GitHub CTO Vlad Fedorov says API improvements will notify agents of changes rather than making them repeatedly poll, alongside better partial checkout to load only the code a task needs. The work is planned for the first quarter of 2027, not announced as fully deployed. He also describes investment in stacked pull requests and Copilot code review to highlight likely errors as code generation grows. Fedorov says GitHub does not merge internally without human review, and engineers remain responsible for their changes and subsequent system behavior. These request-efficiency plans are distinct from the earlier storage-scalability redesign.
