Execution Flow

Step 1: Understand Requirements

Analyze the description to identify:

• Primary business questions
• Target audience and their expertise level
• Key decisions this dashboard supports
• Required time granularity

ai.analyze({
  input: context.description,
  output: "dashboard_requirements",
  extract: [
    "business_questions",
    "audience_type",
    "decision_context",
    "metric_priorities"
  ]
})

Step 2: Discover Available Data

warehouse.query({
  query: "SHOW TABLES",
  catalog: "analytics"
})

// For each relevant table
warehouse.query({
  query: "DESCRIBE [table]"
})

Step 3: Design Dashboard Structure

Based on audience and questions:

• Select layout template
• Map metrics to cards
• Choose visualizations
• Define drill-down paths

Step 4: Build Queries

For each metric:
  warehouse.query({
    query: buildMetricQuery(metric, dimensions, filters),
    validate: true
  })

Step 5: Create Dashboard

metabase.create_dashboard({
  name: context.name,
  description: context.description,
  collection_id: getCollectionId(context.audience),
  parameters: [
    { name: "date_range", type: "date/range", default: context.time_range }
  ]
})

Step 6: Add Cards

For each card in design:
  metabase.create_card({
    dashboard_id: dashboard.id,
    name: card.title,
    visualization_type: card.viz_type,
    query: card.query,
    position: card.position,
    size: card.size
  })

Step 7: Configure Refresh & Alerts

metabase.set_refresh({
  dashboard_id: dashboard.id,
  frequency: context.refresh_frequency
})

Response Format

## Dashboard Created

**Name**: [Dashboard Name]
**URL**: [Dashboard URL]
**Audience**: [Target audience]
**Refresh**: [Frequency]

### Dashboard Structure

#### KPI Row
| Card | Metric | Visualization | Query |
|------|--------|---------------|-------|
| 1 | [Total Revenue] | Big Number | [Summary] |
| 2 | [Active Users] | Big Number + Sparkline | [Summary] |
| 3 | [Conversion Rate] | Gauge | [Calculation] |

#### Charts Row
| Card | Title | Type | Dimensions |
|------|-------|------|------------|
| 4 | Revenue Trend | Line | Date (daily) |
| 5 | Users by Segment | Bar | Segment |

#### Details Row
| Card | Title | Type | Data |
|------|-------|------|------|
| 6 | Top Products | Table | Top 10 |
| 7 | Regional Breakdown | Map | By region |

### Filters Available

| Filter | Type | Default |
|--------|------|---------|
| Date Range | Date picker | Last 30 days |
| Segment | Dropdown | All |
| Region | Multi-select | All |

### Queries Used

**Card 1: Total Revenue**
```sql
SELECT 
  SUM(amount) as total_revenue,
  SUM(amount) - LAG(SUM(amount)) OVER (ORDER BY date) as change
FROM orders
WHERE date >= {{date_start}}
  AND date <= {{date_end}}

Card 2: Active Users

SELECT 
  COUNT(DISTINCT user_id) as active_users
FROM events
WHERE timestamp >= {{date_start}}
  AND timestamp <= {{date_end}}

Design Decisions

Suggested Enhancements

Usage Tips

For [audience]:

• Use date filter to change time range
• Click on [segment] to filter all charts
• Hover on charts for detailed values
• Click card title to expand

Next Steps

1. Share with [audience] for feedback
2. Set up alert for [critical metric]
3. Schedule weekly email digest

## Metric Query Patterns

### Growth Metrics
```sql
-- MoM Growth
SELECT 
  DATE_TRUNC('month', date) as month,
  SUM(value) as current,
  LAG(SUM(value)) OVER (ORDER BY month) as previous,
  (SUM(value) - LAG(SUM(value)) OVER (ORDER BY month)) / 
    LAG(SUM(value)) OVER (ORDER BY month) * 100 as growth_pct
FROM metrics
GROUP BY 1

Cohort Metrics

-- Retention by Cohort
SELECT 
  cohort_month,
  months_since_signup,
  COUNT(DISTINCT user_id) as users,
  COUNT(DISTINCT user_id) / FIRST_VALUE(COUNT(DISTINCT user_id)) 
    OVER (PARTITION BY cohort_month ORDER BY months_since_signup) as retention
FROM user_activity
GROUP BY 1, 2

Guardrails

• Always validate queries before adding to dashboard
• Ensure data access permissions match audience
• Don't expose PII in shared dashboards
• Test with date range edge cases
• Include data freshness indicator
• Add helpful descriptions to cards
• Use consistent number formatting
• Optimize queries for performance (avoid full scans)
• Consider mobile viewing for key dashboards
• Version control dashboard definitions when possible
