Does it support n8n expression syntax validation?

Yes, it detects invalid expression syntax, such as missing double curly braces or incorrect node references, and provides the correct syntax format.

Can this skill automatically fix my n8n workflow?

It provides auto-sanitization for common operator structure issues (like binary vs. unary metadata) and gives clear instructions for fixing more complex errors manually.

How many validation cycles are usually required to fix a node?

Telemetry shows that most node configurations require 2 to 3 'validate-and-fix' cycles to reach a fully valid state.

What is the benefit of the 'ai-friendly' validation profile?

The ai-friendly profile is designed specifically for AI-generated configurations, reducing false positives and noise while still catching critical errors that would block execution.
