Does anyone know what the impact on prompt caching is? I like the idea of dynamic tool/skill sets, but wonder if it needs to be part of the new session workflow where you would choose a group to activate rather than this dynamic.

I'm pretty sure it's a bad idea because each time you connect and disconnect tools, you are hitting a full cache miss on the full context, that will be probably more expensive than having these tools in place from the very beginning.
