Smaller PRs, Faster Shipping: The 200-Line Habit

Big refactors feel productive. They also create slower reviews, more conflicts, and higher risk. We learned that the fastest teams aren't just fast at coding. They're fast at reviewing.

Why Size Matters

Reviewers have limited context. When a PR changes too many files at once, it becomes hard to spot subtle issues. Smaller PRs reduce cognitive load and make it easier to reason about impact.

The 200-Line Habit

We aim to keep most PRs around 200 lines of meaningful change. That's not a hard rule, but it's a useful forcing function. If a PR starts to balloon, we split it into slices that still add value independently.

How We Keep PRs Small

• Feature flags: Ship partial functionality safely without blocking the release train.
• Stacked PRs: Layer changes so reviewers only focus on what changed in each step.
• Scope guards: We pause and split when a PR starts mixing unrelated concerns.

Small PRs are kinder to reviewers and kinder to production. They keep feedback tight, make rollbacks easier, and help teams ship consistently.
