This is far from perfect but we're in this weird transition phase where none of the major AI tool providers are really focusing much on team use of their stuff. But I expect that will start changing soon.
Current tools mostly focus on individuals doing things in isolation. And of course in a team there's more to collaborating than throwing stuff at each other via github. A central repository of company skills is merely our way of improvising a solution.
I find it interesting that Anthropic hired a few of the key people behind Zulip recently. Team chat with tightly integrated AI tools could be a missing piece here. Team communication flows and processes, including ways of working and guardrails are sort of the next piece of the puzzle here. Going from everyone doing their own thing to teams and companies doing things together is going to be a bit of a journey.
