+# Claude Code → Del Port Implementation Plan
+
+## Executive Summary
+
+This document outlines a comprehensive plan to port Claude Code's functionality to Del, replacing Anthropic's Claude API with Ollama for local AI model execution. Del will maintain full compatibility with Claude Code's interface while offering local processing capabilities.
+
+## Analysis Phase Results
+
+### Claude Code Architecture Overview
+
+Based on analysis of the deobfuscated source (`cli.js` - 345K lines) and package structure:
+
+**Core Components:**
+- **CLI Interface**: Node.js-based terminal application (`claude` command)
+- **SDK Module**: `sdk.mjs` with TypeScript definitions for programmatic access
+- **OAuth Authentication**: Full OAuth2 flow with Anthropic Console integration
+- **Streaming Communication**: WebSocket-based real-time responses
+- **Tool System**: Extensive tool calling framework
+- **Image Processing**: Sharp integration for image handling
+
+**Key API Endpoints Discovered:**
+```
+Base API: https://api.anthropic.com
+OAuth Authorize: https://console.anthropic.com/oauth/authorize
+Token: https://console.anthropic.com/v1/oauth/token
+API Key Creation: https://api.anthropic.com/api/oauth/claude_cli/create_api_key
+Roles: https://api.anthropic.com/api/oauth/claude_cli/roles
+```
+
+**Authentication Flow:**
+- OAuth2 with scopes: `org:create_api_key`, `user:profile`, `user:inference`
+- Client ID: `9d1c250a-e61b-44d9-88ed-5944d1962f5e`
+- Local redirect server on port 54545
+
+## Implementation Roadmap
+
+### Phase 1: Foundation Architecture (Week 1-2)
+
+#### 1.1 Core Framework
+- **Status**: ⚡ **PARTIALLY COMPLETE**
+- **Current State**: Del has basic CLI, streaming, and tool execution
+- **Remaining Work**:

+ - [ ] Add SDK module (`del-sdk.mjs`) for programmatic access
+ - [ ] Create TypeScript definitions
+
+#### 1.2 Enhanced Tool System
+- **Status**: 🔄 **IN PROGRESS**
+- **Current State**: 7 basic tools implemented (read_file, list_dir, run_command, git_status, write_file, analyze_code, search_code)
+- **Missing Tools to Add**:
+ - [ ] File operations: copy, move, delete, chmod
+ - [ ] Advanced Git operations: commit, push, pull, branch, merge
+ - [ ] Project analysis: dependency scan, test runner detection
+ - [ ] Code refactoring: rename, extract function, format
+ - [ ] Database operations: query, schema analysis
+ - [ ] Web scraping: fetch URLs, parse HTML
