Vault

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

bashCopy code
ls -d .worktrees 2>/dev/null     # Preferred (hidden)
ls -d worktrees 2>/dev/null      # Alternative

If found: use that directory. If both exist, .worktrees/ wins.

2. Check CLAUDE.md

bashCopy code
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:

Copy code
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:

bashCopy code
git check-ignore -q .worktrees 2>/dev/null || git check-ignore -q worktrees 2>/dev/null

If NOT ignored — fix immediately:

1. Add the line to .gitignore
2. Commit the change
3. 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

bashCopy code
project=$(basename "$(git rev-parse --show-toplevel)")

2. Create the Worktree

bashCopy code
git worktree add "$path" -b "$BRANCH_NAME"
cd "$path"

3. Run Project Setup (auto-detect)

bashCopy code
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

bashCopy code
# Use the project's test command
npm test / cargo test / pytest / go test ./...

• Tests fail → report failures, ask whether to proceed or investigate
• Tests pass → report ready

5. Report Location

Copy code
Worktree ready at <full-path>
Tests passing (<N> tests, 0 failures)
Ready to implement <feature-name>

Quick Reference

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
