Lumen

A vision-first browser agent with self-healing deterministic replay.

Vision-only loop

Screenshot → model → action → repeat. No DOM, no selectors.

Anthropic, Google, OpenAI, or any OpenAI-compatible endpoint.

Screenshot drop + LLM summarization. Stays in budget on long tasks.

agent.stream() yields typed StreamEvent objects for real-time UI.

Domain policies, action hooks, and completion verification gates.

Cache actions and replay them without the model. Self-heals when pages change.
