Ultrahuman analytics

This skill implements multi-day analytics, predictions, correlations, reports, and engagement on top of Ultrahuman data. Always use the ultrahuman_mcp tool ultrahuman_get_daily_metrics once per date, then aggregate and interpret in your response. Never invent data; only use what the API returns.

Prerequisites

• - ultrahumanmcp must be available. Use email from ULTRAHUMANEMAIL or user message.
• Dates in YYYY-MM-DD. For "last 7 days" compute the 7 dates ending yesterday (or today if user says "including today").
• All workflows are read-only and descriptive (no medical advice).

1. Analytics and evaluations

1.1 Weekly report

Trigger: "weekly report", "last 7 days summary", "how was my week", "week in review".

Steps:

1. 1. Call ultrahumangetdailymetrics for each of the last 7 days (same email). Use response_format: "json" if you need to parse programmatically, or "markdown" and extract numbers from the summary.
2. For each day extract: sleep score, recovery score, HRV (avg), night RHR, steps. If present: metabolicscore, timeintarget, average_glucose.
3. Compute: averages for sleep, recovery, HRV, steps; best night (highest recovery or sleep score, state which date); worst night (lowest); day-over-day deltas (e.g. "Recovery improved 3 days in a row, then dropped").
4. Reply with: one short paragraph summary, then a small table (date | sleep | recovery | HRV | steps), then 1–2 bullet insights (e.g. "Best night: Wed (recovery 8). Recovery trend: improving into mid-week.").

1.2 Sleep consistency score

Trigger: "sleep consistency", "how consistent is my sleep", "sleep variability".

Steps:

1. 1. Fetch last 7–14 days via ultrahumangetdailymetrics (one call per date).
2. From each day's sleep object get: total sleep (from quickmetrics), sleep efficiency, and if available bedtime (from details). Compute standard deviation or range for total sleep and efficiency.
3. Derive a simple "consistency" statement: e.g. "You're highly consistent (sleep within 30 min and efficiency within 5% most nights)" or "Sleep duration varied by ~1h this week – consider more consistent bedtimes."
4. No formal score required; descriptive summary is enough.

1.3 Recovery trend

Trigger: "recovery trend", "recovery over the week", "how is my recovery trending", "recovery last 14 days".

Steps:

1. 1. Fetch 7 or 14 days (one call per date).
2. Extract per day: recovery score or recoveryindex, HRV avg, nightrhr avg.
3. Build a table: date | recovery | HRV | night RHR. Add a one-line trend: "Improving", "Declining", "Stable", or "Recovery dipped mid-week then recovered."
4. If recovery dropped for 3+ days in a row, add a short note: "Consider lighter days or more sleep" (descriptive only).

1.4 Metabolic week

Trigger: "metabolic week", "glucose this week", "time in target last 7 days", "metabolic summary".

Steps:

1. 1. Fetch last 7 days.
2. From each day get: metabolicscore, timeintarget, averageglucose, glucose_variability (if present). If a day has no CGM data, note "No CGM data for [date]."
3. Compute weekly averages for the metrics that exist. Optionally compare to the previous 7 days if user asked for "vs last week" (then fetch 14 days and split).
4. Reply: "Metabolic week: average time in target X%, avg glucose Y mg/dL, variability Z%. [One-line comparison if previous week requested.]"

1.5 VO2 and movement trend

Trigger: "VO2 trend", "movement this week", "activity trend", "steps and VO2".

Steps:

1. 1. Fetch last 7 days.
2. Extract: steps (avg), movementindex, vo2max per day where available.
3. Weekly average for steps and movementindex; if vo2max is present, note trend (up/stable/down) or latest value.
4. One sentence: "Activity trend: [up/stable/down]. Weekly avg steps: X. Movement index avg: Y."

1.6 Deep / REM balance

Trigger: "deep sleep", "REM sleep", "sleep stages", "deep vs REM".

Steps:

1. 1. Fetch last 7 days (or N user specified).
2. From each day's sleep details.sleepstages get: deepsleep %, lightsleep %, remsleep %, awake %.
3. Compute average % deep and average % REM over the period. Note if one is consistently low (e.g. "REM averaged 12% – some research associates higher REM with memory and mood; consider sleep consistency."). Descriptive only, no diagnosis.

2. Predictions and readiness

2.1 Tomorrow readiness

Trigger: "tomorrow readiness", "will I be ready tomorrow", "am I set for tomorrow".

Steps:

1. 1. Fetch last night's (or the most recent night's) data with ultrahumangetdaily_metrics.
2. Read: sleep score, recovery score, HRV.
3. Heuristic (descriptive only): "When recovery is above 7 and sleep above 6, your numbers typically support a solid next day. Your last night: recovery X, sleep Y – [so your numbers suggest good readiness / suggest paying attention to rest today]."
4. Do not promise outcomes; only describe what the numbers often indicate.

2.2 Training load check

Trigger: "I trained hard yesterday", "training load", "did I recover from my workout", "heavy training yesterday".

Steps:

1. 1. Fetch yesterday and optionally today (or 2–3 days including the training day).
2. Compare recovery, sleep, HRV on the night after the training day to the user's recent baseline (e.g. 7-day average). If no baseline yet, use the same night's values only.
3. Reply: "After your training day, last night's recovery was [X]. [Compared to your recent average, that's typical / below your average – your body may need more recovery before the next hard session.]" Descriptive only.

2.3 Low-recovery alert

Trigger: "low recovery", "recovery alert", "am I overreaching", "recovery slipping".

Steps:

1. 1. Fetch last 7 days.
2. Compute 7-day average recovery (or recovery_index). Count how many of the last 3 nights were below that average.
3. If 2 or 3 of the last 3 nights are below average: "Last 3 nights your recovery was below your 7-day average – consider lighter days or more sleep."
4. If not, briefly summarize: "Your last 3 nights are in line with or above your weekly average."

2.4 Glucose spike risk (pattern)

Trigger: "glucose and sleep", "does sleep affect my glucose", "glucose spike risk".

Steps:

1. 1. Fetch last 7–14 days.
2. For each day: total sleep (from sleep details) or sleep score, and glucosevariability or averageglucose (if CGM data exists).
3. Split days into "shorter sleep" (e.g. <6h or sleep score <5) vs "longer sleep". Compute average glucose variability (or average glucose) for each group.
4. One sentence pattern: "On days when you slept under 6h, your glucose variability averaged X% vs Y% on longer-sleep days." No causation; present as observed pattern only.

3. Correlations and insights

3.1 Sleep–glucose link

Trigger: "sleep and glucose", "sleep glucose link", "how does sleep affect my glucose".

Steps:

1. 1. Fetch 7–14 days.
2. For each day: total sleep or sleep score; timeintarget and/or averageglucose.
3. Group days by e.g. "7+ hours sleep" vs "under 7 hours". Average timeintarget (and optionally averageglucose) per group.
4. Reply: "When you slept 7+ hours, time in target averaged X%. When you slept less, it averaged Y%." No causation; pattern only.

3.2 Sleep–recovery link

2. From each day: sleep efficiency (from sleep details quickmetrics), recovery score or recoveryindex.
3. Group by efficiency (e.g. ≥85% vs <85%). Average recovery per group.
4. Reply: "Your recovery tends to be higher when sleep efficiency is above 85% (avg recovery X vs Y when efficiency is lower)."

3.3 Rest day effect

Trigger: "rest day", "days I didn't train", "recovery after rest".

Steps:

1. 1. Fetch last 7–10 days.
2. Use steps (or movement_index) as a proxy for activity: "high steps" vs "low steps" days. Define thresholds simply (e.g. above/below median steps).
3. Compare average recovery and sleep score (and HRV if you like) on "low steps" days vs "high steps" days.
4. Reply: "On lower-activity days your recovery averaged X vs Y on higher-activity days." Descriptive only.

3.4 Weekday vs weekend

Trigger: "weekday vs weekend", "weekend sleep", "do I sleep better on weekends".

Steps:

1. 1. Fetch last 14 days (to get at least two weekends).
2. Label each date as weekday (Mon–Thu) or weekend (Fri–Sun), or Mon–Fri vs Sat–Sun depending on user wording.

General rules

• - Always use ultrahumangetdaily_metrics with the user's email and correct YYYY-MM-DD dates. One call per date; then aggregate in your answer.
• Never invent or assume data. If a day has no data, say so and skip or note "No data for [date]."
• Tone: Descriptive and supportive. "Your data shows …", "On average …". No medical diagnosis or treatment advice.
• Missing metrics: If CGM or VO2 is not in the response, skip those parts and report what is available.
• Output: Prefer short summary first, then table or bullets, then one-line takeaway. For "export" or "PDF", output copy-paste-ready text.

Use references/metrics_glossary.md and references/interpretation.md from the ultrahuman-biodata-assistant skill when you need definitions or interpretation heuristics.
