Streamlining pull request review timelines

Collapsed Copilot review timeline events reduce noise in pull request conversations so teams can find important review information faster during collaboration.

Why the human is still essential here

Humans still prioritize findings, discuss tradeoffs, and resolve review comments; AI and UI changes only improve navigation and signal clarity.

Copilot code review: AGENTS.md support and UI improvements

Copilot code review now supports repository-level `AGENTS.md` files, and it’s easier to request a review from Copilot on draft pull requests with the Request button. These changes are all generally available.

You can now add an `AGENTS.md` file at the root of your repository to help shape Copilot code review feedback. If your repository already has an `AGENTS.md` file, Copilot code review will now utilize that context automatically as part of its workflow. This makes it easier to get reviews that better reflect your repository’s conventions and expectations.

You can already request Copilot code review on draft pull requests to get a first pass on your draft before even publishing your pull request. Now, the Request button shows up next to Copilot on draft pull requests. This makes that workflow easier by letting you request Copilot directly from the reviewer picker without needing to search for Copilot first.

On the Conversation tab of your pull request, Copilot code review events documented in the timeline can get noisy. We’ve collapsed certain Copilot code review timeline events together to help declutter your conversation tab, allowing you to find what matters, quickly.
