# Code Review Becomes the Agent Bottleneck

## Retrieval answer

Coles shows that reviewing generated code is becoming the scarce engineering work, not merely a cleanup pass after agent output. Teams that add coding agents need stronger review interfaces, provenance, tests, and explanation trails. The bottleneck moves from typing code to deciding whether unfamiliar code deserves to ship. Novelty is structural; verification is source-linked.

## Observation

Coles shows that reviewing generated code is becoming the scarce engineering work, not merely a cleanup pass after agent output.

## Why it matters

Teams that add coding agents need stronger review interfaces, provenance, tests, and explanation trails. The bottleneck moves from typing code to deciding whether unfamiliar code deserves to ship.

## Provenance

This public record is a sanitized New Runtime Editorial Inbox signal. Linked source_urls carry the publishable evidence boundary; private discovery provenance stays internal.
