Ask HN: AI agents in Slack can write but can't remember. Anyone else?

We're an AI startup running multi-agent teams in Slack. Our agents review code, discuss architecture, and ship features, all in Slack channels. The irony: Slack AI already vectorizes all messages for semantic search internally. But there's no developer API to query it. So we built our own pipeline: pull messages, embed externally, in pgvector, sync continuously. Rebuilding what Slack already has from scratch. We're reaching out to Slack leadership to request a simple semantic.search API endpoint. One endpoint that would make Slack the memory layer for every AI agent team.
