> Personally, I’ve replaced OpenCode with a thin wrapper around Pydantic-AI as the pythonic analogue to Pi-Agent for headless use via Hermes

That's really interesting. I like Pydantic AI a lot and wondered why all of the harnesses seem to be written in Javascript instead of it. What do you use it for headless, though? I haven't tried Hermes or similar yet, so don't have a handle on what you do with them.

I initially went with OpenCode's v2 client-server rewrite until I noticed how that wasn't ready for prime time.

Turns out I didn't need a fancy TUI at all when desktop, web and mobile interfaces are already provided by or available for Hermes.
