computer-use
The computer-use skill enables Claude to control a connected macOS desktop through proxy tools that forward execution requests to the client. Use this skill when the assistant needs to interact with the desktop environment, including taking screenshots, clicking, typing, or manipulating windows on the user's Mac. The skill activates automatically in conversations with a connected desktop client.

This skill provides the computer_use_* action tools for controlling a connected 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 a connected desktop client and is never handled locally by the assistant.
