Limitations

The documented embed attributes expose the model API key to every visitor; production deployments need a restricted disposable key or a controlled server proxy.
The agent can read page markup, click controls, fill fields, and navigate links, so it must not be embedded on sensitive pages without a threat model and strict provider controls.
Ships as a roughly 250 KB gzipped standalone bundle with its own Preact and LangChain runtime rather than integrating into the host Preact tree.
