# Comprehensive Codebase Analysis

## Project Discovery Phase

### File Count and Size Analysis
- Total files: !`find . -type f -not -path "./node_modules/*" -not -path "./.git/*" | wc -l`
- Code files: !`find . -name "*.js" -o -name "*.ts" -o -name "*.jsx" -o -name "*.tsx" -o -name "*.py" -o -name "*.java" -o -name "*.php" -o -name "*.rb" -o -name "*.go" -o -name "*.rs" -o -name "*.cpp" -o -name "*.c" | grep -v node_modules | wc -l`
- Project size: !`find . -type f -not -path "./node_modules/*" -not -path "./.git/*" -not -path "./dist/*" -not -path "./build/*" -not -path "./.next/*" -not -path "./coverage/*" -exec du -ch {} + 2>/dev/null | grep total$ | cut -f1`

## Source Code Analysis

### Main Application Files

## Key Files Content Analysis

### Root Configuration Files
@README.md
@LICENSE
@.gitignore

### Main Application Entry Points
!`find . -name "index.js" -o -name "index.ts" -o -name "main.js" -o -name "main.ts" -o -name "app.js" -o -name "app.ts" -o -name "server.js" -o -name "server.ts" 2>/dev/null | grep -v node_modules | head -5 | while read file; do echo "=== $file ==="; head -50 "$file" 2>/dev/null || echo "Could not read $file"; echo; done || echo "No main entry point files found"`

## Your Task

Based on all the discovered information above, create a comprehensive analysis that includes:

## 1. Project Overview
- Project type (web app, API, library, etc.)
- Tech stack and frameworks
- Architecture pattern (MVC, microservices, etc.)
- Language(s) and versions

## 2. Detailed Directory Structure Analysis
For each major directory, explain:
- Purpose and role in the application
- Key files and their functions
- How it connects to other parts

## 3. File-by-File Breakdown
Organize by category:
- **Core Application Files**: Main entry points, routing, business logic
- **Configuration Files**: Build tools, environment, deployment
- **Data Layer**: Models, database connections, migrations
- **Frontend/UI**: Components, pages, styles, assets  
- **Testing**: Test files, mocks, fixtures
- **Documentation**: README, API docs, guides
- **DevOps**: CI/CD, Docker, deployment scripts

## 4. API Endpoints Analysis
If applicable, document:
- All discovered endpoints and their methods
- Authentication/authorization patterns
- Request/response formats
- API versioning strategy

## 5. Architecture Deep Dive
Explain:
- Overall application architecture
- Data flow and request lifecycle
- Key design patterns used
- Dependencies between modules

## 6. Environment & Setup Analysis
Document:
- Required environment variables
- Installation and setup process
- Development workflow
- Production deployment strategy

## 7. Technology Stack Breakdown
List and explain:
- Runtime environment
- Frameworks and libraries
- Database technologies
- Build tools and bundlers
- Testing frameworks
- Deployment technologies

## 8. Visual Architecture Diagram
Create a comprehensive diagram showing:
- High-level system architecture
- Component relationships
- Data flow
- External integrations
- File structure hierarchy

Use ASCII art, mermaid syntax, or detailed text representation to show:
┌─────────────────┐     ┌─────────────────┐     ┌─────────────────┐
│     Frontend    │────▶│      API        │────▶│    Database     │
│   (React/Vue)   │     │   (Node/Flask)  │     │ (Postgres/Mongo)│
└─────────────────┘     └─────────────────┘     └─────────────────┘

## 9. Key Insights & Recommendations
Provide:
- Code quality assessment
- Potential improvements
- Security considerations
- Performance optimization opportunities
- Maintainability suggestions

Think deeply about the codebase structure and provide comprehensive insights that would be valuable for new developers joining the project or for architectural decision-making.

At the end, write all of the output into a file called "codebase_analysis.md"
