- `ai-bom.severityThreshold` - Filter by severity
- `ai-bom.deepScan` - Enable AST analysis
- `ai-bom.showInlineDecorations` - Show/hide decorations
- `ai-bom.autoInstall` - Auto-install ai-bom

### Integration

- Parses CycloneDX JSON output
- Maps to VS Code APIs (diagnostics, decorations, tree views)
- Respects workspace configuration
- Handles errors gracefully

## Technology Stack

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

## Next Steps

### 1. Install Dependencies

```bash
cd vscode-extension
npm install
```

This installs:
- TypeScript 5.3.3
- @types/vscode ^1.85.0
- @types/node ^20.10.0
- ESLint and TypeScript ESLint
- vsce (VS Code Extension Manager)

### 2. Add Extension Icon

Create a 128x128 PNG icon:

```bash
# Copy Trusera logo or create custom icon
cp /path/to/logo.png images/icon.png
```

The icon should use the shield/security theme to match the extension purpose.

### 3. Compile TypeScript

```bash
npm run compile
```

This generates JavaScript in the `out/` directory.

### 4. Test the Extension

**Option A: Launch Extension Development Host**

1. Open the folder in VS Code:
   ```bash
   code vscode-extension
   ```

2. Press F5 to launch Extension Development Host

3. In the new window, open a project with AI dependencies

4. Run "AI-BOM: Scan Workspace" from Command Palette

**Option B: Install Locally**

1. Package the extension:
   ```bash
   npm run package
   ```

2. Install the .vsix file:
   ```bash
   code --install-extension ai-bom-scanner-0.1.0.vsix
   ```

### 5. Test with Real Projects

Test with projects that have AI dependencies:

```bash
# Clone and test with LangChain
git clone https://github.com/langchain-ai/langchain /tmp/langchain
code /tmp/langchain
# Run: AI-BOM: Scan Workspace

# Clone and test with AutoGen
git clone https://github.com/microsoft/autogen /tmp/autogen
code /tmp/autogen
# Run: AI-BOM: Scan Workspace
```

Verify:
- Components are detected correctly
- Severity levels are accurate
- File paths and line numbers work
- Inline decorations appear
- Problems panel shows diagnostics
- Sidebar navigation works

### 6. Fix Any Issues

Common issues to check:

- Python path resolution
- CycloneDX parsing
- File path normalization (Windows vs Unix)
- Error handling and user messages
- Performance with large codebases

### 7. Add Screenshots

Take screenshots for README:

1. Sidebar with scan results
2. Problems panel with diagnostics
3. Inline decorations in code
4. Status bar integration

Add to README.md under "Screenshots" section.

### 8. Publish to Marketplace

When ready:

1. Update version if needed
2. Test thoroughly
3. Follow publishing steps in DEVELOPMENT.md
4. Submit to VS Code Marketplace

## Architecture Decisions

### Why CycloneDX Format?

- Industry standard SBOM format
- Already supported by ai-bom CLI
- Rich metadata (properties, version, etc.)
- Easy to parse and extend

### Why Child Process for CLI?

- Avoids Python/Node integration complexity
- Uses stable ai-bom CLI interface
- Easy to upgrade ai-bom independently
- Familiar to users (same CLI they know)

### Why Separate Tree Providers?

- Results and Summary have different data structures
- Allows independent updates
- Cleaner code organization
- Better VS Code API pattern

### Why Strict TypeScript?

- Catches bugs at compile time
- Better IDE support
- Self-documenting code
- Enterprise-grade quality

## Comparison to Similar Extensions

### Advantages

- First extension for AI/ML component scanning
- Integrated with Problems panel
- Inline risk scores
- Multiple severity levels
- Works with existing ai-bom tool
- Open source (Apache 2.0)

### Similar Extensions

- **Snyk**: General vulnerability scanning (no AI-specific)
- **SonarLint**: Code quality (no AI-specific)
- **Trivy**: Container scanning (limited AI detection)

### Unique Features

- AI-specific component detection
- Risk scoring (0-100)
- OWASP LLM Top 10 mapping
- n8n workflow scanning
- MCP server detection
- Agent framework analysis

## Potential Enhancements

Future versions could add:

1. **Workspace Trust Integration**: Respect VS Code workspace trust
2. **Multi-root Workspace Support**: Scan multiple folders
3. **Quick Fixes**: CodeActions to update dependencies
4. **Baseline Comparison**: Compare scans over time
5. **Custom Rules**: User-defined risk scoring
6. **Export Reports**: Save reports from sidebar
7. **GitLens Integration**: Show component age in Git blame
8. **GitHub Actions**: Trigger scans on PR
9. **Real-time Scanning**: Scan on file edit (debounced)
10. **Settings UI**: Custom webview for configuration

## Performance Considerations

- Scans run in separate Python process (non-blocking)
- Results cached until next scan
- Decorations update only on active editor change
- Tree views use lazy loading
- No continuous background scanning (manual trigger only)

## Security Considerations

- Extension runs locally (no external network calls)
- Uses official ai-bom CLI (trusted codebase)
- No telemetry or analytics
- Respects .ai-bomignore files
- File paths sanitized before display
