Copilot expands reviews of agent-written pull requests. Keep the human checkpoint.

2026-08-28

Maestro’s take

Let an agent write the patch. Let another review it. Keep a person responsible for shipping it.

GitHub’s latest update makes that workflow easier. The useful question is not whether two AIs agree. It is whether the review catches a bug you would otherwise ship.

TL;DR

On August 27, GitHub expanded Copilot code review:

• Automatically requested reviews can cover bot-authored pull requests, with the required organization policy enabled.
• Pull requests from Copilot cloud agent can now receive full agentic review instead of the previous limited fallback.
• The old 300-file or 20,000-line size ceiling is gone.
• Review comments can be resolved as “Addressed,” “Won’t fix,” or “Incorrect.”

These are coverage changes, not evidence that every review is accurate. Read GitHub’s announcement.

Why Maestro users care

Picture a coding agent adding an invoice export to your portal. Its tests pass. A second review asks whether an ordinary user can export another customer’s invoices.

That is a useful challenge. “Looks good” from another model is not.

Our recommendation: treat the reviewer as someone who proposes things to test. Turn a credible finding into a failing test, fix the code, then rerun it. This example illustrates a workflow; it is not a result from testing the new release.

What does the extra check cost?

GitHub currently estimates $0.05–$1 of AI credits for a Lite review, or $0.25–$5 for Balanced. These are typical estimates, not fixed prices or caps. These estimates exclude GitHub Actions usage, which may add cost.

So 100 reviews at those estimated rates would consume roughly $5–$100 or $25–$500 of AI credits, before Actions. For licensed users, credits can come from an included or shared allowance rather than automatically becoming an extra charge.

The new path for bot reviews without a licensed account is different. It requires Copilot Business or Enterprise, paid AI-credit usage, and the policy allowing unlicensed code review. This is paid additional usage billed to the organization; an unlicensed user has no included review allowance. GitHub also warns that reviews can miss problems and that some file types are excluded. Review availability, billing, and limitations.

Try this on one repository

Do: enable automatic review on one test repository. Keep human review and your existing checks. Record useful bugs caught, false alarms, review time, and credit use.

Do not: enable repeated reviews on every agent push without checking the bill. GitHub lets you choose whether to review new pushes; without that option, the automatic review runs only once. Configuration guide.

Why: more review activity is not the same as better code. Keep the extra reviewer only if it earns its place.
