# 🔍 Claude Code Implementation Audit Report

## Critical Issues Found

### ❌ **Missing Tools** (Major Gap)
Our implementation is missing several core Claude Code tools:

1. **NotebookRead** - Read Jupyter notebooks with cell structure
2. **NotebookEdit** - Edit specific notebook cells with insert/delete/replace modes  
3. **WebFetch** - Fetch and process web content with AI analysis
4. **WebSearch** - Search web with query processing
5. **Task/Agent** - Complex task orchestration and multi-step workflow execution
6. **exit_plan_mode** - Workflow management for planning mode

### ❌ **Tool Algorithm Issues**

#### 1. **Read Tool** - Incorrect Format
- **Current**: Uses `{i:6d}→{line}` 
- **Required**: Should use exact `cat -n` format with proper spacing
- **Missing**: File size limits (50MB default), proper binary detection

#### 2. **Edit Tool** - Missing Validation
- **Missing**: Must read file first before editing (validation requirement)
- **Missing**: Proper atomic operation guarantees
- **Missing**: Path normalization and security validation

#### 3. **Bash Tool** - Incomplete Security
- **Missing**: Comprehensive dangerous command patterns
- **Missing**: Interactive command blocking
- **Missing**: Proper working directory management

#### 4. **LS Tool** - Wrong Output Format
- **Current**: Basic emoji format
- **Required**: Specific file size formatting, proper directory indicators
- **Missing**: Default ignore patterns (`.git`, `__pycache__`, etc.)

#### 5. **Glob/Grep Tools** - Performance Issues
- **Missing**: Proper sorting by modification time
- **Missing**: Large codebase optimization
- **Missing**: Binary file filtering for grep

### ❌ **System Integration Issues**

#### 1. **Tool Calling Mechanism**
- **Issue**: Our tool calling doesn't match Claude Code's exact protocol
- **Missing**: Proper tool result formatting and streaming integration
- **Missing**: Tool execution error handling that matches Claude Code

#### 2. **CLI Interface**
- **Missing**: Exact prompt format (`> ` instead of custom HTML)
- **Missing**: Proper streaming response display that matches Claude Code
- **Missing**: Plan mode and workflow management

#### 3. **System Prompts**
- **Issue**: Our system prompts are generic, not Claude Code specific
- **Missing**: Exact instructions and behavior patterns
- **Missing**: Proper tool usage guidelines

### ❌ **Interactive Features**
- **Missing**: Proper plan mode with exit_plan_mode tool
- **Missing**: File watching capabilities
- **Missing**: Git integration helpers
- **Missing**: Image reading for screenshots
- **Missing**: Advanced markdown rendering

## 📊 Completeness Score: 60%

- ✅ Basic file operations (partial)
- ✅ Command execution (basic)
- ✅ CLI framework
- ❌ Missing 6 major tools
- ❌ Incorrect algorithms for existing tools
- ❌ Missing advanced features
- ❌ System integration issues

## 🚨 Immediate Action Required

1. **Add Missing Tools** - Implement all missing Claude Code tools
2. **Fix Tool Algorithms** - Correct each tool to match exact specifications
3. **Update System Prompts** - Use exact Claude Code prompts and behavior
4. **Fix CLI Interface** - Match exact Claude Code user experience
5. **Add Missing Features** - Plan mode, workflows, advanced integrations

## Recommendation

**Complete rewrite required** to match Claude Code exactly. Current implementation is a basic prototype but lacks 40% of functionality and has incorrect implementations.
