Enhanced tools documentation, duplicate ID errors, and AI Agent validator based on telemetry analysis of 593 validation errors across 3 categories: - 378 errors: Duplicate node IDs (64%) - 179 errors: AI Agent configuration (30%) - 36 errors: Other validations (6%) Quick Win #1: Enhanced tools documentation (src/mcp/tools-documentation.ts) - Added prominent warnings to call get_node_essentials() FIRST before configuring nodes - Emphasized 5KB vs 100KB+ size difference between essentials and full info - Updated workflow patterns to prioritize essentials over get_node_info Quick Win #2: Improved duplicate ID error messages (src/services/workflow-validator.ts) - Added crypto import for UUID generation examples - Enhanced error messages with node indices, names, and types - Included crypto.randomUUID() example in error messages - Helps AI agents understand EXACTLY which nodes conflict and how to fix Quick Win #3: Added AI Agent node-specific validator (src/services/node-specific-validators.ts) - Validates prompt configuration (promptType + text requirement) - Checks maxIterations bounds (1-50 recommended) - Suggests error handling (onError + retryOnFail) - Warns about high iteration limits (cost/performance impact) - Integrated into enhanced-config-validator.ts Test Coverage: - Added duplicate ID validation tests (workflow-validator.test.ts) - Added AI Agent validator tests (node-specific-validators.test.ts:2312-2491) - All new tests passing (3527 total passing) Version: 2.22.12 → 2.22.13 Expected Impact: 30-40% reduction in AI agent validation errors Technical Details: - Telemetry analysis: 593 validation errors (Dec 2024 - Jan 2025) - 100% error recovery rate maintained (validation working correctly) - Root cause: Documentation/guidance gaps, not validation logic failures - Solution: Proactive guidance at decision points References: - Telemetry analysis findings - Issue #392 (helpful error messages pattern) - Existing Slack validator pattern (node-specific-validators.ts:98-230) Concieved by Romuald Członkowski - www.aiadvisors.pl/en
