# Context Crystallizer 💎

**AI Context Engineering for Large Repositories**

Transform massive repositories into crystallized, AI-consumable knowledge through systematic analysis and optimization.

## What is Crystallization?

Just as pressure transforms carbon into diamonds, Context Crystallizer applies systematic AI analysis to transform raw repositories into **crystallized knowledge** - structured, searchable, and optimized for AI consumption. Each file is analyzed to extract its purpose, key APIs, patterns, and relationships, creating a knowledge base that AI can efficiently search and understand.

## Inspiration

Context Crystallizer was inspired by [AI Distiller (aid)](https://github.com/janreges/ai-distiller), which pioneered the concept of intelligently extracting essential information from large codebases for AI consumption. While AI Distiller focuses on extracting public APIs and type information using tree-sitter parsers, Context Crystallizer takes a complementary approach by having AI agents generate comprehensive crystallized contexts about functionality, patterns, and relationships.

## The Problem 🔥

AI agents hit context length limits when working with large repositories. A typical enterprise repository has 10,000+ files, but LLMs can only process a fraction at once. This forces AI to work blindly or make assumptions about unfamiliar code.

## The Solution ✨

Context Crystallizer creates a **searchable crystallized context base** of AI-optimized knowledge:

- 🔍 **Search by functionality**: "find authentication middleware" 
- ⚡ **Token-efficient**: 5:1 compression ratio (source:crystallized context)
- 🤖 **AI-optimized format**: Structured specifically for LLM consumption
- 📊 **Smart assembly**: Combines multiple contexts within token limits
- 💎 **Crystallized knowledge**: Preserves essential information in optimized form

## How It Works

**Simple 3-step crystallization process:**

1. **Initialize**: Scan repository and prepare for crystallization
   - Automatically respects `.gitignore` patterns
   - Skips common build directories (node_modules, dist, build, .git)
   - Filters out binary files and very large files (>1MB)
2. **Crystallize**: AI analyzes each file to extract meaningful knowledge  
3. **Search**: Find relevant crystallized contexts for any task

## Quick Demo

**Developer using Claude Code with a large documentation repository:**

> **Developer**: "I need to understand how authentication works in this massive project"
>
> **Claude**: "I'll crystallize this repository first to build a searchable knowledge base, then find all authentication-related information."
>
> *Claude crystallizes the repository - scanning and analyzing each file*
>
> **Claude**: "Crystallization complete! I found 5 files with authentication logic. The main JWT middleware handles token validation with Redis session caching. Here's how it works..."
>
> *Claude provides comprehensive explanation using crystallized contexts*
>
> **Developer**: "What files depend on the authentication system?"
>
> **Claude**: "Let me search for related crystallized contexts..."
>
> *Claude uses find_related_crystallized_contexts() to discover dependencies*

## Installation & Setup

### Quick Start (5 minutes)

```bash
# Install globally via NPM
npm install -g context-crystallizer

# Navigate to your project
cd /path/to/your/project

# Start the MCP server
context-crystallizer
```

### Claude Desktop Integration

Add to your Claude Desktop configuration (`~/claude_desktop_config.json`):

```json
{
  "mcpServers": {
    "context-crystallizer": {
      "command": "npx",
      "args": ["context-crystallizer"],
      "cwd": "/path/to/your/project"
    }
  }
}
```

## Context Crystallizer Tools

Context Crystallizer provides dual access to crystallization functionality: AI agents can use MCP tools for conversation-driven analysis, while developers can use CLI commands for direct control.

### AI Agent Usage (MCP Tools)

AI agents interact with Context Crystallizer through MCP (Model Context Protocol) for conversation-driven crystallization and knowledge search.

| **search_crystallized_contexts** | Find relevant knowledge by functionality | **Developer**: "How does authentication work in this app?" **Claude**: "Let me search the crystallized contexts..." *Claude calls search_crystallized_contexts with query="authentication"* **Claude**: "Found 5 auth-related files: JWT middleware, login component, auth context..." |
| **get_crystallized_bundle** | Combine multiple contexts | **Developer**: "Show me how the payment system works" **Claude**: "I'll bundle all payment-related contexts..." *Claude calls get_crystallized_bundle* **Claude**: "The payment flow involves 4 components: PaymentForm, Stripe integration, order processing..." |
| **find_related_crystallized_contexts** | Discover code relationships | **Developer**: "What depends on this Auth.tsx file?" **Claude**: "Let me find related contexts..." *Claude calls find_related_crystallized_contexts* **Claude**: "Found 3 related files: LoginPage uses Auth.tsx, ProtectedRoute depends on it..." |
| **search_by_complexity** | Find contexts by difficulty level | **Developer**: "Show me simple files to understand first" **Claude**: "Finding low-complexity files..." *Claude calls search_by_complexity with complexity="low"* **Claude**: "Here are 8 simple config files and utility functions to start with..." |
