查看 README 依据

cp .env.example .env # Add TYPESAFE_API_KEY and TEXT_MODEL_API_KEY. uv run jev ``` Open **http://127.0.0.1:8766** and click **Start demo → Run automatically**. The inspector shows numbered elements, operation probabilities, target probabilities, and executed actions. **Choose next** pauses before execution. Chrome connects through [Browser Harness](https://github.com/browser-use/browser-harness), installed by `uv sync`. Run `uv run browser-harness --doctor` if it needs connecting. Allow remote debugging in Chrome when prompted.

`TEXT_MODEL_API_KEY` is an OpenRouter key in the example configuration. The current demo uses `inception/mercury-2.5` with reasoning disabled. Gemini, GLM, and DeepSeek can also use the OpenAI-compatible text helper; configure the appropriate model, endpoint, and reasoning setting. ## Use the library ```python from jev_ultrafast import Agent with Agent( "https://www.google.com/travel/flights?hl=en", "Find one-way flights from Zurich to London on September 20, 2026, " "for one adult in economy. Stop when matching flight options are visible.", ) as agent:

已知限制

当前MVP不支持Shadow roots、frames、canvas、上传、弹出标签页、嵌套滚动和任意键盘控件。

查看 README 依据

A `DONE` choice still requires independent outcome verification. The DOM reader handles common HTML and ARIA controls, not the full accessible-name specification. Shadow roots, frames, canvas, uploads, pop-up tabs, nested scrolling, and arbitrary keyboard widgets remain outside this MVP. Owned tabs share the existing Chrome profile. ## Development ```bash uv run ruff check . uv run pytest node --check jev_ultrafast/static/app.js node --check jev_ultrafast/snapshot.js uv build ```
