Anthropic just launched Claude Duet, an always-on agent on Claude Opus 5.5. It scans your email and calendar every morning, drafts replies, and works in its own cloud browser even when your phone is off. Catch: US-only preview, and background checks eat into your Claude limits. The agent that messages you first is the new race. My take: approval-before-action is the only model I'd trust, but I'm not spending my limits on scans I never asked for.
