Diet Tracker

This skill helps track daily diet and achieve weight loss goals with automated meal reminders.

Trigger Conditions

User might say:

• "I had [food] for lunch/dinner"
• "What's my remaining calorie budget?"
• "How many calories have I eaten today?"
• "Log my meal"
• "Check my diet progress"

Or automatically triggered by cron job for meal reminders.

Cron Job Integration

This skill works with automated cron jobs:

• Lunch reminder: ~12:30 (checks if lunch logged, sends reminder if not)
• Dinner reminder: ~18:00 (checks if dinner logged, sends reminder if not)

Cron job system event: 饮食记录检查:午餐 or 饮食记录检查:晚餐

User Profile (Required)

The skill reads from USER.md:

• Daily calorie target (default: 1650 kcal)
• Macronutrient targets (protein/carbs/fat)
• Height, weight, age, gender, activity level (for TDEE calculation)

Activity levels:

• Sedentary (little or no exercise)
• Lightly active (light exercise 1-3 days/week)
• Moderately active (moderate exercise 3-5 days/week)
• Very active (hard exercise 6-7 days/week)
• Extra active (very hard exercise + physical job)

Workflow

When User Logs a Meal:

1. Identify food items from user's description
2. Fetch nutrition data via scripts/get_food_nutrition.py
   • MUST GET: calories(kcal), protein(g), carbs(g), fat(g)
   • Queries SkillBoss API Hub for calorie/protein/carbs/fat info
   • Falls back to references/food_database.json if needed
   • If complete nutrition data cannot be found, MUST clearly inform user of estimated values
3. Update daily log via scripts/update_memory.py
   • Saves to memory/YYYY-MM-DD.md
   • RECORD FORMAT: Food Name - XX kcal (P: XXg, C: XXg, F: XXg)
   • Calculates meal totals
   • Updates daily running totals
4. Report to user:
   • MUST REPORT: calories + protein/carbs/fat grams
   • Today's consumed / remaining calories
   • MUST REPORT: Remaining macronutrient budgets
   • Predicted weight change based on deficit/surplus

When User Asks for Status:

1. Read current day's memory file
2. Calculate totals consumed
3. Report:
   • Remaining calorie budget
   • Remaining protein/carbs/fat (if targets set)
   • Weight change prediction

Scripts

• scripts/get_food_nutrition.py: Fetches nutrition info via SkillBoss API Hub + calculates TDEE
• scripts/update_memory.py: Updates daily memory file with meal data
• references/food_database.json: Fallback database of common foods

Error Handling

Common Issues

Issue: "Cannot read USER.md" or missing user data

• Cause: User profile not configured
• Solution: Ask user for height, weight, age, gender, activity level, and calorie target

Issue: Nutrition lookup fails for uncommon foods

• Cause: Food not found in local database or SkillBoss API Hub response lacks structured data
• Solution: Ask user for approximate calorie count or use similar food from database
