Input
The user provides: $ARGUMENTS
This may be:
- "full" or empty (default: run all checks)

- "deep" for extended checks including database integrity
Procedure
Run health checks in this order:
1. API Health
curl -sf http://localhost:4820/api/health
- Verify HTTP 200 response
- Check response time (<500ms expected, <1000ms acceptable)
- Confirm JSON response body
2. Database Health
curl -sf http://localhost:4820/api/stats
- Verify stats endpoint returns valid data
- Check that counts are non-negative integers
- Verify database file exists and has reasonable size
3. WebSocket Health
- Check that the WebSocket server is listening
- Verify WebSocket upgrade is supported on the dashboard port
4. API Endpoint Validation
Test each major endpoint:
curl -sf http://localhost:4820/api/sessions?limit=1
curl -sf http://localhost:4820/api/events?limit=1
curl -sf http://localhost:4820/api/analytics
curl -sf http://localhost:4820/api/pricing
curl -sf http://localhost:4820/api/settings/info
5. Hook Integration
- Verify hook handler script exists
- Check hooks are configured in
~/.claude/settings.json
- Verify the handler script targets the correct dashboard URL
6. Disk & Resource Usage (deep mode only)
- Database file size
- Log file sizes (if any)
- Available disk space
- Node.js process memory usage (if accessible)
7. Data Freshness
- Time since last event ingested
- Time since last session created
- Check for stale active sessions (active but no events in >1 hour)
