- Add node type existence validation that catches invalid types
- Fix critical issue: now catches 'nodes-base.webhook' BEFORE database lookup
- Add smart suggestions for common mistakes (webhook → n8n-nodes-base.webhook)
- Add minimum viable workflow validation (prevents single-node workflows)
- Add empty connection detection for multi-node workflows
- Add helper functions for workflow structure examples and fix suggestions
- Prevent AI agents from creating workflows with question mark nodes
