What is the recommended validation loop process?

It follows an iterative pattern: configure the node, validate, interpret errors (typically taking 23s), apply fixes (typically taking 58s), and re-validate until successful.

How does this skill handle n8n validation profiles?

It guides you through choosing the right profile for your current stage, such as 'runtime' for pre-deployment checks or 'ai-friendly' to reduce noise during AI-assisted development.

Can it fix errors automatically?

The skill provides an auto-sanitization system for operator structure issues and offers specific code-level fixes for required fields, expressions, and data type mismatches.

How do I handle validation false positives?

The skill identifies common false positives like 'missing retry logic' and suggests using the 'ai-friendly' profile to suppress warnings that may be acceptable in non-critical environments.

生产力与工作流

Diagnoses and resolves n8n workflow validation errors, warnings, and structure issues through iterative feedback loops and best-practice guidance.

关于

The n8n Validation Expert skill transforms Claude into a specialized consultant for building robust n8n workflows by interpreting complex validation results. It assists developers in navigating the iterative 'validate-and-fix' cycle, explaining error severity from critical blocks to performance warnings. With deep knowledge of n8n's validation profiles—minimal, runtime, ai-friendly, and strict—and automatic sanitization rules for operators, this skill ensures that nodes are configured correctly, expressions are syntactically sound, and workflow connections are healthy before production deployment.
