Using Git Worktrees
Overview
VAULT — A vault is a sealed, isolated chamber — what happens inside cannot contaminate what's outside.
When invoked: creates an isolated git worktree so implementation work is completely separated from the main branch — parallel agents cannot corrupt each other's state, and breaking changes stay contained until verified.
Core principle: Systematic directory selection + safety verification = reliable isolation.
Announce at start: "Running VAULT to set up an isolated workspace."
Directory Selection Process
Follow this priority order:
1. Check Existing Directories
ls -d .worktrees 2>/dev/null
ls -d worktrees 2>/dev/null
If found: use that directory. If both exist, .worktrees/ wins.
2. Check CLAUDE.md
grep -i "worktree.*director" CLAUDE.md 2>/dev/null
If a preference is specified: use it without asking.
3. Ask the User
If no directory exists and no CLAUDE.md preference:
No worktree directory found. Where should I create worktrees?
1. .worktrees/ (project-local, hidden)
2. ~/.config/superpowers/worktrees/<project-name>/ (global)
Which would you prefer?
Safety Verification
For Project-Local Directories (.worktrees/ or worktrees/)
MUST verify the directory is gitignored before creating the worktree:
git check-ignore -q .worktrees 2>/dev/null || git check-ignore -q worktrees 2>/dev/null
If NOT ignored — fix immediately:
- Add the line to
.gitignore
- Commit the change
- Then proceed with worktree creation
Why critical: Prevents accidentally committing worktree contents to the repository.
For Global Directory (~/.config/superpowers/worktrees/)
No .gitignore verification needed — it's outside the project entirely.
Creation Steps
1. Detect Project Name
project=$(basename "$(git rev-parse --show-toplevel)")
2. Create the Worktree
git worktree add "$path" -b "$BRANCH_NAME"
cd "$path"
3. Run Project Setup (auto-detect)
if [ -f package.json ]; then npm install; fi
if [ -f Cargo.toml ]; then cargo build; fi
if [ -f requirements.txt ]; then pip install -r requirements.txt; fi
if [ -f pyproject.toml ]; then poetry install; fi
if [ -f go.mod ]; then go mod download; fi
4. Verify Clean Baseline
npm test / cargo test / pytest / go test ./...
- Tests fail → report failures, ask whether to proceed or investigate
- Tests pass → report ready
5. Report Location
Worktree ready at <full-path>
Tests passing (<N> tests, 0 failures)
Ready to implement <feature-name>
Quick Reference
| 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 gitignored | Add to .gitignore + commit first |
| Tests fail at baseline | Report failures + ask before proceeding |
| No package.json / Cargo.toml | Skip dependency install |
Red Flags
Never:
- Create a project-local worktree without verifying it is gitignored
- Skip baseline test verification
- Proceed with failing tests without asking
- Assume directory location when ambiguous
- Skip the CLAUDE.md check
Always:
- Priority order: existing directory > CLAUDE.md preference > ask user
- Verify gitignore for project-local directories
- Auto-detect and run project setup
- Confirm clean test baseline before handing off
Integration
Called by:
architect — required when design is approved and implementation follows
phantom — required before executing any plan tasks
exodus — required before executing any plan tasks
Pairs with:
seal — cleans up the worktree after work is complete
