About Slack
Slack rebuilds its developer platform around shipping in-channel AI agents.
Slack is well into a platform pivot, restructuring its CLI, Block Kit, and APIs around AI agent use cases. The 4.0.0 release in April formalized this with an agent-scaffolding command, sample agent apps, and a live-reloading dev workflow. Recent additions — streaming chat APIs, Card/Carousel/Alert blocks, and continued MCP server expansion — show the surface area for in-Slack agents widening fast.
