I'm only using NanoClaw, but I like that I could (and did) just review the code it has, and that it uses containers for each agent (so I can have different WhatsApp groups working on different things and they can't interfere with each other), and that I could (and did) just swap those containers out easily for guix shell containers.

I am pretty confident that I know how the agent containerization works. In general there's really not a lot of complexity there at all.

If one wants, one can just (ask Claude to) add whatever functionality, or (and that's what I did) just use Claude skills (without adapting NanoClaw any further) and be done with.

What is annoying is that their policy is instead of integrating extra functionality upstream, they prefer you to keep it for yourself. That means I have to either not update from upstream or I am the king of the (useless so far--just rearranging the deck chairs) merge conflicts every single time. So one of the main reasons for contributing to upstream is gone and you keep having to re-integrate stuff into your fork.
