• MCP Tools Expert skill — The highest-priority skill that guides correct n8n-mcp tool usage, covering tool selection, nodeType format differences, validation profiles, smart parameters, and auto-sanitization.
• Workflow Patterns skill — Provides 5 proven architectural patterns (webhook processing, HTTP API, database, AI, scheduled) drawn from 2,653+ real n8n templates, with a creation checklist and pattern selection guide.
• Validation Expert skill — Interprets validation errors, guides fixing them, and handles false positives, preventing agents from getting stuck in validation error loops.
• Operation-aware configuration — Teaches correct node configuration based on operation type, ensuring nodes are set up properly with their dependencies.
