Clear Thought 1.5

# Notebook Enhancement Proposals Based on analysis of srcbook implementations, here are proposed enhancements for the ClearThought notebook integration. ## Priority 1: High-Value, Low-Risk Features ### 1. Named Cells with Filenames **Current State**: Cells have auto-generated IDs **Proposed Enhancement**: Add optional `filename` field to cells ```typescript interface Cell { id: string; filename?: string; // e.g., "helper-functions.js" // ... existing fields } ``` **Benefits**: - Better organization and readability - Easier cell referencing - Export to actual file structure ### 2. Cell Import/Export System **Current State**: Cells execute in isolation **Proposed Enhancement**: Shared execution context with module-like exports ```javascript // Cell 1: math-utils.js export const sum = (a, b) => a + b; // Cell 2: calculator.js import { sum } from './math-utils.js'; console.log(sum(2, 3)); // 5 ``` **Implementation**: - Maintain a shared context object across cell executions - Parse exports and make them available to other cells - Use VM context sharing for imports ### 3. Package.json Cell Type **Current State**: No dependency management **Proposed Enhancement**: Special cell type for dependencies ```typescript interface PackageJsonCell extends Cell { type: 'package.json'; dependencies?: Record<string, string>; devDependencies?: Record<string, string>; } ``` **Benefits**: - Clear dependency declaration - Version management - Export compatibility with npm projects ## Priority 2: Medium-Value Features ### 4. TypeScript Support **Current State**: JavaScript only **Proposed Enhancement**: Add TypeScript compilation - Use TypeScript compiler API for type checking - Support `.ts` extensions on cells - Provide type hints and IntelliSense data ### 5. Environment Variables **Current State**: No environment variable support **Proposed Enhancement**: Controlled environment variable access ```typescript interface NotebookConfig { // ... existing config allowedEnvVars?: string[]; // Whitelist specific env vars } ``` **Security**: Only allow explicitly whitelisted environment variables ### 6. Persistent Outputs **Current State**: Outputs cleared on re-execution **Proposed Enhancement**: Maintain output history ```typescript interface Cell { // ... existing fields outputHistory?: Output[][]; // Keep last N execution outputs } ``` ## Priority 3: Advanced Features (Future Consideration) ### 7. Long-Running Process Support **Current State**: Synchronous execution with timeout **Proposed Enhancement**: Background process management - Support for WebSocket servers - Process lifecycle management - Inter-process communication ### 8. External HTTP Requests **Current State**: No network access **Proposed Enhancement**: Controlled HTTP client - Whitelist allowed domains - Rate limiting - Request/response logging ### 9. Multi-Language Support **Current State**: JavaScript only **Proposed Enhancement**: Python, SQL, etc. - Language-specific execution engines - Cross-language data sharing - Polyglot notebooks ## Implementation Roadmap ### Phase 1 (Immediate) - [ ] Named cells with filenames - [ ] Cell import/export system - [ ] Package.json cell type ### Phase 2 (Near-term) - [ ] TypeScript support - [ ] Environment variables (whitelisted) - [ ] Output history ### Phase 3 (Long-term) - [ ] Long-running processes - [ ] External HTTP (with restrictions) - [ ] Multi-language support ## Security Considerations All enhancements must maintain security: 1. **No filesystem access** - All operations remain in-memory 2. **No unrestricted network** - Whitelist-only approach 3. **No arbitrary code execution** - VM sandbox remains 4. **No credential exposure** - Secrets handled securely 5. **Resource limits** - CPU, memory, and time bounds ## Migration Path These enhancements would be backward compatible: 1. Existing notebooks continue to work 2. New features are opt-in via configuration 3. Export formats support both old and new structures ## Testing Strategy Each enhancement requires: 1. Unit tests for new functionality 2. Integration tests with existing features 3. Security audit for attack vectors 4. Performance benchmarks 5. Documentation updates ## Example Enhanced Notebook ```typescript // Create notebook with enhanced features const notebook = notebookStore.createNotebook(sessionId, { enableImports: true, enableTypeScript: true, allowedEnvVars: ['API_KEY', 'DEBUG_MODE'] }); // Add package.json cell notebookStore.addCell(notebook.id, 'package.json', JSON.stringify({ dependencies: { 'lodash': '^4.17.21' } })); // Add TypeScript cell with filename notebookStore.addCell(notebook.id, 'code', ` export interface User { name: string; age: number; } export const createUser = (name: string, age: number): User => ({ name, age }); `, 'typescript', 0, { filename: 'user-model.ts' }); // Add cell that imports from previous notebookStore.addCell(notebook.id, 'code', ` import { createUser } from './user-model.ts'; const user = createUser('Alice', 30); console.log(user); `, 'typescript', 1, { filename: 'main.ts' }); ``` ## Conclusion These enhancements would bring ClearThought's notebook functionality closer to full srcbook parity while maintaining security and simplicity. The phased approach allows incremental improvement based on user needs and feedback.
