description: Open a pull request on pascalorg/editor using the repo's PR template. Use when the user asks to open/create a PR, push and PR, or ship a branch in the editor repo.

Open a pull request against `pascalorg/editor` from the current branch.

## 1. Pre-flight

```bash
git status                # confirm working tree state
git branch --show-current # confirm we're on a feature branch, not main
git log --oneline main..HEAD
```

Stop if:
- The current branch is `main`. Ask the user to create a feature branch first.
- The branch has no commits ahead of `main`. Nothing to open a PR for.
- There are uncommitted changes the user hasn't asked to commit.

Run a build sanity check if the change is non-trivial:

```bash
bun typecheck
bun build
```

Don't open the PR with a broken build.

## 2. Read the PR template

The template is at `.github/pull_request_template.md`. Read it before composing the body — the section headings and checklist items are the source of truth, not your memory of them.

```bash
cat .github/pull_request_template.md
```

Mirror the template exactly:

- `## What does this PR do?` — one paragraph or a short bullet list. Link related issues with `Fixes #123` when applicable.
- `## How to test` — numbered, concrete reviewer steps (commands to run, what to click, expected outcome).
- `## Screenshots / screen recording` — if the change is visual, paste a recording link or note that one will be added. If purely non-visual (refactor, internal API), say so explicitly so the reviewer knows nothing is missing.
- `## Checklist` — copy the boxes verbatim, ticking the ones already verified.

## 3. Push and open

```bash
git push -u origin HEAD
```

Check for an existing PR first:

```bash
gh pr view --json url 2>/dev/null
```

If none exists, create it. Pass the body via HEREDOC to preserve markdown formatting:

```bash
gh pr create --title "short, scope-prefixed title" --body "$(cat <<'EOF'
## What does this PR do?

<one-paragraph description; link issues>

## How to test

1. <step>
2. <step>
3. <step>

## Screenshots / screen recording

<link or "N/A — non-visual change">

## Checklist

- [x] I've tested this locally with `bun dev`
- [x] My code follows the existing code style (run `bun check` to verify)
- [ ] I've updated relevant documentation (if applicable)
- [x] This PR targets the `main` branch

)"
```

Keep the title under ~70 characters. Use a scope prefix when there's an obvious one (`viewer:`, `core:`, `editor:`, `mcp:`).

If a PR already exists, print its URL and stop — don't recreate.

## 4. Report

Return:

- PR URL
- Title used
- Local typecheck/build status (if you ran them)
- A note for the reviewer if anything in the checklist is left unchecked
