Slack Code brings AI coding agents into shared team channels
Slack launched Slack Code on August 20, and the idea is straightforward: AI coding agents now live inside shared channels where everyone on the team can follow along.
How It Works
Tag an agent from a conversation and Slack spins up a project-specific code channel for that task. The channel has four tabs: the conversation, the plan, code diffs, and a live HTML preview of what the agent built. When the task is done, the channel archives itself and leaves a searchable audit log.
Supported agents at launch include Anthropic’s Claude, Cognition’s Devin, GitHub Copilot, ChatGPT, and Vercel’s agent. Access to each partner agent is purchased separately. The Slack Code feature itself is available on all Slack plans, including free ones.
The Visibility Angle
Slack VP of product Katie Steigman framed the channel format as a review layer, not just a communication one. She said it lets colleagues inspect an agent’s output before it ships, and noted she tags an engineer on every pull request she opens herself.
On permissions, agents inherit the credentials of the user who invokes them. There are no elevated admin permissions for agents. Merging code into production still requires human approval inside the channel.
What Else Is Coming
Slack is also rolling out agent DMs, an Agents tab showing live status with a stop option, and an Add to Slack flow for agents built on Lovable, n8n, and LangChain. APIs for code channels are expected to open to outside developers later, with potential use cases beyond software development in areas like marketing and legal work.
For solo operators and small teams already living in Slack, this removes the need to context-switch into a separate coding environment to see what an agent is doing.
