worktree-task

This skill manages large coding tasks by spawning autonomous agent instances (默认 Claude Code，可选 --codex/--agent-cmd) in separate git worktrees via tmux sessions.

When to Use

• User wants to execute a large task (>20 subtasks) without blocking current session
• User mentions "background", "parallel", "worktree", or "autonomous" execution
• Task involves creating a new service, major refactoring, or implementing complex features
• User wants to continue other work while a large task runs

Available Commands

Use these slash commands for precise control:

| Command | Description | |---------|-------------| | /worktree:launch | Launch a new background task | | /worktree:status | Check status of all or specific tasks | | /worktree:resume | Resume an interrupted task | | /worktree:cleanup | Clean up completed tasks |

Core Workflow

1. Launch a Task

python3 ${CLAUDE_PLUGIN_ROOT}/scripts/launch.py <branch-name> "<task-description>"

Example:

python3 ${CLAUDE_PLUGIN_ROOT}/scripts/launch.py feature/my-task "Execute the task: implement new feature. Read the tasks.md and implement all phases."

The script will:

1. Verify git status is clean (or prompt to commit/stash)
2. Create a git worktree with the specified branch
3. Create a tmux session
4. Launch Claude Code by default (use --codex for default Codex command or --agent-cmd to switch, e.g., codex --yolo -m gpt-5.1-codex-max -c model_reasoning_effort="high")
5. Send the task with instructions to use Task tool for each phase

2. Monitor Progress

python3 ${CLAUDE_PLUGIN_ROOT}/scripts/status.py [session-name]

Without arguments, lists all active sessions. With a session name, shows detailed status.

3. Resume an Interrupted Task

If a task is interrupted (rate limit, API error, timeout):

python3 ${CLAUDE_PLUGIN_ROOT}/scripts/resume.py <session-name> [message]

Options:

• --retry - Retry the last failed task
• --check - Only check status, don't send message

4. Cleanup

python3 ${CLAUDE_PLUGIN_ROOT}/scripts/cleanup.py <session-name> [--remove-worktree]

Alerts

This plugin automatically sends macOS notifications when:

• A background task completes successfully
• A task encounters an error (rate limit, API error)
• A session ends

Configure alerts in hooks/hooks.json.

Critical Instructions for Spawned Claude

The spawned agent receives these critical instructions:

1. MUST use Task tool - Each major phase must be executed via Task tool to prevent context overflow
2. Silent mode - No confirmations needed, user has pre-approved all operations
3. Complete execution - Do not stop until all tasks are done
4. Track with TodoWrite - Create and update todo list for visibility
5. Commit often - Make atomic commits after each logical unit

Notes

• Worktrees are created in parent directory: ../<project>-<branch-name>
• tmux session names have / and . replaced with -
• Use tmux attach -t <session> to take over interactively
• The spawned Claude runs with full permissions (--dangerously-skip-permissions)
