It’s trivial to build something that does what this describes. I’m sure there’s more too it, but based on the description the pieces are already there under permissive open source licenses.
For a clean implementation I’d look at socket-activated rootless podman with a wasi-sdk build of Python.
It was an afternoon to prototype, followed by a lot of work to make it scale to the point of giving everyone who lands from HN a live CPython process ;)
This is the sort of thing that would touch a lot of my data so I’d much prefer to have it self hosted but you mention Claude rather than deepseek or mistral so know your audience I guess.
Fair enough. Our audience is businesses rather than consumer, so our equivalent to self-hosting is that we can run it in a customer's cloud.
We mention Claude a lot because it is a good general coding model, but this works with any LLM trained for tool calling. Lately I've been using it as much with Gemini Flash 2.0, via Codename Goose.
