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

## Key Findings by Category
|
|
|
|
### Validation Issues
|
|
- Most common error category (96.6% of all errors)
|
|
- Workflow-level validation: 39.11% of validation errors
|
|
- Generic error messages prevent self-resolution
|
|
- See: TELEMETRY_ANALYSIS_REPORT.md, Section 2
|
|
|
|
### Tool Reliability Issues
|
|
- `get_node_info` critical (11.72% failure rate)
|
|
- Information retrieval tools less reliable than state management tools
|
|
- Validation tools consistently underperform (5.5-6.4% failure)
|
|
- See: TELEMETRY_ANALYSIS_REPORT.md, Section 3 & TECHNICAL_DEEP_DIVE.md, Section 4
|
|
|
|
### Performance Bottlenecks
|
|
- Sequential operations extremely slow (55+ seconds)
|
|
- Read-after-write pattern inefficient (96.6 seconds)
|
|
- Search refinement rate high (17% need multiple searches)
|
|
- See: TELEMETRY_ANALYSIS_REPORT.md, Section 4 & TECHNICAL_DEEP_DIVE.md, Section 6
|
|
|
|
### User Behavior
|
|
- Top searches: test (5.8K), webhook (5.1K), http (4.2K)
|
|
- Most searches indicate where users struggle
|
|
- Session metrics show healthy engagement
|
|
- See: TELEMETRY_ANALYSIS_REPORT.md, Section 6
|
|
|
|
### Temporal Patterns
|
|
- Error rate volatile with significant spikes
|
|
- October incident period with slow recovery
|
|
- Currently stabilizing at 60-65 errors/day baseline
|
|
- See: TELEMETRY_ANALYSIS_REPORT.md, Section 9 & TECHNICAL_DEEP_DIVE.md, Section 5

|
|
|
### Error Analysis
|
|
```sql
|
|
-- Error type distribution
|
|
SELECT error_type, SUM(error_count) as total_occurrences
|
|
FROM telemetry_errors_daily
|
|
WHERE date >= CURRENT_DATE - INTERVAL '90 days'
|
|
GROUP BY error_type ORDER BY total_occurrences DESC;
|
|
|
|
-- Temporal trends
|
|
SELECT date, SUM(error_count) as daily_errors
|
|
FROM telemetry_errors_daily
|
|
WHERE date >= CURRENT_DATE - INTERVAL '90 days'
|
|
GROUP BY date ORDER BY date DESC;
|
|
```
|
|
|
|
### Tool Performance
|
|
```sql
|
|
-- Tool success rates
|
|
SELECT tool_name, SUM(usage_count), SUM(success_count),
|
|
ROUND(100.0 * SUM(success_count) / SUM(usage_count), 2) as success_rate
|
|
FROM telemetry_tool_usage_daily
|
|
WHERE date >= CURRENT_DATE - INTERVAL '90 days'
|
|
GROUP BY tool_name
|
|
ORDER BY success_rate ASC;
|
|
```
|
|
|
|
### Validation Errors
|
|

|
|
-- Validation errors by node type
|
|
SELECT node_type, error_type, SUM(error_count) as total
|
|
FROM telemetry_validation_errors_daily
|
|
WHERE date >= CURRENT_DATE - INTERVAL '90 days'
|
|
GROUP BY node_type, error_type
|
|
ORDER BY total DESC;
