No one is going to churn Slack for this just because it is "Agent First". Slack is more than good enough to tag Agents and will fill in the missing pieces slowly
Slack's approach is NOT good enough, because the version of the Agent that lives in Slack cannot see the context of the Agent that lives inside Cursor on my developer laptop. They might be clones with identical brains, but they can't talk to each other or compare notes.
So why can't the cursor instance on your laptop have a slack bot? I've had a slack bot on my build machine written in chicken-scheme of all things for years, I feel like the great people (or clankers?) at cursor ought to be able to figure this one out
It could! An MCP would actually be great but Slack would prefer to sell us their own AI integration product so (1) they make it difficult and more importantly (2) it's against their terms of service
We pay them a LOT of money every year and they would absolutely notice the indexing at the level we'd need to do to make this work ourselves, so the answer is "because Slack is preventing us".
