There’s a specific window where tool-connection prompts land well: after a user understands the product’s core value, but before their workflow solidifies without the integrations. Cowork’s home-screen modal hits that window. It appears only for users who haven’t yet connected any tools, catching them at the moment when the gap between their current setup and a more powerful one is most visible. What makes it worth studying is how the CTA is designed. Rather than routing users to a settings page, ‘Let’s go’ initiates an active, guided process where the product does the heavy lifting.
