# System One Computer Use > Prototype Python agent that controls your mouse and keyboard from screenshots, using JEV to choose each next action, with a local dashboard for runs and reports. System One Computer Use is an open-source Python prototype from the GitHub user brainstormity that operates a computer through screenshots. In a loop it captures the screen, asks JEV what to do next, and carries out the chosen action with pyautogui. The README labels it a proof of concept, not for production use. ## What It Is A computer-use agent contained in a single file, jev_agent.py, plus a small standard-library web dashboard (dashboard.py) for running tasks and reviewing reports. Each step, JEV picks an action such as click, type, press Enter, scroll, open a website, or stop when done. The agent is run from a task string in the terminal or from the dashboard at 127.0.0.1:8000. ## How the Loop Works Each step takes a screenshot with mss and sends one JEV request containing three questions about the same image: which action comes next, where on screen to click, and which text to type. JEV only chooses from options and never writes free text. The options are the defined actions, text drawn from the user's task (quoted text and 1-3 word phrases), and websites named in the task. As a result, text on a web page cannot make the agent type something absent from the task. After acting, the agent waits for the screen to settle and saves the step to runs/
