# The VIBE Score: 8 Dimensions of Software Quality

A single quality number hides more than it reveals. The VIBE Score framework disaggregates software quality into eight measurable dimensions, each scored independently and weighted by risk impact. The result is a quality signal that is both comprehensive and actionable.

## The Eight Dimensions

### V — Velocity
How fast and reliably does the team ship? Deployment frequency, lead time for changes, CI/CD maturity, and feature flag usage.

### I — Intelligence
How well is AI integrated? Prompt injection prevention, output validation, model version pinning, and fallback strategies.

### B — Build Quality
How healthy is the codebase? Test coverage, type safety, dependency hygiene, and technical debt ratio.

### E — Experience
How good is the user experience? Core Web Vitals, WCAG accessibility, responsive design, and error recovery patterns.

### Security
How hardened is the attack surface? CSP headers, input validation, authentication patterns, and dependency vulnerabilities.

### Scalability
How ready is it for growth? Horizontal scaling, database optimization, CDN strategy, and cache architecture.

### Reliability
How resilient is it? Error budgets, monitoring coverage, alerting, disaster recovery, and graceful degradation.

### Maintainability
How sustainable is it long-term? Documentation coverage, onboarding time, modular architecture, and upgrade path clarity.

## Scoring Methodology

Each dimension is scored 0–100 using a combination of automated analysis and structured expert review. Dimensions are weighted by importance, with Security and Intelligence carrying higher weights due to the novel risks introduced by AI-generated code.
