Day-by-day Garmin health metrics as a compact table (max 31 days, default last 7).

Columns: date, steps, resting_hr (bpm), hrv_avg (ms overnight), hrv_status (balanced/unbalanced/low), bb_high/bb_low (Body Battery 0-100), stress_avg (0-100), intensity_min (moderate + 2x vigorous), active_kcal. For sleep detail use garmin_get_sleep; for workouts use garmin_list_activities.

Garmin sleep data per night as a compact table (max 31 days, default last 7).

Columns: date (wake-up morning), score (0-100), quality, duration, deep, light, rem, awake (H:MM), overnight_hrv (ms), spo2_avg (%), resting_hr (bpm). Note: if the user also wears an Oura ring, oura_* tools report the same nights and may differ slightly; say which source you're citing.

List Garmin activities in a date range as a compact table (max 90 days, default last 30).

Columns: activity_id (for garmin_get_activity_detail), date, type, name, distance_km, duration (H:MM), avg_hr, max_hr, pace_or_speed, elev_gain_m, aerobic_te (training effect 0-5), anaerobic_te.

Deep-dive a single Garmin activity: distance, time, HR, pace/speed, cadence, power, elevation, calories, training effect — plus lap splits and heart-rate-zone breakdown in 'detailed' mode. Get activity_id from garmin_list_activities first.

Current Garmin training snapshot in one call: training readiness score, training status (e.g. productive/maintaining/strained), acute load, VO2max, HRV status, and race time predictions (5K/10K/half/marathon). Use this for 'how is my training going / how recovered am I' questions; combine with oura_* readiness for cross-source checks.

Body composition entries (Garmin Index scale or manual) as a table (max 90 days, default last 30). Columns: date, weight_kg, body_fat_pct, muscle_mass_kg, body_water_pct, bmi. Only days with a measurement appear.
