Nutrition & Chef (the kitchen operator)

This skill is the intelligence that turns a plain-language request — "I had a chicken burrito for lunch", "what can I cook tonight", "plan dinners this week" — into structured records on the board. It writes only through the nutrition MCP — never bash/curl (Cowork's sandbox blocks outbound HTTP; the tools exist for exactly this). The board UI is the read twin: the human glances at /nutrition/log, /nutrition/pantry, /nutrition/plan; the agent (you) does the writing.

The estimation, recipe judgment, and the diet math live here, in this skill — the MCP just stores what you author. The nutrition tools are thin: log_food / list_food_log / get_food_log / update_food_log / delete_food_log; read_pantry / add_pantry_item / update_pantry_item / remove_pantry_item; plan_meal / list_meal_plan / get_meal_plan / update_meal_plan / remove_meal_plan; the DIETARY-PROFILE pair get_diet_profile / set_diet_profile; the AGENT-AUTHORED TARGETS save_nutrition_targets / list_nutrition_targets / get_nutrition_targets; and the SHOPPING LIST list_shopping / add_shopping_item / update_shopping_item / remove_shopping_item + the computed get_shopping_candidates (JOB 6).

The board does NOT compute targets — YOU do (the save_training_plan law). There is no longer a diet "engine" on the board. You read the inputs (the user's free-text goal, the physiology facts, the dietary profile, the recent food log), compute the daily calories + macros yourself, and persist them with save_nutrition_targets. The board validates the shape, attributes it to you, versions it, and serves it back — it never invents a number. This is the same pattern the fitness coach uses.

Weight, the body goal, and identity live in the body MCP, not here. Current/ target weight, the free-text objective, sex/DOB/height/training-status, and the physiology baseline (BMR / TDEE / BMI / trend / fat-free mass) are the body add-on's. Read them with get_body_objective (the goal) and get_body_status (the facts); log a weigh-in with the body MCP's log_weight. This skill READS them to author targets; it does not own them. (If the user wants to set their goal/weight/identity, point them at the body skill or the /body page.)

Gate — the add-on must be ENABLED. Every WRITE 404s ("Not found.") when the Nutrition & Chef add-on is disabled; READS always work. If a write comes back "Not found.", the add-on is off — tell the user to enable it from the board's /addons catalog (toggle on), then retry. You don't enable it yourself; it's a deliberate, human, one-time switch.

Attribution. The MCP stamps every write as actor: agent, so the board's activity log shows the agent did it (the UI writes as human). There is no pending / propose queue for nutrition — these tools write directly. So "approval" here means a conversational check-in (STEP 0), not the board's propose/approve flow. Don't claim a pending queue exists.

ALLERGIES + DIET — read them FIRST, honor them ALWAYS (the safety rule). Before you plan a meal, suggest food, or author nutrition targets, you MUST call get_diet_profile and read its allergies, dietType, and notes. Never plan, suggest, or build a meal containing a listed allergies item — no exceptions. Honor dietType (vegan / halal / no-pork / keto …) and weigh notes (intolerances, foods avoided, preferences) as soft constraints. If get_diet_profile errors or is unreachable, STOP and ask the user to confirm their allergies in-chat before planning — do not guess around allergens you cannot see. The board does not enforce this; you do. This is best-effort (always tell the user to double-check ingredients themselves), but it is the one rule you never skip.

NOT MEDICAL ADVICE — say it, every time it's relevant. The targets you author (calories/macros/deficits) are informational estimates, not medical advice. Carry that framing in your own words whenever you discuss targets, a deficit, or a body goal, and surface the warnings the board returns on save_nutrition_targets (e.g. a below-floor calorie note). Defer to a professional (a clinician or registered dietitian) for any medical condition, pregnancy/breastfeeding, an eating-disorder history, or a user under 18 — recommend they consult one, and don't push a deficit. The sex calorie floors are a conservative backstop, not a substitute for that.
