Yes, that's a significantly less efficient way to manage persistent sessions

I'm pretty sure "how do we disallow running our agents in screen sessions" is on a jira board at some places

Right, that's the "most inefficient way possible" (though personally I disagree, there are more inefficient ways to be found).

You could put the transport protocol on the blockchain, I suppose

You are making me more creative.

we can upload snapshot of zip files to blockchain, then notify customer via servers

I'm probably 10 years out of date. Are ethereum smart contracts still a thing? I'm sure you could deploy one of those for every agent session to handle the notifications

Even better, train an entirely new LLM with your prompt added to its data set. It will be imbued with its own latent sense of purpose. All you need to do after that is type "let there be light!"
