Fix for `git checkout <branch>` failing with `fatal: '<branch>' is already used by worktree at '.../autodocs-<name>'` (or a subagent reviewing a PR reports a path like `.../worktrees/autodocs-<topic>/...`). Use when: (1) right after a commit whose hook printed `[post-commit] Python files changed — running doc update in background...`, a later branch switch is blocked; (2) you can't check out the branch you just committed to because "another worktree" holds it; (3) a review/subagent cites a…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Async doc-update hook spawns an autodocs worktree that locks your branch
## Problem
This repo's async post-commit hook ("running doc update in background") materializes its own
git worktree (e.g. `.claude/worktrees/autodocs-<topic>`) and checks out the branch you just
committed to. Git only allows a branch to be checked out in ONE worktree, so a subsequent
`git checkout <that-branch>` in your main worktree fails:
```
fatal: '<branch>' is already used by worktree at
'/…/.claude/worktrees/autodocs-<topic>'
```
It also surfaces indirectly: a code-review subagent you pointed at the PR may report file
paths under `.../worktrees/autodocs-<topic>/...` — that's the hook's worktree, not yours.
## Context / Trigger conditions
- You committed on a feature branch; the commit output included
`[post-commit] Python files changed — running doc update in background...`.
- You then try to switch back to that branch (e.g. to apply a review fix) and git refuses.
- A subagent's review cites an `autodocs-*` path.
- Sibling symptom (different fix): the same hook also leaves `index.lock` behind →
`Unable to create '.git/worktrees/<name>/index.lock'` → that's `rm -f` (see See also).
## Solution
…Read the whole file at its exact version.
How to install
mdr add wan-huiyan/agent-traffic-control/async-doc-hook-autodocs-worktree-locks-branch-checkout@sha256:32d38a94bd3aeb43The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
