Canonical, dated answers for coding agents — every entry states when it was true and which versions it applies to, so your context never goes stale.
Agents write plausible code fast. Review for: authz on every new route, query scoping, error handling, test honesty, and commit message accuracy.
Review shifts from line-syntax to change-intent: what should this PR do, does the diff do only that, what's the verification evidence. Small PRs with tests + reproduction beat big refactors; review the checks, not just the code.
