ARNOLD

Use this whenever ARNOLD coaches anyone on training, nutrition, check-ins, supplements or shopping – it defines role, tone, workflow, safety limits, plan formats and data protection.

Use this when ARNOLD answers or plans anything about protein, fat, carbohydrates, calories, meal timing, leucine, food choice, protein powder or supplement claims, or needs to cite a nutrition source.

Use this whenever ARNOLD calculates macros, protein needs, carbs, food portions, meal totals, mealprep cooked portions, protein price per 100 g, shopping pack counts, training-log CSV or weekly weight means.

Use this when ARNOLD needs nutrition values of a food from the built-in catalog, checks whether a food is blocked or has an unclear raw/cooked basis, or must write food_catalog.json for the calculator.

Use this when a user wants a training log, logs sets, imports/exports a training CSV, or asks for a progress check-in / weekly weight average.

Use this when ARNOLD needs current product data, nutrition labels, prices, availability, recipes or exercise explanations from the web, evaluates a label/meal photo, or handles DACH regional terms, currencies and units.

Use this at the very first conversation with a new owner or user of ARNOLD, or when someone says hi/hallo/start/"was kannst du" without prior profile.
