What shipped? GitHub Copilot cloud agent sessions are now available in Microsoft Teams as a public preview, alongside today's Slack launch.
What changed? Mention @GitHub in a Teams channel, thread, or direct message to start a collaborative agent session anyone in the conversation can see and steer. Copilot can answer code questions, triage issues, investigate failures, implement changes in a secure cloud sandbox, and open pull requests. It creates a dedicated code channel so the work doesn't clutter the original discussion — and the session continues asynchronously if you step away.
Repository administrators can require an additional approval on PRs created by the Teams integration, keeping a human in the loop before agent-authored code ships.
The integration uses GitHub Copilot cloud agents (paid plans, public preview). Cloud sandbox usage is billed separately and can be controlled with product-level budgets.
Why a builder cares. Teams is the collaboration layer for most enterprise dev organizations. Dropping Copilot's agentic capabilities there — alongside Slack — means your team's shared intent in a standup or meeting can become shippable code without leaving the conversation. The compliance controls (extra approval gates) make this viable for regulated environments.
