# Tool List > Claude Code CLI Source Code Analysis Project ## Project Introduction This is the source code of the official Anthropic **Claude Code CLI** tool for learning, research, and analysis purposes. Claude Code is a powerful AI programming assistant command-line tool that supports automation of various programming tasks. ## Technology Stack | Category | Technology | |------|------| | **Language** | TypeScript / TSX | | **Runtime** | Bun | | **UI Framework** | Ink (React for CLI) | | **Package Manager** | Bun | | **CLI Framework** | Commander.js | | **Terminal Style** | Chalk | ## Project Structure ``` src/ ├── commands/ # Command implementations (/commit, /review, etc.) ├── components/ # UI components (based on Ink React) │ └── design-system/ # Design system components ├── services/ # Core services │ ├── api/ # API services │ ├── mcp/ # MCP protocol implementation │ ├── analytics/ # Analytics services │ └── settingsSync/ # Settings synchronization ├── tools/ # Tool implementations │ ├── BashTool/ # Shell command execution │ ├── FileReadTool/ # File reading │ ├── FileEditTool/ # File editing │ ├── GrepTool/ # Code search │ ├── GlobTool/ # File matching │ ├── TaskTool/ # Task agent │ └── ... # More tools ├── hooks/ # React Hooks ├── constants/ # Constant definitions ├── ink/ # Terminal UI framework ├── utils/ # Utility functions ├── schemas/ # JSON Schema definitions ├── screens/ # Screen components ├── plugins/ # Plugin system ├── keybindings/ # Shortcut key bindings └── main.tsx # Main entry file ``` ## Core Features ### Command List #### Git & Code Management | Command | Description | |------|------| | `/commit` | Intelligent Git commit generation | | `/review` | Code review | | `/pr_comments` | PR comment analysis | | `/diff` | Difference viewing | | `/branch` | Branch management | #### Session Management | Command | Description | |------|------| | `/resume` | Resume historical sessions | | `/session` | Session management | | `/clear` | Clear conversation | | `/compact` | Compress context | | `/rewind` | Rewind operation | | `/export` | Export session | #### Configuration & Settings | Command | Description | |------|------| | `/config` | Configuration management | | `/init` | Initialize project | | `/model` | Switch model | | `/theme` | Theme settings | | `/login` | Login account | | `/logout` | Logout account | #### MCP & Plugins | Command | Description | |------|------| | `/mcp` | MCP server management | | `/plugin` | Plugin management | | `/skills` | Skill system | #### Tools & Diagnostics | Command | Description | |------|------| | `/doctor` | System diagnosis | | `/cost` | Cost statistics | | `/usage` | Usage statistics | | `/help` | Help information | | `/upgrade` | Upgrade version | #### Mode Switching | Command | Description | |------|------| | `/vim` | Vim mode | | `/plan` | Plan mode | | `/fast` | Fast mode | | `/permissions` | Permission management | | `/hooks` | Hook configuration | ## Architecture Highlights ### 1. Tool System (Tools) Each tool is an independent module, including: - Input validation (JSON Schema) - Execution logic - Permission control - Output formatting ### 2. Command System (Commands) Supports multiple command types: - `prompt` - Prompt command - `local` - Local execution command - `dialog` - Dialog command ### 3. MCP Protocol Complete Model Context Protocol implementation, supporting: - Stdio transmission - SSE transmission - Resource management - Tool invocation ### 4. Skill System (Skills) Extensible skill framework: - Built-in skills - Plugin skills - Custom skill directory ### 5. Agent System (Agents) Multi-agent collaboration support: - Task agent - Parallel execution - Context isolation ## Code Statistics | Indicator | Quantity | |------|------| | TypeScript files | ~1884 | | Command quantity | ~50+ | | Tool quantity | ~30+ | | UI components | ~100+ | ## Key Files | File | Description | |------|------| | `main.tsx` | Application main entry | | `commands.ts` | Command registration center | | `tools.ts` | Tool registration center | | `context.ts` | Context management | | `ink.tsx` | UI rendering engine | ## Dependency Relationship ``` main.tsx ├── commands.ts ──► commands/ ├── tools.ts ──► tools/ ├── services/ │ ├── api/ │ ├── mcp/ │ └── analytics/ └── components/ └── design-system/ ``` ## Learning Value 1. **CLI Application Architecture** - Large command-line tool design patterns 2. **React Terminal UI** - Ink framework practical application 3. **MCP Protocol** - AI tool interconnection protocol implementation 4. **Plugin System** - Extensible architecture design 5. **Agent System** - Multi-agent collaboration mode ## Disclaimer This project is for learning and research purposes only.
