dsh-computer-use

dsh-computer-use addresses the problem of agents controlling macOS desktop applications without interrupting the user. Many automation approaches can click and type, but they often move the system cursor or steal foreground focus. This plugin starts with observation, builds a clear target from the accessibility tree and app/window metadata, and routes input to the selected application whenever possible, allowing an agent to work with background native apps while keeping the user's cursor and current workflow largely untouched.

Its core capabilities include fresh accessibility observations, actions bound to exact state, semantic accessibility interactions before pointer fallback, and process- or window-targeted click, scroll, drag, and keyboard input when needed. Successful actions return updated evidence instead of blindly replaying old steps. The plugin also separates read and control access by application, session, and scope, requires one-time confirmation for sensitive actions, and can show a separate software cursor to visualize what the agent is doing.

It is a good fit for developers, automation builders, and advanced users who want DeepSeek Harness agents to operate native macOS applications in a controlled, auditable way, especially when background operation and clear permission boundaries matter. For browser workflows, APIs, CLIs, or dedicated application integrations, those narrower tools remain the better choice.
