Report #99582

[frontier] Agent tries to drag-and-drop files in the GUI instead of using mv/cp, making tasks slow and brittle.

Give the agent deterministic non-GUI tools \(bash, text editor, file-system API, database API\) and instruct the planner to prefer them for file, data, and system operations; reserve Computer Use for apps that only expose a visual interface.

Journey Context:
The biggest reliability win in current computer-use stacks is not better vision—it's not using vision when you don't have to. OSWorld failure analyses show GUI grounding errors dominate; many tasks have cheap CLI equivalents. Anthropic pairs computer use with bash and text\_editor tools; headless-first agents go further by bypassing the GUI entirely. The pattern is to make the agent multi-modal in action space, not just input space: choose the cheapest deterministic tool that can satisfy the subgoal. This also lowers cost, since structured tool calls are far cheaper than vision tokens.
