# Claude Code Hooks Demo

## What We Built

A complete, production-ready hooks system for Claude Code with:

## 🧠 Intelligent Features
- **Shadow Learner**: Learns from your command patterns and prevents repeated failures
- **Context Monitor**: Automatically backs up your work before hitting context limits
- **Session Continuity**: Seamlessly restore context across Claude sessions
- **Smart Validation**: Blocks dangerous commands and suggests alternatives

## 🚀 Quick Start

1. **Install:**
   ```bash
   cd claude-hooks
   ./scripts/install.sh
   ```

2. **Configure Claude Code:**
   The installer will automatically add the hooks configuration to your Claude settings.

3. **Test:**
   ```bash
   ./scripts/test.sh
   ```

## 🎯 Features in Action

### Command Validation
```bash
$ pip install requests
# ⛔ Blocked: pip commands often fail (confidence: 95%)
# 💡 Suggestion: Use "pip3 install requests"
```

### Context Monitoring
```
Auto-backup created: context_threshold (usage: 87%)
```

### Session Continuity
- `LAST_SESSION.md` - Complete session summary
- `ACTIVE_TODOS.md` - Persistent task tracking
- `RECOVERY_GUIDE.md` - Step-by-step restoration

### Shadow Learning
The system learns from every interaction:
- Failed commands → Suggests alternatives
- Successful patterns → Recognizes workflows
- Error contexts → Provides relevant warnings

## 🛡️ Safety & Security

- **Fail-Safe Design**: Never blocks Claude's core functionality
- **Command Injection Protection**: Blocks malicious command patterns
- **Path Traversal Prevention**: Protects system files
- **Data Sanitization**: Removes secrets from logs
- **Resource Limits**: Prevents DoS attacks

## 📊 Monitoring & Management

```bash
# Check system status
claude-hooks status

# View learned patterns
claude-hooks patterns

# List backups
claude-hooks list-backups

# Export all data
claude-hooks export
```

## 🔧 Architecture Highlights

- **Event-Driven**: Uses Claude Code's native hook points
- **Resilient**: Comprehensive error handling and fallbacks
- **Performance-Optimized**: Caching, rate limiting, async operations
- **Extensible**: Clean interfaces for adding new features

## 💪 Edge Cases Handled

- Hook script crashes → Fail-safe defaults
- Git repository issues → Filesystem fallbacks  
- Network storage failures → Local cache
- Database corruption → Multiple recovery levels
- Resource exhaustion → Automatic cleanup
- Concurrent sessions → Process isolation

## 🎉 What Makes This Special

1. **Learning System**: Gets smarter with every use
2. **Zero Downtime**: Never interrupts your workflow
3. **Context Preservation**: Never lose work to context limits
4. **Intelligent Validation**: Prevents issues before they happen
5. **Complete Solution**: Production-ready out of the box

This is a sophisticated, enterprise-grade system that transforms Claude Code into an intelligent, self-improving development assistant!
