Presented Python runtime arc-cua for managing macOS interface

Developers have released arc-cua — a specialized Python runtime designed for creating agents that manage desktop applications. The tool is oriented towards working in the macOS environment and provides low latency when executing user commands.

The system architecture separates high-level logical reasoning and low-level interaction with the graphical interface. A built-in OCR system is used to analyze the screen state, and the macOS accessibility API is used to control elements. This allows the agent to read the window structure and imitate user actions with high accuracy.

JEV is used as the standard backend for decision-making in arc-cua. This combination allows complex cognitive tasks to be delegated to specialized models, leaving the runtime to handle the technical execution of clicks, text input, and menu navigation.

The project is distributed with an open source code and is intended for developers creating autonomous assistants for automating routine operations on a computer. The use of local data processing tools minimizes delays that occur when transmitting screenshots and commands to remote servers.

The emergence of such solutions simplifies the creation of agents that can interact with any software without the need for integration through APIs. The separation of logic and execution is a key trend in the development of computer vision and workflow automation systems.
