Workflow

For PRs

gh repo view --json owner,name -q '"\(.owner.login)/\(.name)"'

2. Fetch PR Details

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.

# 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)
