Root cause: AI agents were placing error handling properties inside `parameters` instead of at node level Major changes: - Enhanced workflow validator to check for ALL node-level properties (expanded from 6 to 11) - Added validation for onError property values and deprecation warnings for continueOnFail - Updated all examples to use modern error handling (onError instead of continueOnFail) - Added comprehensive node-level properties documentation in tools_documentation - Enhanced MCP tool documentation for n8n_create_workflow and n8n_update_partial_workflow - Added test script demonstrating correct node-level property usage Node-level properties now validated: - credentials, disabled, notes, notesInFlow, executeOnce - onError, retryOnFail, maxTries, waitBetweenTries, alwaysOutputData - continueOnFail (deprecated) Validation improvements: - Detects misplaced properties and provides clear fix examples - Shows complete node structure when properties are incorrectly placed - Type validation for all node-level boolean and string properties - Smart error messages with correct placement guidance 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
