name: create-worktree-skill description: Use when the user explicitly asks for a SKILL to create a worktree. If the user does not mention "skill" or explicitly request skill invocation, do NOT trigger this. Only use when user says things like "use a skill to create a worktree" or "invoke the worktree skill". Creates isolated git worktrees with parallel-running configuration. allowed-tools: SlashCommand, Bash, Read, Write, Edit, Glob, Grep

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:

/git-simple:create_worktree_prompt <branch-name> [port-offset]

Examples:

• /git-simple:create_worktree_prompt feature-auth - Creates worktree with auto-calculated ports
• /git-simple:create_worktree_prompt fix-bug 2 - Creates worktree with port offset 2 (ports 4020, 5193)

Step 3: Share results

The /git-simple: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 /git-simple: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 /git-simple: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:

1. Use SlashCommand to run /git-simple:create_worktree_prompt feature-a
2. Use SlashCommand to run /git-simple:create_worktree_prompt feature-b
3. Use SlashCommand to run /git-simple: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.
