Your agent belongs in the conversation.
Most of my texting happens over iMessage, so when I set up my Hermes AI agent it made sense for it to live there too. Claw Messenger was the most reliable way I found to make that work. My agent handles day-to-day messages for me (reminders, updates, quick back-and-forths) and it just works in the background without me thinking about it.
