Slack wants to be primary place people do their work. And they're almost there... It's certainly where you "work" (communicate) with people, it's where many engage with and/or control other platform like project trackers, and it's increasingly the place you interact with whatever AI agents your company uses. It makes perfect send they want to bring the coding agent into the fold (into their UI) as well. And, given Anthropic's release of Claude Tag, they're probably not wrong about that.
