MyFitnessClaw

This skill manages your nutritional data and provides a visual dashboard for tracking macros and micronutrients using OpenClaw's native tools.

Core Files (Skill Assets)

assets/nutrition/daily_macros.json: The structured log of daily intake.
assets/nutrition/targets.json: Daily nutritional goals (calories, protein, carbs, fats, and 10 essential micronutrients).
assets/nutrition/insights.json: AI-generated tips based on current progress.
assets/nutrition/foods/common.md: A reference list of frequently eaten foods and their macros/micros.
assets/canvas/index.html: The visual dashboard for the OpenClaw Canvas.

Workflow: Logging Food

When the user mentions eating something:

Estimate Macros & Micros: If the user doesn't provide them, estimate:
- Macros: Calories, protein, carbs, fats.
- Micros: Vitamin D3, Magnesium, Potassium, Zinc, Vitamin B6, Vitamin B12, Selenium, Vitamin C, Vitamin A, Vitamin E. Check assets/nutrition/foods/common.md first.
Update Daily Log (Canonical): Update assets/nutrition/daily_macros.json. Include the micros object for both individual meals and the daily total.
Update Offline Mirror: Update assets/canvas/offline_data.js with the same data, ensuring micronutrients are included.
- Overwrite the file with: window.__OFFLINE_DAILY_MACROS = [...]; window.__OFFLINE_TARGETS = {...}; window.__OFFLINE_INSIGHTS = {...};
- This ensures the dashboard works when opened via file:// (offline/browser-first).
Update Memory: Log the meal in the agent's current daily memory file (e.g., memory/YYYY-MM-DD.md).
Show Dashboard: Use canvas(action=present, url='skills/my-fitness-claw/assets/canvas/index.html') to show the updated dashboard inside OpenClaw.
Provide Browser Access: After every log, provide the following message:
📊 View in your browser:
- Quick: Open skills/my-fitness-claw/assets/canvas/index.html in your browser (uses offline mirror).
- Full: Run python -m http.server 8000 from the workspace root and visit http://localhost:8000/skills/my-fitness-claw/assets/canvas/index.html.
Generate Insights: Analyze progress against goals in assets/nutrition/targets.json and update assets/nutrition/insights.json.

Persistence Rules:

assets/nutrition/*.json: Canonical storage.
assets/canvas/offline_data.js: Mirror for file:// viewing only.
Do not modify assets/canvas/index.html during routine logging.
