description: Use when checking out a PR, branch, or ref for local work - sets up worktree with context

Git Checkout

Overview

Check out a PR, branch, or ref into an isolated worktree with relevant context.

Announce: "Using git:checkout to set up a worktree for {target}..."

When to Use

  • User wants to review a PR locally
  • User wants to work on a specific branch in isolation
  • User provides PR URL/number or branch name
  • Following git:inbox when user picks a PR

Input Formats

Accept:

  • Full PR URL: https://github.com/{owner}/{repo}/pull/{number}
  • Short PR: {repo}#{number} or #{number} (infer repo from cwd)
  • PR number only: {number} (infer owner/repo from git remote)
  • Branch name: feature/auth, main, etc.
  • Ref: commit SHA, tag

Workflow

For PRs

1. Parse PR Reference

bash
# Get owner/repo from current directory if needed
gh repo view --json owner,name -q '"\(.owner.login)/\(.name)"'

2. Fetch PR Details

bash
gh pr view {number} --json title,body,author,state,baseRefName,headRefName,url,reviews,reviewRequests

3. Set Up Worktree

REQUIRED: Use superpowers:using-git-worktrees skill for directory selection.

bash
# Fetch the PR branch
git fetch origin {headRefName}

# Create worktree
git worktree add .worktrees/pr-{number}-{short-desc} origin/{headRefName}

Naming: pr-{number}-{2-3-word-description} (e.g., pr-1234-add-oauth)

4. Present Context

markdown
## PR #{number} Ready for Review

**Title:** {title}
**Author:** @{author}
**Branch:** {headRefName} → {baseRefName}
**URL:** {full_url}

### Summary
{1-3 sentence summary from PR body}

### Files Changed ({count})
{Grouped by directory}

### Review Status

**Worktree ready at:** `{full_path}`

For Branches

bash
# For existing branch
git worktree add .worktrees/{branch-slug} {branch}

# For new branch
git worktree add .worktrees/{branch-slug} -b {branch}

2. Report Ready

markdown
**Worktree ready at:** `{full_path}`
**Branch:** {branch}
