This file is byte-identical to the first copy the registry indexed, one of 7 indexed copies. Same content hash, so the same checks give both the same grade.
using-git-worktrees from ddtcorex/maestro-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
Use when starting feature work that needs isolation from current workspace or before executing implementation plans - ensures an isolated workspace exists via native tools or git worktree fallback.
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
# Using Git Worktrees
## Overview
Ensure work happens in an isolated workspace. Prefer your platform's native worktree tools. Fall back to manual git worktrees only when no native tool is available.
**Core principle:** Detect existing isolation first. Then use native tools. Then fall back to git. Never fight the harness.
**Announce at start:** "I'm using the using-git-worktrees skill to set up an isolated workspace."
## Step 0: Detect Existing Isolation
**Before creating anything, check if you are already in an isolated workspace.**
```bash
GIT_DIR=$(cd "$(git rev-parse --git-dir)" 2>/dev/null && pwd -P)
GIT_COMMON=$(cd "$(git rev-parse --git-common-dir)" 2>/dev/null && pwd -P)
BRANCH=$(git branch --show-current)
```
**Submodule guard:** `GIT_DIR != GIT_COMMON` is also true inside git submodules. Before concluding "already in a worktree," verify you are not in a submodule:
```bash
# If this returns a path, you're in a submodule, not a worktree — treat as normal repo
git rev-parse --show-superproject-working-tree 2>/dev/null
```

The line at the top of this page pins the label git:20260822.9d40859, 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.
