PR Size Guard - GitHub Pull Request Reviewer

About

📏 PR Size Guard — See Pull Request Size at a Glance

Tired of opening a GitHub Pull Request only to discover it has 2,000+ lines of changes? PR Size Guard shows you the PR size instantly with a color-coded badge.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

🎯 WHAT IT DOES

When you open any Pull Request on GitHub, PR Size Guard automatically:
• Detects the number of files changed
• Counts lines added and deleted
• Displays a badge: Small, Medium, Large, or Critical

The badge appears right next to the PR title — no clicks needed.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

🚦 SIZE CATEGORIES

🟢 Small — Quick review (≤5 files, ≤100 lines)
🟠 Medium — Normal review (≤15 files, ≤400 lines)
🔴 Large — Needs focus (≤30 files, ≤1000 lines)
⛔ Critical — Consider splitting (>30 files or >1000 lines)

💡 WHY PR SIZE MATTERS

Studies show code review quality drops significantly after ~400 lines. Large PRs:
• Take longer to review
• Hide bugs more easily
• Cause reviewer fatigue
• Delay shipping

PR Size Guard helps you identify these PRs before you start reviewing.
