Health Overview

Goal

Combine multiple data sources into one comprehensive health snapshot. Correlate poor sleep with elevated resting heart rate, reference biomarker trends alongside activity, etc.

Tool sequence

1. getProfile() — identify the user
2. listConnectedDevices() — see what data is actually available
3. For each connected device category, call the relevant data tool:
   • getVitals — heart rate, HRV, blood pressure, SpO2
   • getSleepData — nightly sleep summaries
   • getActivityData — steps, workouts, calories
   • getBodyComposition — weight, body fat, BMI
4. searchBiomarkers — recent lab results
5. getBiologicalAge() — biological age trend

Date range guidance

• Default to the last 7-14 days for wearables
• Always pass zoneId with the user's IANA timezone — daily aggregations align with the local day
• Skip wearable tools if the relevant device isn't connected (saves a round trip)

Synthesis tips

• Cross-reference: a spike in resting heart rate often correlates with poor sleep the night before
• Surface out-of-range biomarkers prominently
• Note data freshness — biomarkers older than 90 days should be flagged for retest

Variant: minimal "vital signs" check

1. getProfile()
2. getBiologicalAge()
3. searchBiomarkers(range: "OUT_OF_RANGE")

Three calls, fast, useful for low-context check-ins.
