On August 21, 2026, GitHub announced a public preview for the new GitHub Copilot experience in Slack. This update integrates the agentic capabilities of GitHub Copilot CLI and the GitHub Copilot app directly into the communication platform.
Users can now mention @GitHub in direct messages, channels, or threads to initiate an agent session. According to GitHub, the agent can use conversation context and permitted GitHub data to answer code questions, triage bug reports, investigate failures, and even implement changes within a secure cloud sandbox.
The integration supports asynchronous workflows. Copilot can continue working while the developer is offline, allowing the user to direct the session from Slack and then resume work in the terminal, IDE, or GitHub Copilot app when ready.
GitHub is a launch partner for Slack Code, a new channel type designed for agents. Copilot can create a dedicated channel that isolates the task from general conversation, allowing the team to review diffs, inspect previews, and iterate without noise.
Agent sessions are shared, enabling multiplayer collaboration. Teammates can see how prompts are used and learn from each other. Pull requests created by the agent are attributed to the ‘Copilot app' identity, subject to existing GitHub permissions.
The public preview is available to organizations on GitHub Copilot Business and Enterprise plans. To get started, an administrator must enable the Copilot cloud agent policy and install the GitHub app for Slack. For compliance, repository administrators can require an additional approval for any PR attributed to the Copilot app identity before merging.
