Functions exposed to the LLM to take actions

Name	Description
get_heart_rateA	Get the most recent heart rate reading from Apple Watch. Returns: JSON object with fields: bpm - heart rate in beats per minute timestamp - ISO-8601 UTC time of the reading source - device/app that recorded the reading device - Apple Watch model (may be null)
stream_heart_rateA	Collect heart rate readings from Apple Watch over a time window. Runs the HealthKit observer for the given duration and returns all samples received, including any buffered readings from the last 5 minutes that hadn't been reported yet. Note: Apple Watch syncs data through iPhone to Mac via iCloud, so "real-time" updates have network-dependent latency (typically 10-60 s). Args: duration_seconds: How long to collect readings (1–300 s). Default 30. Returns: JSON array of heart rate samples, ordered by timestamp.
get_heart_rate_historyA	Retrieve heart rate history stored in macOS HealthKit. Returns all samples recorded within the past N hours, sorted oldest-first. Data comes from Apple Watch and any other HealthKit sources (e.g. Workout app). Args: hours: How many hours of history to fetch (default 24, max ~168 for a week). Returns: JSON array of heart rate samples, each with bpm / timestamp / source / device.
