Diagnoses and resolves n8n workflow validation errors using iterative troubleshooting and best-practice guidance.
The n8n Validation Expert is a specialized Claude Code skill designed to streamline the n8n workflow development process by providing expert interpretation of validation results. It guides users through the iterative 'validate-fix' cycle, helping to resolve issues ranging from missing required fields and type mismatches to complex expression syntax errors. With support for multiple validation profiles like 'runtime' and 'ai-friendly,' as well as an auto-sanitization system for node operators, this skill ensures that automations are both functionally sound and aligned with n8n best practices.
