What jackin-checkout-pr does

The skill accepts a pull request number, URL, or branch name. Numbers and URLs go straight to gh pr checkout; a branch is resolved with gh pr list --head <branch> --state all --json number -q '.[0].number'. If no PR matches, it stops instead of falling back to raw git checkout.

Before changing branches, it runs git status --porcelain and records the current branch. A dirty worktree stops the process and requires the operator to commit, stash, or discard the changes; the skill never stashes automatically. It checks the PR state, asks for confirmation on merged or closed requests, verifies the resulting branch, and reports git switch <old> as the way back.

What it helps with

move a repository to a pull request branch
resolve a PR from its head branch
block checkout when local changes exist
check whether a PR is still open
show how to return to the previous branch

Example prompts for the agent

Explicitly use jackin-checkout-pr to switch to pull request 123.
Use jackin-checkout-pr to reach the pull request for branch feature/login.
Run jackin-checkout-pr with the pull request URL and check the worktree first.

# jackin-checkout-pr

Switch the working repo onto a PR's branch via `gh pr checkout`. Accepts a number, URL, or branch name.

## Process

1. **Resolve to a PR number.** Number or URL → pass to `gh pr checkout` directly. Branch name → `gh pr list --head <branch> --state all --json number -q '.[0].number'`; no match → STOP, do not fall back to raw `git checkout`.

2. **Guard the working tree.** `git status --porcelain` — if dirty, STOP and ask the operator to commit, stash, or discard first. Never auto-stash. Note `git branch --show-current` (the way back).

3. **Check the PR is open.** `gh pr view <N> --json state,headRefName`. `MERGED` or `CLOSED` → warn (the branch may be stale) and confirm before proceeding.

4. **Switch.** `gh pr checkout <N>`. Verify `git branch --show-current` matches `headRefName`.

5. **Report.** Switched from `<old>` to `<headRefName>` (PR #N). Way back: `git switch <old>`.
