Safe Editing

Use Git worktree to isolate AI-driven changes from the main working directory.

Trigger Conditions

Activate this skill when:

• AI is about to make its first code modification in the current session
• User explicitly requests safe/isolated editing
• Starting a new feature implementation or bug fix

Workflow

1. Check Current State

git rev-parse --show-toplevel
git worktree list
git status --porcelain

Verify:

• In a Git repository
• No uncommitted changes in main directory
• Not already in a worktree

If uncommitted changes exist, ask user how to proceed (stash, commit, or abort).

2. Determine Branch Name

Analyze the task and generate a branch name:

• Use lowercase kebab-case
• Translate Japanese to English
• Keep concise but descriptive

3. Create Worktree

Use the gwt alias (defined in .zshrc):

gwt <branch-name>

This creates:

• New branch: <branch-name>
• Worktree at: ../git-worktrees/<repo-name>-<branch-name>

4. Navigate to Worktree

cd ../git-worktrees/<repo-name>-<branch-name>

Confirm the switch:

pwd
git branch --show-current

5. Perform Changes

Execute the requested modifications in the worktree directory. All file edits, creations, and deletions happen here.

6. Commit, Push, and Create PR

Use the commit-push-pr skill to:

1. Stage and commit changes
2. Push to remote
3. Create pull request

7. Cleanup (After PR Merge)

Once the PR is merged, clean up the worktree:

cd <original-repo-path>
gwtr ../git-worktrees/<repo-name>-<branch-name>

Quick Reference

Notes

• Always confirm with user before creating worktree
• If worktree already exists for the task, reuse it
• Keep main directory clean for other work
