npx skills add davila7/claude-code-templates --skill using-git-worktrees
Use when starting feature work that needs isolation from current workspace or before executing implementation plans - creates isolated git worktrees with smart directory selection and safety verification
npx skills add davila7/claude-code-templates --skill using-git-worktrees
Git worktrees create isolated workspaces sharing the same repository, allowing work on multiple branches simultaneously without switching.
Core principle: Systematic directory selection + safety verification = reliable isolation.
Announce at start: "I'm using the using-git-worktrees skill to set up an isolated workspace."
Follow this priority order:
If found: Use that directory. If both exist, .worktrees wins.
If preference specified: Use it without asking.
If no directory exists and no CLAUDE.md preference:
MUST verify directory is ignored before creating worktree:
If NOT ignored:
Per Jesse's rule "Fix broken things immediately":
Why critical: Prevents accidentally committing worktree contents to repository.
No .gitignore verification needed - outside project entirely.
Auto-detect and run appropriate setup:
Run tests to ensure worktree starts clean:
If tests fail: Report failures, ask whether to proceed or investigate.
If tests pass: Report ready.
| Situation | Action |
|---|---|
.worktrees/ exists | Use it (verify ignored) |
worktrees/ exists | Use it (verify ignored) |
| Both exist | Use .worktrees/ |
| Neither exists | Check CLAUDE.md → Ask user |
| Directory not ignored | Add to .gitignore + commit |
| Tests fail during baseline | Report failures + ask |
| No package.json/Cargo.toml | Skip dependency install |
