How to Build a Contributor Leaderboard Based on Code Quality

Engineering metrics are traditionally focused on velocity: How many commits? How many PRs merged? How fast did we close tickets?

In the era of AI coding, velocity metrics are utterly meaningless. A junior developer with Cursor can generate 10,000 lines of code in a week. If you reward velocity, you will drown in technical debt.

You must shift the culture to reward *quality*.

## The VibeFix Leaderboard

VibeFix introduces a new metric to gamify software development: **The Average Vibe Score.**

Our built-in Leaderboard feature allows engineering managers (or open-source maintainers) to rank contributors not by the volume of code they push, but by the *cleanliness* and *sustainability* of their commits.

## How It Works

1. **Data Aggregation:** Every time a PR is merged, VibeFix calculates the Vibe Score of that specific contribution and attributes it to the developer.

2. **The Ranking:** The Leaderboard displays a rolling average of a developer's last 20 PRs. This smooths out anomalies and shows their true baseline quality.

3. **The Delta Hero:** The dashboard also prominently highlights developers who consistently submit PRs with a *positive Quality Delta* (meaning they are actively cleaning up the repo, not just adding to it).

## Why Gamification Works

Developers are inherently competitive problem solvers. When you put a number next to their name, they will work to optimize it.

By installing the VibeFix Leaderboard, you subtly shift the developer mindset from "How fast can I get this PR approved?" to "How can I refactor this AI output to get my score above a 90?"
