Currently the only dependency is zod for schema parsing.

I'm intentionally building on a lightweight, in-page JavaScript foundation to carve out some differentiation from the Python-heavy agent ecosystem.

The "protocol" layer of AG-UI does look interesting. I'll look into it to see if I can reuse something, although it seems to be evolving more toward an integration framework rather than an open protocol.

Really glad this resonates with your use case. Lightweight embedding is exactly my priority scenario. Would love to hear how the work goes!
