## 📦 Core Components

### 1. CLI Entry Point (`bin/zcode.js`)
- Command-line interface
- Options: `--dev`, `--no-bot`, `--no-cli`
- Version check and help

### 2. Orchestrator (`src/zcode.js`)
Initializes all components in order:
1. Environment validation
2. Configuration loading
3. API initialization
4. Tools loading
5. Skills loading
6. Agent loading
7. Bot initialization (optional)

### 3. Z.AI API Adapter (`src/api/index.js`)
- REST API client using Axios
- Streaming support
- Error handling
- Model management

### 4. Telegram Bot (`src/bot/index.js`)
- Express server for webhooks
- WebSocket for real-time updates
- Message processing
- Callback handling

### 5. Tools System (`src/tools/`)
- **BashTool**: Shell command execution
- **FileEditTool**: File operations with diff-aware editing
- **WebSearchTool**: Web search via DuckDuckGo API
- **GitTool**: Git operations (status, log, branch)

### 6. Skills System (`src/skills/index.js`)
- Load from JSON files
- Built-in skills: code_review, bug_fix, refactor, documentation, testing
- Categories: development, documentation, testing

### 7. Agents System (`src/agents/index.js`)
- **AgentOrchestrator**: Coordinates agent execution
- **Agents**:
  - Code Reviewer: Bug detection, security review
  - System Architect: Design patterns, architecture
  - DevOps Engineer: Deployment, CI/CD

### 8. Utilities (`src/utils/`)
- **Logger**: Winston-based logging
- **Env Check**: Environment variable validation

## 🔄 Message Flow

```
User (Telegram) → Webhook → Bot → Agent Processing
                                         ↓
                                    Tools Execution
                                         ↓
                                    Skills Application
                                         ↓
                                    Response Generation
                                         ↓
                                    User (Telegram)
```
