SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Manually operating and navigating macOS desktop apps for repetitive tasks is time-consuming and prone to human error. This Skill eliminates that manual work by enabling automated, precise interactions with any windowed macOS application.

Core Features & Use Cases

  • Cross-App Desktop Automation: Interact with any windowed macOS app including Spotify, Discord, Slack, Notes, Calendar, VS Code, and more via accessibility-driven commands.
  • Precise UI Interaction: Use accessibility tree element IDs or screenshot coordinates to click, drag, type, scroll, and fill form fields reliably across different app types.
  • Use Case: Imagine you need to send a weekly status update to 3 Slack channels, add 12 recurring tasks to your Linear project, and queue a 4-hour focus playlist in Spotify. Use this Skill to automate all these repetitive interactions in seconds without manual clicking or typing.

Quick Start

Ask the AI to use the stella-computer skill to open your Notes app, create a new entry titled "Grocery List", and type "Milk, eggs, bread, coffee" into the body.
