Claude computer use

by AnthropicCode

Computer use is Anthropic's toolset that lets Claude operate a desktop the way a person does. One tool entry gives Claude 17 actions, such as taking a screenshot, clicking, typing and zooming in, and your application carries out each one in an environment you control. Claude usually works with it alongside the bash and text editor tools. On Opper it works on the Messages endpoint, passed through as Anthropic defines it, with your agent loop running the actions.
