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:

   cd claude-hooks
   ./scripts/install.sh
   

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

3. Test:

   ./scripts/test.sh
   

🎯 Features in Action

Command Validation

$ 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

🔧 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!
