macos-service

A Claude Code skill that enables Claude to create macOS Quick Actions (Services) programmatically — no Automator GUI needed.

What It Does

When you ask Claude Code to create a Finder right-click action, this skill provides it with:

• The exact .workflow bundle structure and XML plist templates
• Tested patterns for shell scripts running inside Automator (PATH resolution, file handling, user feedback)
• Common gotchas and their solutions (e.g., notifications don't work in Automator — use dialogs instead)
• UTI type reference for file type filtering

The result is a Quick Action that appears in Finder's right-click > Services menu and runs a shell script on the selected files.

Example

"Create a right-click service that converts selected images to WebP format"

Claude will build and install a .workflow bundle to ~/Library/Services/ that accepts image files, runs an ffmpeg/cwebp conversion, and shows a dialog when done.

Installation
