GitHub Copilot SDK becomes the Microsoft Copilot SDK, the programmable interface to the Copilot harness shared across Microsoft and GitHub
The SDK moves from GitHub to Microsoft; existing users need no code changes for now, but should know whose roadmap it will follow.
// Key points
- The GitHub Copilot SDK is being renamed the Microsoft Copilot SDK, the programmable interface to the Microsoft Copilot harness, the shared agent foundation across Microsoft and GitHub products.
- The repository is planned to move to the Microsoft organization, with branding and docs updated; the migration happens in phases with no dates given.
- Existing package names and namespaces stay for now, existing users need no immediate changes, and support is unchanged.
Builder's takeRead with the Copilot harness in Foundry from the 10-29 issue, Microsoft is turning GitHub's agent foundation into a company-wide platform. Teams that wired up the SDK with the server-to-server auth from the 10-28 issue should pin the version, watch the repository move announcement, and upgrade together on the day the package names actually change.
