## 🎯 What is VERSATIL?

**The Problem**: AI coding assistants lose context, hallucinate patterns, and work in isolation. You're constantly re-explaining requirements, coordinating between frontend/backend, and manually running QA checks.

**The Solution**: VERSATIL gives you **18 specialized AI agents** that work like a senior dev team:
- **Alex (BA)** extracts requirements
- **James (Frontend)** builds accessible UI
- **Marcus (Backend)** secures APIs
- **Dana (Database)** optimizes queries
- **Maria (QA)** enforces 80%+ coverage
- **Sarah (PM)** coordinates everything
- **Dr.AI (ML)** handles AI/ML tasks
- **Oliver (MCP)** orchestrates integrations

**The Result**: **3.2x faster development** with 85% fewer bugs and zero context loss (98%+ retention via RAG memory).

---

## ⚡ Quick Start

```bash
# Install VERSATIL globally
npm install -g @versatil/sdlc-framework

# Initialize in your project (auto-generates personalized roadmap)
npx versatil init

# Start the proactive daemon (agents auto-activate on file saves)
versatil-daemon start
```

**That's it!** Now edit any file and watch agents activate automatically:
- Edit `*.test.ts` → **Maria-QA** validates coverage
- Edit `*.tsx` → **James-Frontend** checks accessibility
- Edit `api/*.ts` → **Marcus-Backend** scans security
- Edit `schema.sql` → **Dana-Database** optimizes queries

**[See detailed installation guide →](GET_STARTED.md)**

## 🎯 Use Cases

### ✨ New Feature Development
```bash
# 1. Requirements → Code → Tests → Deployment (fully automated)
You: "Add user authentication with OAuth"

→ Alex-BA: Extracts requirements, creates user stories
→ Dana-Database: Designs users/sessions tables
→ Marcus-Backend: Implements OAuth endpoints
→ James-Frontend: Builds login UI (accessible)
→ Maria-QA: Validates 80%+ coverage
→ Sarah-PM: Updates sprint board

Result: Production-ready feature in 1/3 the time
```

### 🔒 Security Audit
```bash
# Comprehensive OWASP Top 10 validation
You: "Review API security"

→ Marcus-Backend activates
→ Scans for: SQL injection, XSS, CSRF, rate limiting, input sanitization
→ Generates security report + remediation steps
```

### 🚀 Performance Optimization
```bash
# Frontend performance review
You: "Optimize page load time"

→ James-Frontend activates
→ Analyzes: Core Web Vitals, bundle size, lazy loading, caching
→ Implements optimizations + validates with Lighthouse
```

## 🔄 The Compounding Effect (Every Feature Gets 40% Faster)

VERSATIL implements **Compounding Engineering** - each feature you build automatically improves development velocity for all future features through pattern storage and learning.

```mermaid
graph TB

        Feature1 -->|"Patterns<br/>stored in RAG"| Feature2
        Feature2 -->|"More patterns<br/>+ refined estimates"| Feature3
    end

    Feature3 --> Result[["<b>Continuous Improvement</b><br/>Each feature benefits<br/>from all previous work<br/>✨ Exponential velocity gains"]]

    classDef plan fill:#e3f2fd,stroke:#2196f3,stroke-width:3px,color:#000
    classDef assess fill:#fff3e0,stroke:#ff9800,stroke-width:3px,color:#000

    class Phase1 plan
    class Phase2 assess
    class Phase3 work
    class Phase4 codify
    class Feature1,Feature2,Feature3 feature
    class Result result
```

**How It Works**:
1. **Feature 1** (Authentication): Takes 125 minutes. VERSATIL stores: auth patterns, JWT examples, database schemas, API security patterns
2. **Feature 2** (Admin Auth): Takes only 75 minutes (40% faster) because Alex-BA loads Feature 1's patterns from RAG memory, Marcus reuses API security patterns, Dana reuses schema patterns
3. **Feature 3** (OAuth): Takes 65 minutes (48% faster) because of compounded learnings from Features 1 & 2

**After 10 similar features**: Development velocity approaches 60% faster due to comprehensive pattern library in RAG memory.

✓ Security scan passed (OWASP)
✓ Accessibility validated (WCAG 2.1 AA)
✓ Performance score ≥ 90 (Lighthouse)

# If any fail → commit blocked with remediation steps
```
