📊 FEED QUALITY DASHBOARD

OVERALL PORTFOLIO HEALTH: [Score]/100 ([Excellent/Good/Needs Attention/Poor])

✅ HIGH PERFORMING FEEDS ([X] feeds):

  Status: [Status] | Last Update: [Time] | Priority: [Level]

• [Feed Name]: [Score]/100 - [Response Time]ms
  Status: [Status] | Last Update: [Time] | Priority: [Level]

⚠️ PERFORMANCE ISSUES ([X] feeds):
• [Feed Name]: [Score]/100 - [Issue Description]
  Problem: [Specific issue - slow response/stale content/accessibility]
  Impact: [Effect on threat intelligence]
  Recommendation: [Specific fix or alternative]

❌ OFFLINE/PROBLEM FEEDS ([X] feeds):

  Last Successful: [Timestamp]
  Action Required: [Immediate steps needed]

PERFORMANCE METRICS:
📈 Response Times:
• Average: [X]ms
• Fastest: [Feed Name] ([X]ms)
• Slowest: [Feed Name] ([X]ms)

📅 Update Frequency:
• Daily Updates: [X] feeds
• Weekly Updates: [X] feeds

🔧 OPTIMIZATION RECOMMENDATIONS:

HIGH IMPACT CHANGES:
1. [Recommendation]: [Expected improvement]
   • Action: [Specific steps to take]
   • Impact: [Quantified benefit]

2. [Recommendation]: [Expected improvement]
   • Action: [Specific steps to take]
   • Impact: [Quantified benefit]

FEED MANAGEMENT:
• Remove [X] low-performing feeds (save [X]% processing time)
• Add [X] missing coverage areas for your industry
• Upgrade [X] feeds to premium versions (improve coverage by [X]%)

ALTERNATIVE SOURCES:
• Replace [Feed Name] with [Alternative] (better [metric])

1. Run `/optimize-feeds` to apply automated improvements
2. Use `/add-feeds [industry]` to fill coverage gaps
3. Check `/status` for overall system health

Last Quality Check: [Timestamp]
Next Scheduled Check: [Timestamp]
```

## Quality Scoring Algorithm

Feed Quality Score = (Accessibility × 0.25) + (Relevance × 0.30) + (Timeliness × 0.25) + (Uniqueness × 0.20)

Where:
- **Accessibility**: Response time, uptime, SSL validity
- **Relevance**: Security content percentage, keyword density
- **Timeliness**: Update frequency, publication lag
- **Uniqueness**: Non-duplicate content percentage

## Performance Thresholds

- **Excellent**: Score ≥ 90
- **Good**: Score 70-89
- **Needs Attention**: Score 50-69
- **Poor**: Score < 50
