# Quality How much to trust AI-generated code, and the review habits that catch what a fast agent misses. Source: https://codeherder.com/blog/topics/quality/ Topic Fast code is not the same as safe code. Here is how we keep both. Quality covers the review and verification steps between an agent's first draft and a merged change. It answers what a reviewer should check, and what a test suite should cover. It also shows where a written rubric beats a gut feeling. An agent can produce working code quickly and still get the wrong thing done well. The fix is not to slow every task down. Put a real gate where it catches the failure: tests, a second agent's review, a human check on the risky parts. Skip the gate where it only adds delay. This hub is for anyone deciding how much to trust a merge an agent proposed. It covers the checks that earn that trust, without turning review into a bottleneck.

A practical guide to reviewing agent work at scale](https://codeherder.com/blog/trusting-ai-generated-code/) The real question isn't whether AI agents can write code.
