# Vital Prompt

Extract vital sign measurements.

User said: "{{INPUT}}"
Language: {{LANGUAGE}}

IMPORTANT: Respond with ONLY the JSON object. No explanations, no markdown fences, no text before or after.

```json
{
  "question": "tracking question in {{LANGUAGE}}",
  "type": "vital_type",
  "input_type": "form",
  "schedule": [{"days": [...], "time": "HH:MM"}],
  "input_config": {"fields": [...]},
  "entry": {"value": "...", "data": {...}}
}
```

## Schedule format

- `days`: array of "mon", "tue", "wed", "thu", "fri", "sat", "sun"
- `time`: 24h format "08:00", "12:00", "18:00" etc.
- Daily = all 7 days: ["mon", "tue", "wed", "thu", "fri", "sat", "sun"]
- "once" or one-time measurement = null (no schedule, no recurring prompt)

## Vital types and units

| blood_glucose | glucose | mg/dL, mmol/L |
