Repository Health Score

Score a repository's health across 8 dimensions — code quality, testing, documentation, CI/CD, security, dependencies, community, and maintainability. Produces a letter grade (A-F) with specific improvement suggestions.

Repository Health Score

Rate any repository on a 0-100 scale across 8 dimensions. Like a credit score for code — quick assessment of project maturity, maintenance quality, and risk level.

Use when: "how healthy is this repo", "rate this codebase", "project quality audit", "is this repo well-maintained", "should we adopt this library", "repository assessment", or during due diligence on open-source dependencies.

Commands

1. `score` — Full Health Assessment

Composite Score

Sum all dimensions (max 100) and assign a letter grade:

Score	Grade	Assessment
90-100	A	Excellent — production-ready, well-maintained
80-89	B	Good — solid project with minor gaps
70-79	C	Fair — functional but needs attention
60-69	D	Below average — significant gaps
<60	F	Poor — high risk, needs major investment

2. `compare` — Compare Two Repositories

Run score on two repos and produce a side-by-side comparison. Useful for choosing between competing libraries.

3. `improve` — Top 5 Improvements

Based on the score breakdown, suggest the 5 highest-impact improvements with AI reasoning:

markdown

## Top 5 Improvements (by score impact)

1. **Add tests** (+8 points) — No test files found. Start with unit tests for core modules.
   Effort: M | Impact: Testing 0→8/15

2. **Configure CI** (+6 points) — No CI pipeline. Add GitHub Actions with lint+test+build.
   Effort: S | Impact: CI/CD 0→6/12

3. **Add CHANGELOG.md** (+2 points) — No changelog. Start with Keep a Changelog format.
   Effort: XS | Impact: Documentation 11→13/15

4. **Set up Dependabot** (+2 points) — No dependency automation.
   Effort: XS | Impact: Security 8→10/12

5. **Add CONTRIBUTING.md** (+3 points) — No contributor guide.
   Effort: S | Impact: Community 4→7/12

Output Formats

text (default): Human-readable scorecard with bar chart
json: {total, grade, dimensions: {name: {score, max, details: []}}, improvements: []}
markdown: Report card format with tables and grade badges
badge: Shield.io badge URL for README: ![Health Score](https://img.shields.io/badge/health-B%2083%25-green)

Notes

Works on any git repository — adapts to language/framework automatically
Does not execute code or install dependencies — purely static analysis
Community dimension requires gh CLI for GitHub metrics (optional)
Scores are relative — a CLI tool and a web app have different baselines
Run periodically to track improvement trends
