n8n Validation Expert

Expert guide for interpreting and fixing n8n validation errors.

When to Use

  • You need to interpret or fix validation errors in an n8n workflow.
  • The task involves missing_required, invalid_value, expression failures, or iterative validate-fix loops.
  • You want concrete remediation guidance for workflow validation output.

Core Workflow

  1. Confirm the request matches this skill's trigger, scope, and risk profile.
  2. Use the topic map to identify the relevant pattern, checklist, or example before writing detailed guidance or code.
  3. Load references/full-guidance.md when implementation details, examples, anti-patterns, validation checks, or edge cases are needed.
  4. Apply only the relevant guidance instead of loading or repeating the entire reference by default.
  5. Verify the result against any validation checks, limitations, security notes, or platform constraints in the reference.

Topic Map

  • Validation Philosophy
  • Error Severity Levels
  • Errors (Must Fix)
  • Warnings (Should Fix)
  • Suggestions (Optional)
  • The Validation Loop
  • Pattern from Telemetry
  • Example
  • Validation Profiles
  • minimal
  • runtime (RECOMMENDED)
  • ai-friendly
  • strict
  • Common Error Types
  • missing_required
  • invalid_value
  • type_mismatch
  • invalid_expression

Reference Map

  • references/full-guidance.md preserves the complete original guidance, including examples and detailed edge cases.

Limitations

  • Use this skill only when the task clearly matches the scope described above.
  • Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
  • Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.

Progressive Loading

Keep this SKILL.md as the compact routing and workflow entrypoint. Load the reference file only when the user task requires the deeper implementation material.
