Slack launches code channels where teams and AI coding agents build together

Slack launched Slack Code on August 20, 2026, dedicated “code channels” where software teams and AI coding agents such as Claude, Devin and GitHub Copilot plan, write and review software together in the same workspace. The feature is available on any Slack plan starting today.

The launch pushes agentic coding out of individual developer tools and into the shared channel where teams already talk. Mentioning a supported agent spins up a project-specific code channel with live diffs, planning documents and HTML previews; when the work is finished, the channel auto-archives with an audit log of what the agents and humans did.

At launch the feature supports Claude, from Anthropic; Devin, from Cognition; GitHub Copilot; and Vercel’s agents, with ChatGPT integration described as coming soon. The pitch from Slack, a Salesforce company, is that keeping agent work in a visible channel makes it reviewable rather than hidden inside one engineer’s editor.

“Slack is a strategic part of a broader GitHub promise: humans set direction, agents close the loop,” GitHub chief product officer Mario Rodriguez said in the announcement.

The framing sidesteps the harder question of how much oversight a chat channel really provides. Live diffs and audit logs make agent actions legible, but they do not by themselves catch a bad change; a human still has to read the diff and decide. Whether teams treat code channels as genuine review or as a fast lane that rubber-stamps agent output will determine if the format improves software or just ships it faster.
