# Apple Health CSV Skill

Query Apple Health data from CSV exports. Works with any iOS app that exports HealthKit data
as CSV (Simple Health Export, Health Auto Export, etc.).

## Setup

1. Export health data from your iPhone using an app like **Simple Health Export** (free)
2. Transfer the CSV files to your Mac (via AirDrop, iCloud, or USB)
3. Place them in the skill data directory:

```bash
# Default location (auto-detected)
~/.openclaw/workspace-butler/health-data/

# Or specify a custom path
export HEALTH_DATA_DIR="/path/to/your/csv/files"
```

## Usage

```bash
# List available health metrics
python3 scripts/health_query.py list

# Get a comprehensive daily health summary
python3 scripts/health_query.py summary

# Query a specific metric (last 7 days by default)
python3 scripts/health_query.py query HeartRate
python3 scripts/health_query.py query StepCount --days 14
python3 scripts/health_query.py query SleepAnalysis --days 7
python3 scripts/health_query.py query OxygenSaturation --days 30

# JSON output for programmatic use
python3 scripts/health_query.py query HeartRate --days 7 --json
python3 scripts/health_query.py summary --json
```

## Tips for Agents

1. Start with `summary` to get a quick overview of today's health
2. Use `--json` flag when you need structured data for analysis
3. Sleep data is grouped by night (cross-midnight sessions handled correctly)
4. Blood oxygen values are auto-converted from 0-1 decimal to percentage
5. Cumulative metrics (steps, calories, exercise time) show daily totals
6. Rate metrics (heart rate, SpO2) show daily averages with min/max range
