Implements comprehensive guidance for using n8n-mcp MCP tools effectively. This is the HIGHEST PRIORITY skill that addresses the 20% MCP tool failure rate. Files created: - 5 evaluations testing tool selection, nodeType formats, validation, and smart parameters - SKILL.md (505 lines) - Core tool usage guide with telemetry insights - SEARCH_GUIDE.md (243 lines) - Node discovery tools (search, essentials vs info) - VALIDATION_GUIDE.md (377 lines) - Configuration validation and auto-sanitization - WORKFLOW_GUIDE.md (385 lines) - Workflow management with 15 operation types - README.md - Skill metadata emphasizing highest priority Key features: - Tool selection guide with success rates (search_nodes 99.9%, get_node_essentials 91.7%) - nodeType format distinction (nodes-base.* vs n8n-nodes-base.*) - Validation profiles explained (minimal/runtime/ai-friendly/strict) - Smart parameters for IF/Switch nodes (branch="true", case=0) - Auto-sanitization system for operator structures - Telemetry insights (56s between edits, 18s search→essentials, 23s+58s validate→fix) - AI connection types (8 types documented) Total: ~1,650 lines across 10 files Based on analysis of 447,557 real MCP tool usage events. 🤖 Conceived by Romuald Członkowski - https://www.aiadvisors.pl/en
