Worktree Creator Skill
This skill enables creating fully configured git worktrees for parallel development with isolated ports, databases, and configuration.
When to use this skill
Use this skill when:
- User asks to create a git worktree
- User wants to set up parallel development environments
- User needs to run multiple instances simultaneously
- User mentions working on multiple branches at once
- User wants isolated testing environments
Instructions
Step 1: Understand the request
Extract from the user’s request:
- Branch name (required): The git branch to create the worktree from
- If the branch name is not provided, stop and ask the user to provide a branch name
- Port offset (optional): Custom port offset (if not provided, auto-calculated)
Step 2: Invoke the slash command
Use the SlashCommand tool to run:
/create_worktree_prompt <branch-name> [port-offset]Examples:
/create_worktree_prompt feature-auth- Creates worktree with auto-calculated ports/create_worktree_prompt fix-bug 2- Creates worktree with port offset 2 (ports 4020, 5193)
Step 3: Share results
The /create_worktree_prompt command will:
- Create the git worktree in
trees/<branch-name> - Configure isolated ports (auto-incremented to avoid conflicts)
- Set up environment files with proper configuration
- Install dependencies for server and client
- Start both services automatically
- Provide access URLs and management instructions
Share the command output with the user, highlighting:
- Access URLs for the dashboard
- Ports being used
- How to stop/restart the worktree
- How to remove it later
Examples
Example 1: Simple worktree creation
User: “Create a worktree for the feature-dashboard branch”
Your response: Use SlashCommand to run /create_worktree_prompt feature-dashboard
Example 2: Worktree with specific port offset
User: “Set up a parallel environment on branch hotfix-security with port offset 5”
Your response: Use SlashCommand to run /create_worktree_prompt hotfix-security 5
Example 3: Multiple worktrees
User: “I need worktrees for branches: feature-a, feature-b, and feature-c”
Your response:
- Use SlashCommand to run
/create_worktree_prompt feature-a - Use SlashCommand to run
/create_worktree_prompt feature-b - Use SlashCommand to run
/create_worktree_prompt feature-c
Each will automatically get unique ports (4010/5183, 4020/5193, 4030/5203).
Related capabilities
- The created worktree will run automatically with isolated ports, database, and configuration
- Each worktree is completely independent and can run simultaneously with others
Troubleshooting
If the command fails, common issues:
- Branch name already exists as a worktree
- Ports are in use (command kills them automatically)
- Missing dependencies (ensure bun is installed)
- Git worktree errors (handle uncommitted changes first)
The slash command provides detailed error messages and suggestions.
