If your input arrives before the run finishes, it should stop with `browser-action-preempted-by-user`. - -```bash -cate browser jev 'Replace Greeting with Goodbye and click Save. Finish when the saved greeting shows Goodbye' --max-steps 5 -``` - -## Notes - -- Each run uses the selected browser panel's active tab, then stays bound to that tab. -- Avoid interacting with the browser during a normal run; user input stops Jev. -- Each field value must be one word from the prompt. Multiword values and generated text are unsupported. -- `--max-steps` counts browser steps, not model calls. -- Runs have a 180-second timeout; prompts can contain up to 8,000 characters. -- Only `done` exits with code 0. `--json` includes the status, actions, and model-call count. -- If Jev reports `uncertain` or `blocked`, try a shorter prompt with one clear outcome.
