The AI Reviewer Gets Its Own Locked Workshop
GitHub added head-branch instructions, custom setup steps, separate runners, and a default firewall to Copilot code review.

Summary
GitHub added head-branch instructions, custom setup steps, separate runners, and a default firewall to Copilot code review.
Copilot code review now reads instruction files from a pull request's head branch, including AGENTS.md, and recognizes additional review-guidance filenames. Repositories can define a dedicated setup workflow, while organizations can configure review runners separately from the cloud coding agent. Network access is firewalled by default on supported hosted runners; self-hosted runners do not currently receive that firewall.
