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.
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:
git rev-parse --show-superproject-working-tree 2>/dev/null
If GIT_DIR != GIT_COMMON (and not a submodule): You are already in a linked worktree. Skip to Step 2 (Project Setup). Do NOT create another worktree.
Report with branch state:
- On a branch: "Already in isolated workspace at
<path> on branch <name>."
- Detached HEAD: "Already in isolated workspace at
<path> (detached HEAD, externally managed). Branch creation needed at finish time."
If GIT_DIR == GIT_COMMON (or in a submodule): You are in a normal repo checkout.
Has the user already indicated their worktree preference in your instructions? If not, ask for consent before creating a worktree:
"Would you like me to set up an isolated worktree? It protects your current branch from changes."
Honor any existing declared preference without asking. If the user declines consent, work in place and skip to Step 2.
Step 1: Create Isolated Workspace
You have two mechanisms. Try them in this order.
