Code Review Breaks in the Agent Era: Redesign for Human-Agent-Agent-Human
gabe_ragland · x · 2026-10-19
A developer essay argues code review has gotten worse—not because it lacks value, but because its collaborative and learning functions erode in human-agent workflows.
- Implementer side: When agents write most of the code, reviewers only see the output, not the human's thinking. Generated code no longer carries signals like naming choices, abstractions, or shortcuts. The author suggests hand-writing PR descriptions or doing explicit self-reviews that flag which parts were thought hard about.
- Reviewer side: Reviewing feels lonely and less educational; the process was built for human-to-human interaction and needs redesigning for human-agent-agent-human flows.
Core thesis: the problem is systemic—processes must be rebuilt for the new collaboration shape, not blamed on individuals.
