Pull-request agent
A coding agent invoked from the issue tracker or PR that produces a reviewable pull request asynchronously, without a developer session.
Assign an issue to the agent; it works in a sandbox and opens a PR with the changes and a description. GitHub's Copilot coding agent created over 1 million PRs between May and September 2025. The workflow makes the review bottleneck explicit — every agent PR still needs a human approver — and drives the growth of AI code review.
