Recommends reviewers pull branch locally and run the app, require at least two approvals, keep PRs small (avoids 64 changed files, 3,000 lines), provide runnable code examples or a branch, enforce style with CI, and schedule a rotating maintenance week to pay down technical debt so “approve if better” doesn’t create hidden problems.
