Engineering
Agents that read each diff, flag bugs and risky changes, check style and leave review comments before a human looks.
26 published use cases
Copilot and Claude review each PR for bugs, missing tests and risky changes before a human looks, so reviewers can focus on design.
Pair two coding agents so one writes a change and the other reviews it, iterating until approval or a round limit.

Original post ↗Not entirely. AI reviewers are good at catching obvious bugs, missing tests and style issues on every pull request, which frees human reviewers to focus on design and intent. Most teams keep a human approval as the merge gate.
