## Features Implemented

### Commands (5 total)

1. **AI-BOM: Scan Workspace** - Scan entire workspace for AI components
2. **AI-BOM: Scan Current File** - Scan only the active file
3. **AI-BOM: Show Results** - Open the AI-BOM sidebar
4. **AI-BOM: Clear Results** - Clear all scan results
5. **AI-BOM: Install Scanner** - Install/reinstall ai-bom CLI

### UI Components (4 major areas)

1. **Sidebar Views**
   - Scan Results panel (organized by severity: Critical > High > Medium > Low)
   - Summary panel (statistics, duration, timestamp)
   - Click to navigate to code locations

2. **Problems Panel Integration**
   - AI components appear as diagnostics
   - Severity mapping (Critical=Error, High=Warning, etc.)
   - Related information with risk factors and flags
   - OWASP category mapping

3. **Inline Editor Decorations**
   - Gutter icons (error/warning/info icons by severity)
   - Inline risk score annotations (e.g., "Risk: 75")
   - Hover tooltips with component details
   - Colored line highlights

4. **Status Bar**
   - Quick scan summary (e.g., "AI-BOM: 3 critical")
   - Click to open sidebar
   - Updates on scan completion

### Configuration Settings (6 settings)

| Setting | Type | Default | Description |
|---------|------|---------|-------------|
| `ai-bom.pythonPath` | string | `python3` | Path to Python interpreter |
| `ai-bom.scanOnSave` | boolean | `false` | Auto-scan files on save |
| `ai-bom.severityThreshold` | enum | `low` | Minimum severity to display |
| `ai-bom.deepScan` | boolean | `false` | Enable AST-based analysis |
| `ai-bom.showInlineDecorations` | boolean | `true` | Show inline risk annotations |
| `ai-bom.autoInstall` | boolean | `false` | Auto-install ai-bom if missing |

### Context Menus (2 locations)

- Explorer context menu (right-click file)
- Editor context menu (right-click in editor)

## Technical Architecture

### Technology Stack

- **Language**: TypeScript 5.3+ (strict mode)
- **Target**: VS Code Extension API 1.85.0+
- **Runtime**: Node.js (via VS Code)
- **Scanner**: ai-bom Python CLI (subprocess)
- **Build**: TypeScript compiler (tsc)
- **Lint**: ESLint with TypeScript plugin
- **Package**: vsce (VS Code Extension Manager)

### Design Patterns

1. **Singleton Pattern**: Extension activates once, maintains state
2. **Observer Pattern**: Tree views update on scan completion
3. **Command Pattern**: All user actions as registered commands
4. **Provider Pattern**: Tree data providers for views
5. **Decorator Pattern**: Editor decorations for inline display

### Data Flow

```
User Command
    ↓
Extension.ts (coordinator)
    ↓
Scanner.ts (execute ai-bom CLI)
    ↓
Parse CycloneDX JSON
    ↓
Update Components:
    ├─ ResultProvider (sidebar)
    ├─ SummaryProvider (sidebar)
    ├─ DiagnosticManager (Problems panel)
    └─ DecorationManager (inline)
```

### Error Handling

- Graceful degradation if ai-bom not installed
- User-friendly error messages
- Detailed logging to Output channel
- No crashes on invalid input

### Performance Considerations

- Scans run in separate process (non-blocking)
- Results cached until next scan
- Decorations update only on active editor change
- Lazy loading in tree views
- No continuous background scanning

## Integration Points

### With ai-bom CLI

- Executes via `child_process.exec()`
- Parses CycloneDX JSON output
- Maps severities and component types
- Extracts Trusera custom properties

### With VS Code API

| API | Usage |
|-----|-------|
| `vscode.commands` | Register commands |
| `vscode.window.createTreeView()` | Sidebar views |
| `vscode.languages.createDiagnosticCollection()` | Problems panel |
| `vscode.window.createTextEditorDecorationType()` | Inline decorations |
| `vscode.workspace.getConfiguration()` | Settings access |
| `vscode.window.createStatusBarItem()` | Status bar |
| `vscode.window.createOutputChannel()` | Debug output |

## Development Workflow

   ```bash
   npm install
   ```

2. **Add Extension Icon**
   - Create 128x128 PNG icon
   - Save as `images/icon.png`

   npm run compile
   ```

4. **Test Extension**
   ```bash
   code .
   # Press F5
   ```

### Short Term (Before publishing)

1. **Run Test Checklist**
   - Follow TEST_CHECKLIST.md
   - Fix any issues found
   - Document known limitations

2. **Add Screenshots**
   - Sidebar with scan results
   - Problems panel
   - Inline decorations
   - Status bar integration
   - Add to README.md

3. **Test with Real Projects**
   - LangChain repository
   - AutoGen repository
   - Custom test projects

4. **Cross-Platform Testing**
   - Test on Linux (done - developed here)
   - Test on macOS (if available)
   - Test on Windows (if available)

5. **Performance Testing**
   - Large projects (1000+ files)
   - Multiple scans in sequence
   - Memory leak testing

### Long Term (Future versions)

1. **Enhanced Features**
   - Quick fixes (CodeActions to update deps)
   - Baseline comparison (track changes over time)
   - Custom risk scoring rules
   - Export reports from sidebar
   - Multi-root workspace support

2. **Integrations**
   - GitLens integration (show component age)
   - GitHub Actions integration
   - CI/CD pipeline templates
   - Settings UI webview

3. **Community**
   - Publish to marketplace
   - Gather user feedback
   - Add telemetry (opt-in)
   - Create tutorial videos

## Known Limitations

1. **Icon**: Placeholder text file, needs actual 128x128 PNG
2. **Screenshots**: Not yet added to README
3. **Testing**: Manual testing only (no automated tests yet)
4. **Platform**: Primarily tested on Linux
5. **i18n**: English only (no internationalization)

## Dependencies

### Runtime Dependencies

None. The extension is self-contained, but requires:

- Python 3.10+ (on user's system)
- ai-bom CLI (offers to install automatically)

### Development Dependencies

From `package.json`:

```json
{
  "@types/node": "^20.10.0",
  "@types/vscode": "^1.85.0",
  "@typescript-eslint/eslint-plugin": "^6.15.0",
  "@typescript-eslint/parser": "^6.15.0",
  "eslint": "^8.56.0",
  "typescript": "^5.3.3",
  "@vscode/vsce": "^2.22.0"
}
```

Install with: `npm install`

## Security Considerations

- **Local Execution**: Extension runs entirely locally, no external network calls
- **No Telemetry**: No analytics or usage tracking
- **Trusted CLI**: Uses official ai-bom CLI from trusted source
- **File Access**: Only reads files in workspace (standard VS Code permission)
- **Subprocess Safety**: Python path configurable, commands sanitized
- **No Credentials**: Extension doesn't handle or store credentials

## Contributing

The extension is ready for community contributions:

1. Fork the ai-bom repository
2. Make changes in `vscode-extension/` directory
3. Test thoroughly (use TEST_CHECKLIST.md)
4. Submit pull request

See DEVELOPMENT.md for coding standards and guidelines.
