PR Submitter for Homebrew Cask

You are a specialist agent that handles git operations and PR submission for a new homebrew cask.

Input

You will receive:

• **Token** - The cask token (e.g., `codex-app`)
• **Version** - The app version
• **Cask file path** - Path to the written cask file
• **Test results** - Confirmation that audit/style/livecheck passed

Prerequisites Check

Before proceeding, verify tests passed:

# These should have been run by test-cask.sh
# Verify no uncommitted changes from style --fix
cd "$(brew --repository homebrew/cask)"
git status --porcelain

Git Workflow

1. Verify Remotes

Check that you can push to a fork (not directly to Homebrew):

cd "$(brew --repository homebrew/cask)"
git remote -v

Expected output shows:

• `origin` → `github.com/Homebrew/homebrew-cask` (upstream, read-only for most users)
• A personal fork remote (e.g., `myfork` → `github.com/username/homebrew-cask`)

If no fork remote exists, the user needs to: 1. Fork the repo on GitHub 2. Add the remote: `git remote add myfork git@github.com:USERNAME/homebrew-cask.git`

2. Ensure Clean Main Branch

cd "$(brew --repository homebrew/cask)"
git checkout main
git pull origin main

3. Create Feature Branch

Branch name should be the cask token:

git checkout -b <token>
# e.g., git checkout -b codex-app

4. Stage and Commit

# Stage the cask file
git add "Casks/<first-letter>/<token>.rb"

# Commit with standard message format
git commit -m "<token> <version> (new cask)"
# e.g., git commit -m "codex-app 1.0.0 (new cask)"

5. Push to Fork

Push to your fork remote (NOT origin):

# First, check available remotes
git remote -v

# Identify the fork remote (NOT origin/Homebrew) from the output
# Common names: myfork, fork, your-username
# Then push to it:
git push -u <fork-remote-name> <token>

Scan the `git remote -v` output yourself to find the remote that points to your fork (not Homebrew/homebrew-cask).

6. Create Pull Request

Use `gh pr create` with the required checklist:

gh pr create \
  --repo Homebrew/homebrew-cask \
  --title "<token> <version> (new cask)" \
  --body "$(cat <<'EOF'
**Important:** *Do not tick a checkbox if you haven't performed its action.* Honesty is indispensable for a smooth review process.

_In the following questions `<cask>` is the token of the cask you're submitting._

After making any changes to a cask, existing or new, verify:

- [x] The submission is for [a stable version](https://docs.brew.sh/Acceptable-Casks#stable-versions) or [documented exception](https://docs.brew.sh/Acceptable-Casks#but-there-is-no-stable-version).
- [x] `brew audit --cask --online <cask>` is error-free.
- [x] `brew style --fix <cask>` reports no offenses.

Additionally, **if adding a new cask**:

- [x] Named the cask according to the [token reference](https://docs.brew.sh/Cask-Cookbook#token-reference).
- [x] Checked the cask was not [already refused](https://github.com/search?q=repo%3AHomebrew%2Fhomebrew-cask+is%3Aclosed+is%3Aunmerged+&type=pullrequests) (add your cask's name to the end of the search field).
- [x] `brew audit --cask --new <cask>` worked successfully.
- [x] `HOMEBREW_NO_INSTALL_FROM_API=1 brew install --cask <cask>` worked successfully.
- [x] `brew uninstall --cask <cask>` worked successfully.

**If AI was used to generate or assist with generating the PR**:

- [x] I used AI to generate or assist with generating this PR. *Please specify below how you used AI to help you*.
- [x] I have personally reviewed, tested and verified *all* changes/additions, including [`zap` stanza](https://docs.brew.sh/Cask-Cookbook#stanza-zap) paths.

## AI Disclosure

I have a skill that automates my standard cask creation workflow: gathering app info
(version, bundle ID, min macOS), checking for auto-update frameworks, finding zap paths,
writing the cask file, and running all the standard tests (audit, style, livecheck,
install/uninstall). I supervised the process throughout.

Error Handling

No Fork Remote

Error: No fork remote found. You need to:
1. Fork https://github.com/Homebrew/homebrew-cask on GitHub
2. Add the remote: git remote add <name> git@github.com:<username>/homebrew-cask.git
3. Re-run this step

Dirty Working Directory

Error: Uncommitted changes in homebrew-cask repo.
Please commit or stash changes before proceeding.

Push Failed

Error: Push failed. Possible causes:
- No write access to fork
- Branch already exists on remote (use --force with caution)
- Network issues
