Systematically debug failing n8n workflows — expression errors, node type mismatches, pinned data issues, sub-workflow failures, authentication problems, rate limit errors, and silent data loss. Use this skill whenever the user reports an n8n workflow problem — phrases like "my n8n workflow is failing", "this expression isn't working", "why is this node returning empty", "debug this error", "n8n execution log shows", "workflow runs but no output". Also use when pasted error messages reference n8n concepts (ItemLists, expressions, credentials). Apply this skill before guessing a fix — n8n failures have specific diagnostic patterns, and guessing typically makes the problem worse.
