Automated summary
Creates isolated git worktrees with dedicated ports for parallel development.
Strengths
- Automatic unique port allocation to avoid conflicts
- Completely isolated development environments
- Simplified dev server management (start, stop, restart)
- Easy worktree removal via provided instructions
Limitations
- Only works with Next.js projects
- Requires the git repository to be already set up
- May fail if the port is already in use (requires manual offset)
Use this skill when you need to work on multiple branches simultaneously with isolated dev servers.
Do not use it if a simple branch switch suffices or if the project is not Next.js-based.
Security analysis
SafeThe skill uses a slash command to create git worktrees for development. It does not contain any destructive actions, data exfiltration, or code obfuscation. The allowed tools are used for legitimate environment setup.

Worktree Creator Skill
This skill enables creating fully configured git worktrees for parallel development with isolated ports and configuration. Each worktree gets its own Next.js dev server instance on a unique port.
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 port/create_worktree_prompt fix-bug 2- Creates worktree with port offset 2 (port 9655)
Step 3: Share results
The /create_worktree_prompt command will:
- Create the git worktree in
trees/<branch-name> - Configure an isolated port (9653 + offset)
- Copy environment files from main project
- Install npm dependencies
- Start the dev server automatically using the dev-server script
- Provide access URL and management instructions
Share the command output with the user, highlighting:
- Access URL for the app
- Port being used
- How to manage the dev server (start/stop/restart/status/logs)
- How to remove the worktree 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 3"
Your response: Use SlashCommand to run /create_worktree_prompt hotfix-security 3
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 (9654, 9655, 9656).
Troubleshooting
If the command fails, common issues:
- Branch name already exists as a worktree
- Port is in use (try a different offset)
- Missing dependencies (ensure npm/node is installed)
- Git worktree errors (handle uncommitted changes first)
From the file to a first result
The download contains exactly the content displayed on this page. This copy may differ from the latest version in the source repository.
View the source and supporting filesThis download contains SKILL.md only. Any scripts, references, templates and dependencies are not included. Get the required files from the source, preserving their directory structure, before continuing.
1. Download the file
Download SKILL.mdFrom the root of a test project, save the file as .skill-downloads/git-worktree-creator-mmbizkr4/SKILL.md, or use the command below. This folder is for inspecting the skill before installation.
Command for macOS/Linux or WSL: requires a POSIX shell and curl. On Windows without WSL, use the download button and create the folder manually.
mkdir -p '.skill-downloads/git-worktree-creator-mmbizkr4' && curl --fail --show-error --location 'https://skills-guides.com/api/skills/git-worktree-creator-mmbizkr4/download' --output '.skill-downloads/git-worktree-creator-mmbizkr4/SKILL.md.part' && mv '.skill-downloads/git-worktree-creator-mmbizkr4/SKILL.md.part' '.skill-downloads/git-worktree-creator-mmbizkr4/SKILL.md'2. Check prerequisites
Read SKILL.md before using it. If it references scripts or external services, inspect them and prepare the required access in your test environment.

No recognized prerequisites section in this file. This does not mean it is self-contained: libraries, tools and access requirements may be mentioned elsewhere in the content or source repository.
The platforms on this page are catalog indications. The paths below follow tool documentation; they do not prove this skill has been run in those tools. No minimum tool version is confirmed for this listing.
3. Load the skill
After inspection, copy the complete folder into your project using one of the commands below, then open a new tool session. The command stops if a folder with the same name already exists: compare the files before replacing it.

For an agent that reads AGENTS.md, then sync the index. This command changes AGENTS.md: review the diff before using it.

4. Try a first task
Use a short, synthetic input: an API endpoint, a small document or an interface brief. In a new conversation, attach the file or give the agent its path, then adapt this request:
Read .skill-downloads/git-worktree-creator-mmbizkr4/SKILL.md and apply its instructions to this example: [describe a test input]. Identify any missing files, dependencies or access. Produce the result requested by the skill without inventing data or running unreviewed scripts.Expected result: output matching the skill instructions, or a precise list of missing prerequisites. A read confirmation alone does not validate a first use. If an external resource is unavailable, that path remains untested.

Development
Analyzes git diffs against a stated intent to detect scope creep, unrelated files, broad PRs, and oversized changes, then suggests keep, split, or justify actions.
