/create_worktree

Configuration Note

This command uses ticket references like PROJ-123. Replace PROJ with your Linear team's ticket prefix:

• Read from .claude/config.json if available
• Otherwise use a generic format like TICKET-XXX
• Examples: ENG-123, FEAT-456, BUG-789

You are tasked with creating a git worktree for parallel development work.

Process

When this command is invoked:

1. Gather required information:

   • Worktree name (e.g., PROJ-123, feature-name)
   • Base branch (default: current branch)
   • Optional: Path to implementation plan

2. Confirm with user: Present the worktree details and get confirmation before creating.

3. Create the worktree: Use the create-worktree.sh script:

   "${CLAUDE_PLUGIN_ROOT}/scripts/create-worktree.sh" <worktree_name> [base_branch]
   

   The script automatically:

   • Detects GitHub org/repo from git remote
   • Uses GITHUB_SOURCE_ROOT environment variable if set
   • Creates worktrees in a clean, organized structure

4. Initialize thoughts (REQUIRED - handled automatically by script):

   The create-worktree.sh script automatically initializes thoughts and syncs with the shared repository, giving the worktree access to:

   • Shared research documents
   • Implementation plans
   • Handoff documents
   • Team knowledge base

5. Optional: Launch implementation session: If a plan file path was provided, ask if the user wants to launch Claude in the worktree:

   humanlayer launch --model opus -w <worktree_path> \
     "/implement_plan <plan_path> and when done: create commit, create PR, update Linear ticket"
   

Worktree Location Convention

Recommended Setup: Set GITHUB_SOURCE_ROOT environment variable for clean organization:

# In ~/.zshrc or ~/.bashrc
export GITHUB_SOURCE_ROOT="$HOME/code-repos/github"

Convention:

• Main repository: ${GITHUB_SOURCE_ROOT}/<org>/<repo>
  • Example: ~/code-repos/github/coalesce-labs/catalyst
• Worktrees: ${GITHUB_SOURCE_ROOT}/<org>/<repo>-worktrees/<feature>
  • Example: ~/code-repos/github/coalesce-labs/catalyst-worktrees/PROJ-123

Fallback behavior (if GITHUB_SOURCE_ROOT not set):

• Defaults to ~/wt/<repo_name>/<worktree_name>

Why this convention?

• ✅ Main branches and worktrees are organized together by org/repo
• ✅ Easy to find: all worktrees for a project in one place
• ✅ Clean separation: <repo> vs <repo>-worktrees
• ✅ Configurable per-developer via environment variable
• ✅ No hardcoded paths in scripts or documentation

Example with GITHUB_SOURCE_ROOT:

~/code-repos/github/
├── coalesce-labs/
│   ├── catalyst/                    # Main branch
│   └── catalyst-worktrees/          # All worktrees
│       ├── PROJ-123-feature/
│       └── PROJ-456-bugfix/
└── acme/
    ├── api/                          # Main branch
    └── api-worktrees/                # All worktrees
        └── ENG-789-oauth/
