso -n 20 git switch <known-good-branch> If branch context is unknown, create a rescue branch from current commit: git switch -c rescue/$(date +%Y%m%d-%H%M%S) Then reconnect to the intended branch after investigation.
Symptoms: unknown revision, not a valid object name, or cannot lock ref. Steps: git fetch --all --prune git show-ref --verify refs/remotes/origin/<branch> git branch -f <branch> origin/<branch> git switch <branch> Use reflog to recover local-only commits before forcing branch pointers.
Only after backup of .git/. Preferred: git show-ref --verify refs/heads/<branch> git symbolic-ref HEAD refs/heads/<branch> Fallback when symbolic-ref cannot be used: echo "ref: refs/heads/<branch>" > .git/HEAD Immediately run the verification gate.
Run checks in references/recovery-checklist.md. Minimum bar: git status exits cleanly with no fatal errors. git symbolic-ref -q HEAD matches intended branch. git worktree list --porcelain has no missing paths and no zero hashes. git fsck --no-reflogs --full has no new critical errors.
Archive .git: tar -czf git-metadata-backup-$(date +%Y%m%d-%H%M%S).tar.gz .git Clone fresh from remote. Recover unpushed work with reflog and cherry-pick from old clone. Document failure mode and add guardrails to automation.
When building worktree tooling (iMi, scripts, bots), enforce: preflight snapshot and state validation post-operation verification gate hard stop on HEAD/ref inconsistency explicit user confirmation before destructive commands
