The README says TypeSafe's Jev selects an operation and element from observed page controls, while a small language model generates text for TYPE_TEXT.\n\nThe README lists CLICK, TYPE_TEXT, SELECT, SCROLL_UP, SCROLL_DOWN, WAIT, DONE and BLOCKED. The README says the default agent loop uses structured state rather than screenshots and describes page-freshness and target checks before execution.\n\nThe README shows a Python Agent class, a local inspector and example scripts for Google Flights and Wikipedia tasks. The README calls the implementation an MVP and lists excluded browser features.","intended_users":"Developers who want to run or study a browser agent that works from a numbered table of page controls.","example_tasks":"Start the local inspector with uv run jev and run the demo automatically.\nUse Choose next in the inspector to pause before each action executes.\nCreate an Agent with a start page and a goal, and read the status of each state it yields.\nRun examples/run.py with a start page and a goal to try a different task.\nRun examples/flights.py with --keep-open to search for flights without booking one.","setup_instructions":"The README says to clone the repository and change into its folder, then run uv sync, copy the example environment file with cp .env.example .env, add TYPESAFE_API_KEY and TEXT_MODEL_API_KEY, and run uv run jev. Then open the local address on port 8766 and start the demo. The README says Chrome connects through Browser Harness, which uv sync installs. The README says to run uv run browser-harness --doctor if it needs connecting. The README has the exact commands.","limitations":"According to the README, setup needs a TypeSafe API key and a text-model API key, and you allow remote debugging in Chrome when prompted. The README calls the project an MVP. It says the DOM reader handles common HTML and ARIA controls, not the full accessible-name specification, and that shadow roots, frames, canvas, uploads, pop-up tabs, nested scrolling and arbitrary keyboard widgets remain outside it. It says owned tabs share the existing Chrome profile, that after a DONE choice an independent check of the outcome is still required, and that its timing results are three repeats of one task on one browser profile, not a general reliability benchmark. It says live examples and recording scripts make paid API calls. The repository can change at any time; check its README before you install.","data_handling":"According to the README, each decision cycle makes one TypeSafe request that uses the observed element table, and a small language model writes the text for TYPE_TEXT. The README says the default agent loop consumes structured state without screenshots and that the inspector opts into screenshots. The README says it sends visible text, and that offscreen article bodies and footers do not fill the model context. It says credentials and raw traces stay ignored. The README does not mention telemetry.","compatibility":"According to the README, it connects to Chrome through Browser Harness, which uv sync installs, and uses TypeSafe's Jev for its decisions.
