Anthropic Shipped Claude Channels. Your AI Agent Can Now Text You Back.
Until very recently, every interaction with an AI agent had the same shape. You sit down. You open the tool. You give it a task. You wait. You check. You iterate. Every cycle requires your presence.

By the time a live stream was done discussing it, the counter was climbing by a thousand stars every ten minutes. Nobody in the room could remember seeing anything grow that fast. Because nothing had. I watched it happen in real time. I'd met the two engineers behind it the weekend before at an AI hackathon in San Francisco. Within 72 hours of shaking hands, they'd built the fastest-growing repo in GitHub history —...
