Aio Worktree

Git Worktree Management

Manages git worktrees for parallel development workflows.

Environment

• git: !which git 2>/dev/null || echo "NOT INSTALLED"
• Scripts: !echo "${CLAUDE_PLUGIN_ROOT}/skills/aio-worktree"

Scripts Path

WT="${CLAUDE_PLUGIN_ROOT}/skills/aio-worktree"

Set this in every shell block that calls a script. Then reference scripts as $WT/script-name.

Available Scripts

Workflow

1. Create Worktree

WT="${CLAUDE_PLUGIN_ROOT}/skills/aio-worktree"
$WT/worktree-create.sh <name> [source_ref]

# Examples:
$WT/worktree-create.sh feature-login          # from HEAD
$WT/worktree-create.sh hotfix-bug main        # from main branch
$WT/worktree-create.sh experiment abc123      # from specific commit

# Creates:
#   Folder: {repo}--wtr-{name}  (e.g., myrepo--wtr-feature-login)
#   Branch: wtr-{name}          (e.g., wtr-feature-login)

2. Sync (Rebase + Fast-Forward)

Sync worktree with parent branch. Both end up at the same commit with same hash.

# From within worktree directory
$WT/worktree-sync.sh

How it works:

1. Rebase worktree onto parent (get latest from main, put your commits on top)
2. Fast-forward parent to worktree (now both identical)

Result: Both branches at same commit, same hash. No duplicates.

Example workflow:

# In worktree: make changes, commit
git add . && git commit -m "feat: new feature"

# Sync with main
$WT/worktree-sync.sh

# Output:
# Syncing: wtr-feature ↔ main
# Status: worktree +2 commits, parent +1 commits
# === Step 1: Rebase onto main ===
# === Step 2: Fast-forward main ===
# Sync complete!
# Both branches at: abc1234

3. Spotlight (Temporary File Sync)

Preview worktree changes in main repo with hot reload. One-way sync, temporary.

# Run in background from MAIN repo
$WT/worktree-spotlight.sh <worktree_path> . [excludes...]

# Example:
$WT/worktree-spotlight.sh ../myrepo--wtr-feature . node_modules dist .env

How it works:

• Watches worktree for file changes
• Copies changed files to main repo (for hot reload preview)
• On exit: main repo restored to clean state
• Does NOT commit anything - purely temporary

Important:

• Run with run_in_background: true
• Main repo must be clean before starting

To stop: Ctrl+C or kill <PID>. Cleanup is automatic.

4. Remove Worktree

WT="${CLAUDE_PLUGIN_ROOT}/skills/aio-worktree"
$WT/worktree-remove.sh <path_or_name>

# Examples:
$WT/worktree-remove.sh ../myrepo--wtr-feature  # by path
$WT/worktree-remove.sh feature                 # by name (auto-resolves path)

Common Scenarios

"Multiple AI agents working in parallel"

WT="${CLAUDE_PLUGIN_ROOT}/skills/aio-worktree"

# Agent A creates worktree
$WT/worktree-create.sh agent-a-task

# Agent B creates worktree
$WT/worktree-create.sh agent-b-task

# Both work and commit independently...

# Agent A syncs first
cd ../repo--wtr-agent-a-task
$WT/worktree-sync.sh
# main now has Agent A's commits

# Agent B syncs (gets A's work + pushes B's work)
cd ../repo--wtr-agent-b-task
$WT/worktree-sync.sh
# main now has both A and B's commits
# Agent B's worktree also has A's commits

# Agent A syncs again to get B's work
cd ../repo--wtr-agent-a-task
$WT/worktree-sync.sh
# All three (main, worktree-a, worktree-b) now identical

"I want hot reload preview while working in worktree"

1. Ensure main repo is clean
2. Run spotlight: worktree-spotlight.sh <worktree> . node_modules
3. Edit in worktree → changes appear in main for hot reload
4. Stop spotlight → main restored clean
5. Commit in worktree, then sync: worktree-sync.sh

"I want to work on a feature and sync with main"

1. Create worktree: worktree-create.sh feature-x
2. Work in worktree, commit as usual
3. Sync anytime: worktree-sync.sh
4. When done: worktree-remove.sh feature-x

Error Recovery

"Spotlight crashed"

WT="${CLAUDE_PLUGIN_ROOT}/skills/aio-worktree"
$WT/worktree-cleanup.sh .

"Sync has conflicts"

Script will stop at rebase conflict. Resolve conflicts, then:

git rebase --continue
# Then run sync again
$WT/worktree-sync.sh

Worktrees + Agent Teams

When using Agent Teams (experimental, requires CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1), combine worktrees with agent teams for maximum parallel safety.

Pattern: Each teammate gets their own worktree

WT="${CLAUDE_PLUGIN_ROOT}/skills/aio-worktree"

# Lead creates worktrees for each teammate
$WT/worktree-create.sh teammate-frontend
$WT/worktree-create.sh teammate-backend
$WT/worktree-create.sh teammate-tests

# Each teammate works in their own worktree (no file conflicts)
# Teammate messages via SendMessage when ready to sync
# Lead coordinates sync order to avoid conflicts

Why: Agent teams let multiple Claude instances work in parallel. Worktrees give each instance an isolated filesystem. Combined = true parallel development without merge conflicts.

Sync strategy with teams:

1. Teammates work and commit independently in their worktrees
2. When a teammate finishes, they message the lead
3. Lead runs worktree-sync.sh in order (first-done-first-synced)
4. Later teammates get earlier teammates' work when they sync
5. All worktrees converge to the same history

When NOT to combine: If tasks are small and touch different files anyway, agent teams alone (without worktrees) work fine. Use worktrees when there's ANY risk of file overlap.

Key Points

• Naming convention: wtr- prefix for easy identification
  • Folder: {repo}--wtr-{name} (e.g., myrepo--wtr-feature)
  • Branch: wtr-{name} (e.g., wtr-feature)
• Sync keeps same hash: Rebase + fast-forward = identical commits
• No duplicate commits: Unlike cherry-pick, sync keeps history clean
• Parallel-friendly: Multiple worktrees can sync independently
• Spotlight = file-based: Temporary file copying for preview, no commits
• Always commit before sync: Sync works with commits, not uncommitted changes
• Spotlight fallback: Uses polling if fswatch not installed (brew install fswatch)
