name: computer-use description: Control the macOS desktop compatibility: "Designed for Vellum personal assistants" metadata: emoji: "🖥️" vellum: display-name: "Computer Use" category: "system" activation-hints: - "User asks the assistant to click, type, drag, or interact with the macOS GUI directly" - "User wants control of a desktop app with no CLI or API alternative (games, design tools, visual workflows)" - "User wants screenshots or visual inspection of what is currently on screen" avoid-when: - "Task can be done via a more specific skill (gmail, calendar, contacts, terminal-sessions) or a CLI / API call"
This skill provides the computer_use_* action tools for controlling the macOS desktop. CU tools run through the main agent loop via HostCuProxy.
The skill is internally preactivated for conversations with a connected desktop client.
Tools in this skill are proxy tools - execution is forwarded to the connected macOS client, never handled locally by the assistant.
