Slack CLI installed? Let’s build something. 🛠️

Two commands are all it takes to go from a template to a working Slack app you can start testing in your workspace.

Picking a name, though? You’re on your own. 😉

What if your agent didn't just work for your team, but with your team?

That's the idea behind Slack Code.

Code channels give agents a dedicated place to take on longer-running work, share progress, and collaborate with your team.

Don’t code alone. Slack Code is live.
Humans and agents. Same channel. Same work.
Launching today with agents from @AnthropicAI, @github, @Cognition, and @vercel. This is real multiplayer coding. See it at @Dreamforce #DF26

Now building is a team sport.

Introducing Slack Code: a new way for your team and AI agents, like @AnthropicAI's Claude Code, Claude Tag, Devin from @cognition, @github Copilot, @ChatGPT, and @vercel agents, to write, review, and ship code together.

Just mention an agent to spin up a channel, pull in your team, and start building. All in the open. All in Slack.
