Romuald Członkowski	03c4e3b9a5	Merge pull request #194 from czlonkowski/templates-update Summary Major enhancement to the template system with AI-powered metadata generation, smart template discovery, and improved search capabilities for n8n workflow templates. Key Achievements 📈 5x more templates: Expanded from 499 to 2,596 high-quality templates 🤖 AI-powered metadata: Automatic generation of structured metadata using OpenAI 🔍 Smart template discovery: Search by complexity, setup time, required services, and more 🗜️ Efficient compression: Gzip compression keeps database size manageable 🚀 Token usage reduced by 80-90%: New flexible retrieval modes 🎯 Fuzzy node matching: Find templates using similar node types Major Features Added 1. AI-Powered Template Metadata Generation 🤖 Structured metadata automatically generated for all templates using OpenAI Batch processing with OpenAI Batch API for cost-effective generation Rich categorization: Categories, complexity levels, use cases, key features Setup time estimates: Helps users understand implementation effort Target audience identification: Matches templates to user roles Required services tracking: Lists external APIs and services needed 2. Smart Template Discovery System 🔍 New Search Capabilities Search by metadata: Filter templates by categories, complexity, setup time Multi-faceted search: Combine filters for precise template discovery Fuzzy node matching: Find templates with similar nodes (e.g., Gmail ≈ Outlook) SQL injection protection: Secure parameterized queries throughout New MCP Tools for Template Discovery search_templates_by_metadata: Smart search with metadata filters list_node_templates: Find templates using specific nodes (with fuzzy matching) get_templates_for_task: Curated templates for common tasks list_templates: Browse all templates with metadata 3. Template System Infrastructure 🏗️ Database Enhancements New metadata columns: metadata_json, metadata_generated_at Gzip compression: Workflow JSONs compressed (12MB vs 75MB uncompressed) Quality filtering: Only templates with >10 views included Token sanitization: Automatic removal of API keys/secrets from templates Flexible Retrieval Modes Three response modes for different use cases: nodes_only: Just node types and names (minimal tokens) structure: Nodes with positions and connections (moderate detail) full: Complete workflow JSON (maximum detail) 4. Comprehensive Testing & Security 🛡️ Security Features SQL injection prevention: All queries use parameterized statements Input validation: Comprehensive sanitization of user inputs Token removal: Automatic sanitization of API keys in templates Directory traversal protection: Safe file path handling Test Coverage ✅ 25+ integration tests for metadata operations ✅ 20+ security tests for SQL injection prevention ✅ Unit tests for all new components ✅ Performance tests for batch processing ✅ All tests passing (120+ tests total) Impact Analysis Metric Main Branch This PR Change Template Count 499 2,596 +420% (5x) Templates with Metadata 0 2,596 100% coverage Search Capabilities Basic text Smart metadata filters Major enhancement Token Usage (minimal mode) 100% 10-20% 80-90% reduction Database Size ~40MB ~48MB +20% (acceptable) New API Examples Smart Template Search // Find simple automation templates that take less than 30 minutes to set up search_templates_by_metadata({ category: 'automation', complexity: 'simple', maxSetupMinutes: 30 }, limit: 10) Fuzzy Node Matching // Find templates with email nodes (matches Gmail, Outlook, SMTP, etc.) list_node_templates({ nodeTypes: ['n8n-nodes-base.gmail'] }) // Automatically finds templates with similar email nodes Task-Based Discovery // Get curated templates for specific tasks get_templates_for_task({ task: 'webhook_processing' }) Metadata Statistics // Get insights into template metadata coverage get_metadata_stats() // Returns: { total: 2596, withMetadata: 2596, outdated: 0, ... } Files Changed Summary New Components src/templates/metadata-generator.ts: OpenAI metadata generation src/templates/batch-processor.ts: Batch API processing src/utils/node-similarity.ts: Fuzzy node matching logic src/utils/template-sanitizer.ts: Token removal and sanitization tests/integration/templates/metadata-operations.test.ts: Integration tests tests/unit/templates/template-repository-security.test.ts: Security tests Enhanced Components src/templates/template-repository.ts: Metadata operations & smart search src/templates/template-service.ts: Pagination & flexible retrieval src/templates/template-fetcher.ts: Metadata generation integration src/mcp/tools.ts: New template discovery tools src/database/schema.sql: Metadata columns added Migration Notes Existing databases will be automatically migrated on first run Metadata generation is optional (use --generate-metadata flag) All existing tools remain backward compatible Compression is transparent to API consumers Test Plan Run full test suite: npm test Test metadata generation with OpenAI Verify smart search capabilities Test fuzzy node matching Verify SQL injection prevention Test compression/decompression Verify pagination logic Test all three get_template modes Check memory usage with large templates Test with n8n-mcp-tester agent Documentation Updated README with new template tools Added metadata generation guide in docs/ Claude Project Setup updated with new capabilities	2025-09-15 10:09:10 +02:00
