n8n-validation-expert is a SKILL.md that an AI coding agent loads to interpret n8n validation errors and guide fixes. It bundles an error catalog, a false-positives reference, and a review checklist, and explains severity levels, validation profiles, and the validation loop for n8n-mcp's validate_node and validate_workflow tools.
Reach for it whenever a validate_node or validate_workflow call returns errors or warnings, since it distinguishes real errors from known false positives and maps each issue to a fix.
Use it to
- Interpret errors and warnings from validate_node or validate_workflow results
- Identify which validation warnings are false positives
- Choose and understand the four cumulative validation profiles
- Follow the validation loop and auto-fix process after failed validation
- Look up specific error types like missing_required or type_mismatch
