Introducing Slack Code
Now building is a team sport
Slack Code brings you, your teammates, and AI agents together to build in the open. Just mention an agent to spin up a code channel, pull in your team, and watch the work come to life. Watch the demo now.

Overview
The "Buy now" button label is difficult to read in dark mode. Support flagged reports of the text nearly disappearing against the button's pink background on some devices.
Root cause
The button's label color was set to a light grey value intended for dark-mode surfaces, but it was mistakenly applied to the button text as well. Against the yellow background, this produced a contrast ratio well below accepted accessibility thresholds. The button's background color is not affected by theme switching.
Turn AI work into teamwork
With code channels, AI work isn’t a solo task. Your team can guide agents together in real time. And since agents start with the context of your team’s conversations and knowledge in hand, they can hit the ground running.
You bring the idea. The agents bring the code.
Slack Code turns any idea into working code in a code channel. Just describe what you want, and an agent builds it while your team follows along, weighs in, and approves the result.
Nothing ships without your sign-off
Every message you send to an AI agent gets the same security treatment as everything else in Slack — EKM, DLP, Discovery APIs and all. You're always the one reviewing, adjusting, and giving the go-ahead.

Agents work better in Slack
Your agents shouldn't feel like tools, they should feel like teammates. In Slack, they are easy to find, easy to keep up with, and always ready to jump back in.
Find agents faster
All your agents live in the Agents tab. Check in on sessions, track live status, and see when an agent needs you.
Keep conversations clean
In Slack, agents do their work quietly in the background, so you can stay focused on yours.
Pick up where you left off
Smarter threads automatically create clear titles, making past conversations easy to find and revisit.
"Slack is a strategic part of a broader GitHub promise: humans set direction, agents close the loop. That has to be true wherever developers are working, which is why we're bringing Copilot into the flow of conversation in code channels to help teams turn shared intent into shippable software."
Frequently Asked Questions
Slack Code creates a temporary channel, called a code channel, where teams and agents work together on a specific task or project. An agent creates one when it starts working, giving you and your team a dedicated place to collaborate without cluttering your main channels. When the work is done, the code channel gets archived automatically, while the context stays searchable.
No. Code channels follow Slack’s enterprise-grade security and permissions model. Agents only have access to the conversations and information they’re allowed to see, based on the controls already set up for your workspace.
Yup! You don’t need to know how to code to work with agents. Code channels make it easy for anyone to see what an agent is building, review previews, and share feedback directly in Slack.

Developers can build agents that feel at home in Slack. New APIs and tools make it easier to create rich agent experiences, including dedicated spaces in the Agents tab, focused conversations, and smarter threads that help people find their way back to previous work.
