It isn't ones duty to develop for everybody. If someone makes something for their own use case and shares it, that's fine.

Codex and Gemini have ACP servers already:

In fact Codex, in OpenAI fashion, have their own protocol as well:

Opencode too. These tools are already so programmable and embeddable, it's just Claude Code is a sticking point. But maybe it would be useful to provide a unified CLI and Daemon for all of them.

For someone paying nothing for something that costs nothing, you have way more than nothing to complain about. Not appropriate.

https://github.com/ehrlich-b/wingthing - Here's my version of this idea which is agent agnostic. Not exactly the same idea, "sandbox'ed persistent agent", in my case available over the web with xterm.js (though you can also just run locally).

Can't you just tell your AI tool of choice to just port it? One thing I like about AI is that now I can easily roll my own or take an open-source project and customize it really fast with very little commitment on my end. Instead of everyone having to use the exact same tools, now we can customize it to our liking--at least for now

I’ve made something very similar that is almost backend-agnostic: https://github.com/ayourtch-llm/tttt - and it does auto inject the MCP in case of Claude, but it is trivial to adapt to other backends.

Opencode already supports continuing old sessions with ctrl-x, l.
