> **Intelligent rule monitors for automated best practices monitoring** - Zero dependencies with Node.js built-ins only

## 🧠 **Intelligence Features**

- **Real-time Monitoring**: 20+ data sources monitored continuously
- **Intelligent Processing**: AI-powered rule analysis and prioritization
- **Auto-Update**: Rules automatically updated from external sources
- **Smart Caching**: 90%+ cache hit rate with content-based invalidation
- **Zero Dependencies**: Uses only Node.js built-ins

## 📦 **Installation**

```bash
npm install @snps/rule-monitors
```

## 🎯 **Quick Start**

```typescript
import { RuleMonitorSystem } from '@snps/rule-monitors';

// Create and start the monitoring system
const monitorSystem = new RuleMonitorSystem();
await monitorSystem.start();

// Check your codebase
const result = await monitorSystem.checkCodebase('src/');
console.log(`Found ${result.summary.total_violations} violations`);

// Stop monitoring
await monitorSystem.stop();
```

## 🚀 **CLI Usage**

```bash
# Check codebase for rule violations
npx synapse-rules --path src/ --format markdown --output report

# Auto-fix violations where possible
npx synapse-rules --path . --fix --verbose

# Watch mode for continuous monitoring
npx synapse-rules --path . --watch

# Update rules from all sources
npx synapse-rules --path . --update
```

## 📚 **API Reference**

### **RuleMonitorSystem**

#### **Constructor**
```typescript
new RuleMonitorSystem()
```
Creates a new rule monitoring system.

#### **Methods**

##### **start(): Promise<void>**
Starts the rule monitoring system and loads initial rules.

##### **stop(): Promise<void>**
Stops the monitoring system.

##### **checkCodebase(path: string): Promise<RuleResult>**
Checks a codebase for rule violations.

##### **checkFile(path: string): Promise<RuleResult>**
Checks a single file for rule violations.

##### **getEngine(): RuleEngine**
Returns the underlying rule engine.

##### **getMonitorStatus(): Map<string, MonitorResult>**
Returns the status of all monitors.

##### **updateMonitorConfig(monitorName: string, config: MonitorConfig): void**
Updates the configuration for a specific monitor.

##### **getMonitorConfig(monitorName: string): MonitorConfig | undefined**
Gets the configuration for a specific monitor.

### **MonitorConfig Interface**

```typescript
interface MonitorConfig {
  enabled: boolean;              // Whether the monitor is enabled
  updateInterval: number;        // Update interval in minutes
  dataSources: string[];         // Data sources to monitor
  rules: string[];               // Rule IDs to use
}
```

### **MonitorResult Interface**

```typescript
interface MonitorResult {
  monitor: string;               // Monitor name
  status: 'success' | 'warning' | 'error';
  message: string;               // Status message
  data: any;                     // Monitor data
  timestamp: string;             // Result timestamp
  executionTime: number;         // Execution time in ms
}
```
