Checkout PR to Worktree

You are checking out a pull request into an isolated git worktree so the user can review or test it.

Input

The user provides a PR number, #number, or a full GitHub PR URL as the argument.

Steps

1. Parse the PR identifier from the argument. Extract just the number.

2. Fetch PR metadata using mcp__github__pull_request_read with the repo umbraco/Umbraco.AI and the PR number. Note the:

   • Branch name (headRefName)
   • Title
   • Author
   • Base branch

3. Fetch the latest from origin so the branch is available locally:

   git fetch origin <branch-name>
   

4. Enter the worktree using EnterWorktree with name set to the PR's branch name (e.g., feature/add-streaming). The branch name contains a /, so the worktree hook will treat it as an explicit branch and track the remote.

5. Show a summary to the user:

   • PR title and number
   • Author
   • Branch name
   • Base branch
   • A note that they're now in an isolated worktree

Important

• The worktree hook handles the / convention: branch names with / are used as-is (no feature/ prefix added).
• If the PR branch doesn't exist on origin, report the error clearly.
• Do NOT modify any files or make commits. This is a read-only checkout for review.
