name: update-buttercut description: A skill to automatically download and install the latest ButterCut version from GitHub while preserving libraries. Use when user wants to check for updates or update their installation for new features.

Skill: Update ButterCut

Updates ButterCut to the latest version. Uses git pull if available, otherwise downloads from GitHub.

Before updating, always make a backup and encourage the user to save it to a location outside the ButterCut directory. Verify the most recent backup exists and offer to copy it to their Desktop or iCloud Drive.

Workflow

1. Check current version:

cat lib/buttercut/version.rb

2. Check if git repo:

git rev-parse --git-dir 2>/dev/null

3a. If git repo exists:

# Check for uncommitted changes
git status --porcelain

# If changes exist, STOP and inform user to commit/stash first

# Pull latest
git pull origin main
bundle install

3b. If not git repo:

# Download latest
curl -L https://github.com/barefootford/buttercut/archive/refs/heads/main.zip -o /tmp/buttercut-latest.zip
unzip -q /tmp/buttercut-latest.zip -d /tmp/

# Update files (excludes libraries/)
rsync -av --exclude 'libraries/' --exclude '.git/' /tmp/buttercut-main/ ./
bundle install
rm -rf /tmp/buttercut-latest.zip /tmp/buttercut-main

4. Verify:

cat lib/buttercut/version.rb
bundle exec rspec

If tests fail, STOP and report issue. Show old and new version numbers.
