# worktree-pr

This skill runs larger or riskier tasks in a separate git worktree, checks the result against the untouched copy, and prepares a branch for a pull request.

## What it does

worktree-pr helps decide whether a task needs its own working copy. When it does, the skill starts a branch from the current integration branch, leaves the main checkout alone, and compares the result with the original state. That separation suits parallel tasks and changes that need review before they land.

Fetch the base branch first. Parallel worktrees should touch different files; otherwise, the conflict surfaces when the changes come together. Save screenshots, builds, and exports somewhere durable or attach them to the PR, since removing a worktree also removes its local artifacts.

Before calling the task done, compare old and new behavior and account for generated changes such as lock-file updates. The skill prepares a pull request but leaves merging to the repository owner unless asked otherwise. If pushing or opening a PR needs explicit approval, the agent hands over the commands for authorization first.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add scarletkc/agents --skill worktree-pr -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/worktree-pr/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/worktree-pr/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add scarletkc/agents --skill worktree-pr -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/worktree-pr/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add scarletkc/agents --skill worktree-pr -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/worktree-pr/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install scarletkc/agents worktree-pr
```

2. **Manually: put the files in place**
- File: `.github/skills/worktree-pr/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add scarletkc/agents --skill worktree-pr -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/scarletkc/agents --path skills/worktree-pr
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/worktree-pr/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add scarletkc/agents --skill worktree-pr -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/scarletkc/agents/tree/HEAD/skills/worktree-pr/SKILL.md

## When to use it
- isolate a risky change from the main checkout
- run parallel tasks in one repository
- compare changed behavior with the original
- prepare a branch for a pull request without merging
- keep worktree artifacts somewhere durable

## Example prompts
- Run this larger task in a separate git worktree and leave the main checkout untouched.
- Make a separate branch for this risky change, then compare it with the original behavior.
- Prepare the worktree changes for a pull request and report what remains unverified.

description: "Decide whether a task deserves its own git worktree and, if chosen, run it end to end: branch from the integration branch rather than the current tree, keep the main working copy untouched while the task runs, compare the result against the untouched baseline before declaring it done, and prepare it for a pull request instead of merging. Use when a request says to do the work in a new worktree or branch, when a change is large or risky enough that the main tree should stay usable, when several tasks need to run in parallel on one repository, when a result has to be diffed against current behavior, and when deciding where screenshots, builds, and other artifacts produced in a worktree should end up."

# Worktree & PR

A worktree buys two things: the main working copy stays usable while the task
runs, and the untouched copy remains available as a baseline to compare
against. Both are worth real setup cost, and neither applies to every change.

This covers the isolation mechanics. How large the change itself should be is
[`scoped-change`](https://github.com/scarletkc/agents/blob/main/skills/scoped-change/SKILL.md),
and it applies inside a worktree exactly as it does anywhere else.

## Deciding

Consider a worktree when at least one holds: the task is large enough that a
half-finished state would block other work, several tasks need to progress on
the same repository at once, the result has to be compared against current
behavior, or the change is risky enough that abandoning it should cost
nothing.

Skip it when the change is small, self-contained, and reviewable in one pass.
Setting up an isolated copy for a typo fix or a one-line config edit costs
more than it saves, and the extra branch, directory, and PR are all overhead
that someone pays later. When the requester says to work directly on the
current branch, that decision is already made.

## Running

- **Branch from the integration branch, not from whatever is checked out.**
  The point of the isolated copy is a clean starting state; inheriting
  unrelated in-progress edits forfeits it and makes the eventual diff
  unreadable. Fetch first so the base is current, not a stale local ref.
- **Leave the main working copy alone while the task runs.** Editing both
  defeats the isolation and destroys the baseline. If the task turns out to
  need a change in the main tree, stop and say so rather than reaching
  across.
- **Parallel worktrees stay independent only while they stay disjoint.** Two
  copies of one repository editing the same files converge into a conflict
