Git Worktree Management

Manage git worktrees for parallel branch development. Each operation runs standard git commands.

Arguments: $ARGUMENTS

• First argument is the operation. Second argument is the branch name (required for create, merge, rebase, remove).
• If $ARGUMENTS is empty, default to list.

Path Calculation

All operations derive paths from git:

REPO_ROOT=$(git rev-parse --show-toplevel)
PARENT_DIR=$(dirname "$REPO_ROOT")
WORKTREE_DIR="$PARENT_DIR/$BRANCH_NAME"

Operations

create

Create a new worktree as a sibling directory with a new branch.

REPO_ROOT=$(git rev-parse --show-toplevel)
git worktree add "$(dirname "$REPO_ROOT")/<branch>" -b <branch>

After creation, remind the user:

• Run /worktree-secrets in the new worktree to copy .envrc and GPG keys
• Open a new terminal in the worktree directory

list

Show all worktrees.

git worktree list

merge

Merge the current worktree's branch into main. Run from the feature worktree.

Pre-check: Verify the current branch is NOT main. If on main, refuse — there's nothing to merge.

REPO_ROOT=$(git rev-parse --show-toplevel)
BRANCH=$(git rev-parse --abbrev-ref HEAD)
MAIN_DIR="$(dirname "$REPO_ROOT")/main"

git -C "$MAIN_DIR" fetch origin && git -C "$MAIN_DIR" pull
git -C "$MAIN_DIR" merge "$BRANCH"
git -C "$MAIN_DIR" push origin main

If there are conflicts, help the user resolve them before pushing.

rebase

Rebase a branch onto the latest main. Must be run from within the branch's worktree.

Pre-check: Verify the current branch matches <branch>. If not, refuse and instruct the user to switch to the correct worktree.

git fetch origin
git rebase origin/main

If there are conflicts, help the user resolve them. After successful rebase, remind the user that force-push is required if the branch was previously pushed (but only with explicit permission per safety rules).

remove

Remove a worktree and delete its branch. Must be run from the main worktree.

Pre-checks:

1. Verify the current worktree is the main branch. If not, refuse.
2. Verify the branch is merged into main using git branch --merged. If not merged, refuse and instruct the user to merge first.

git worktree remove "$(dirname "$REPO_ROOT")/<branch>"
git branch -d <branch>

If git branch -d fails with "not fully merged", stop and tell the user to merge first. Never use git branch -D.

Safety Rules

• Local merges only. Do not create pull requests.
• If the worktree has unstaged or uncommited work during remove operation, ask the user about merging or forcing delete
• Never delete a worktree branch manually. Only use git worktree remove
• Never delete a worktree directory manually. Always use git worktree remove.
• Never force push without explicit user permission.
• Derive paths from git rev-parse --show-toplevel and dirname. Never hardcode paths.
