Honestly, I installed Hermes Agent last weekend, and while there isn't any "killer use case", the combination of "your little assistant agent on it's own machine" and good messaging integration is really quite cool.

I've set it up with it's own mailbox, and a git token to make PRs etc. So far I've set up a few automations (check thing X and message me if Y) but the combination of enough "intelligence" to be able to triage/suggest solutions, messaging via a standard messaging app, and a sandboxed environment for code execution, all packaged as "this is your helpful assistant" is fun.

In theory it's nothing I couldn't do with Claude Code + some integrations, but having all of that out of the box + setting the expectation that this is legitimately a helpful assistant you can message and email with any mad request you have does shift the way I see it.

Though yes, the more fun you have with it, the more of a security threat the whole thing becomes, and it's slightly terrifying. I briefly considered giving it view only access to my emails and decided that was just too high risk. But treat it as a vaguely clueless but not incompetent intern and works?
