Learn how to master @claudeai Duet in the next 18 minutes. Duet is Claude’s new proactive assistant. It’s in beta right now, and I’ve been testing it early. The big difference is that Claude waits for you to ask, and Duet goes and finds the work. It’s already connected to your Claude account, so your connectors, instructions, and artifacts carry over on day one. I’ve been really surprised by how quick it is. A new Slack message, email, or calendar invite comes in, and Duet often suggests a task or next step before I’ve even opened it. Most people will open it and chat with it like regular Claude. That leaves most of the value on the table. Duet gets really good once you onboard it to your routine tasks and give it a few jobs to own. I set mine up around four channels that cover what it takes to be great at my (or your) job: To-dos: a weekly board, built as an artifact, that Duet checks with me three times a day Meetings: prep before every call, action items after, and a Friday retro on how I ran them Goals: my quarterly OKRs, with a weekly check-in on how I’m pacing Coaching: an end-of-day read of my Slack, email, and calls, with what went well and what to fix tomorrow Each one feeds the others. Meeting notes turn into to-dos. To-dos roll up to goals. Coaching looks at all of it. Two tips before you start: 1) Connect your Slack. It makes the experience so much better. Duet gets way more context about your work and starts finding real ways to help. 2)Manage permissions in the Claude app, not in Duet. Put anything that sends or deletes on “Ask me.” Reading can stay on “Always allow.” Here’s the full walkthrough, from zero to hero: 00:00 What Claude Duet is 00:35 Settings, connectors, and permissions 03:49 Build your weekly to-do board 06:29 Meeting prep, recaps, and retros 11:46 Track your quarterly goals 13:37 Set up a daily coach 15:21 How the four channels work together
