## 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

## SQL Queries Reference

All analysis derived from these core queries:

### 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
```sql
-- 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;
```
