Skill

Use this skill for anything related to food, nutrition, calories, macros, protein, fat, carbohydrates, fiber, vitamins, meal tracking, diet goals, weight management, or healthy eating. Triggers on: food names, meal logging ("I just had X", "log my lunch"), nutrition questions ("how many calories in X", "macros for Y"), diet setup ("track my calories", "set up nutrition tracking", "help me eat better"), barcode scans (8-13 digit numbers), and weekly/daily summaries. Also triggers when the user casually mentions food in passing — always offer to log it.

nutrition-cli

Look up nutrition data for any food, log meals, track daily intake against your goals, compare foods, estimate calorie burn, and view trends — all from the command line.

First run

On the very first message that triggers this skill, check if nutrition tracking is configured:

Run: nutrition config status

If output is "Not configured": Read and follow skill/ONBOARDING.md exactly.

If output is "Configured": Continue normally. Do not re-run onboarding.

Logging meals

Triggers: "I had X", "I ate X", "just had X", "log X", "add X to my food log", any food mentioned in passing.

Steps:

1. Extract food name and optional grams from the message. Examples: "200g chicken" → food="chicken breast", grams=200 "a big mac" → food="big mac", grams=null (use default 100g) "2 eggs" → food="eggs", grams=null (use default)

2. Run: nutrition search "{FOOD}" --grams {GRAMS} --format json Show the result summary (name, kcal, protein, fat, carbs). Ask: "Should I log this?" — wait for confirmation before writing.

3. On confirmation: Run: nutrition log "{FOOD}" --grams {GRAMS}

4. After logging, append one line to today's daily memory note (memory/YYYY-MM-DD.md): Format: - {TIME} · {FOOD_NAME} · {KCAL} kcal (P:{P}g F:{F}g C:{C}g) Then append running total: **Running total: {TOTAL_KCAL} / {TARGET} kcal**

   This write is mandatory — it's what makes "what have I eaten today?" instant.

5. Check for patterns (see Learning section below).

Memory note: Only write nutrition data to MEMORY.md and memory/ files in private/DM sessions. In group contexts, skip the memory write step and log only to log.json.

Answering questions without API calls

Use the cheapest source that can answer the question. Check in order:

1. Already in context (no tool call needed)

• "How many calories today?" / "What did I eat today?" / "What did I have for lunch?" → Read today's memory/YYYY-MM-DD.md — running total and all meals are already there
• "What's my target?" / "Am I on track today?" → Read MEMORY.md nutrition profile, compute from daily note total vs target
• "How many meals today?" → Run: nutrition log --check-today

2. Semantic / fuzzy recall (memory_search, no CLI call)

• "What did I eat last Tuesday?" / "What did I have on [specific date]?" → Search memory/YYYY-MM-DD.md for that date and read it directly
• "That pasta dish I made last month" / "The meal I had after the gym" → Run: memory_search "{phrase}" across memory/ daily notes — do NOT call the CLI

3. Structured math or trends (CLI reads log.json)

• "Average calories last 30 days" → nutrition summary --days 30
• "What's my protein been like this week?" → nutrition summary --week
• "Show me my trend" → nutrition trend --days 14
• "How many times have I had chicken?" → nutrition top-foods --days 90
• Historical date query → nutrition summary --date YYYY-MM-DD
• Weekly report → nutrition summary --week

4. New data only (USDA API call via CLI)

• Food lookup → nutrition search "{FOOD}" --grams {GRAMS} --format json
• Barcode → nutrition barcode {CODE}

Never jump to step 3 or 4 if step 1 or 2 can answer it.

What to learn and when to write it

Write silently — do not announce "I've updated your memory." Update memory when you observe patterns. Do not wait to be asked.

Food preferences

Trigger: user declines a suggested food, expresses dislike, or asks for an alternative ("I don't eat X", "I'm not a fan of Y", "can I have Z instead")

Action: append to "Learned food preferences" in MEMORY.md: - Dislikes: {FOOD} (noted {DATE}) or - Prefers {FOOD_A} over {FOOD_B} (noted {DATE})

Trigger: user asks for the same food 3+ times across different days

Action: append: - Frequently eats: {FOOD} (logged {N} times)

Meal timing drift

Trigger: after 7 days of tracking, actual meal times differ from stated times by >45 min on average

Action: update meal times in MEMORY.md "Nutrition profile" to match observed times. Say: "I've updated your meal times in my memory to match when you actually eat."

Calorie patterns

Trigger: user consistently goes over or under target by >15% for 5+ days

Action: append to MEMORY.md "Health context": Over: - Tends to exceed calorie target (observed {DATE}) Under: - Often under-eats on {DAY_PATTERN} (observed {DATE})

Do NOT suggest changing the target without being asked.

Health context

Trigger: user mentions health conditions, fitness goals, or medications ("I'm trying to lose weight", "I have diabetes", "I'm training for a marathon")

Action: append to MEMORY.md "Health context": - {HEALTH_NOTE} (mentioned {DATE})

Only write what the user explicitly stated. Never infer diagnoses.

Streak tracking

Trigger: every time a meal is logged

Action: Run: nutrition log --update-streak

Trigger: user misses a full day (no meals by 10pm)

Action: reset streak next morning. Do not mention it unless the user asks.

---

Setting up proactive reminders

Triggers: "set up reminders", "remind me to log meals", "set up daily tracking", or during onboarding step 6.

Ask the user which reminders they want and at what times before running any commands. Do not assume default times. Only create the cron jobs for the reminders they selected.

Available reminders:

Morning summary: Ask: "What time do you want your morning summary?" (e.g. 7am, 8:30am) Parse to hour H and minute M. Then run:

text

openclaw cron add \
  --name "nutrition-morning" \
  --cron "{M} {H} * * *" \
  --tz "{TIMEZONE}" \
  --session nutrition-tracker \
  --message "Run: nutrition summary --yesterday and present it clearly. \
    Compare totals to target from MEMORY.md. \
    If they hit their calorie goal yesterday, say so specifically. \
    If they're on a streak of 3+ days, mention it." \
  --announce

Evening check-in: Ask: "What time do you want your evening check-in?" (e.g. 7pm, 9pm) Parse to hour H and minute M (24h). Then run:

text

openclaw cron add \
  --name "nutrition-evening" \
  --cron "{M} {H} * * *" \
  --tz "{TIMEZONE}" \
  --session nutrition-tracker \
  --system-event "Evening nutrition check-in. Ask the user what they ate today. \
    For each food they mention, run: nutrition search '{food}' to get calories, \
    confirm with user, then run: nutrition log '{food}'. \
    After all meals logged, run: nutrition summary --today and show the result." \
  --wake now

Weekly report (always Monday): Ask: "What time on Monday do you want your weekly report?" (e.g. 9am) Parse to hour H and minute M. Then run:

text

openclaw cron add \
  --name "nutrition-weekly" \
  --cron "{M} {H} * * 1" \
  --tz "{TIMEZONE}" \
  --session nutrition-tracker \
  --message "Run: nutrition summary --week and nutrition top-foods --days 7. \
    Present a weekly report: average daily calories, best day, worst day, \
    protein compliance, current streak. Format as a short readable summary." \
  --announce

After setup: confirm which jobs were created and when they'll fire next. To view: openclaw cron list To disable a specific job: openclaw cron disable nutrition-evening (or -morning, -weekly)
