fitness-nutrition

fitness-nutrition is a skill for Claude Code, Codex from nobodyohm-web/Thot. It costs 20 tokens per session (2,910 once invoked), scanned A, a copy of fitness-nutrition, MIT.

A collection of workout, food, and body-measurement tools using public exercise and nutrition databases plus offline calculations. TDEE means the estimated calories your body uses in a day, and macros are protein, carbohydrates, and fat.

In plain words
What is it for?
Planning workouts, finding exercises by muscle or equipment, checking food calories and protein, planning meals, estimating BMI, body fat, TDEE, one-rep maxes, and macro targets.
Why use it?
It brings exercise lookups, meal information, and common training calculations into one workflow without requiring paid data services or extra Python packages.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

fitness-nutrition scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/body_calc.py, scripts/nutrition_search.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Fitness & Nutrition

Expert fitness coach and sports nutritionist skill. Two data sources plus offline calculators — everything a gym-goer needs in one place.

Data sources (all free, no pip dependencies):

  • wger (https://wger.de/api/v2/) — open exercise database, 690+ exercises with muscles, equipment, images. Public endpoints need zero authentication.
  • USDA FoodData Central (https://api.nal.usda.gov/fdc/v1/) — US government nutrition database, 380,000+ foods. DEMO_KEY works instantly; free signup for higher limits.

Offline calculators (pure stdlib Python):

  • BMI, TDEE (Mifflin-St Jeor), one-rep max (Epley/Brzycki/Lombardi), macro splits, body fat % (US Navy method)

When to Use

Trigger this skill when the user asks about:

  • Exercises, workouts, gym routines, muscle groups, workout splits
  • Food macros, calories, protein content, meal planning, calorie counting
  • Body composition: BMI, body fat, TDEE, caloric surplus/deficit
  • One-rep max estimates, training percentages, progressive overload
  • Macro ratios for cutting, bulking, or maintenance

Procedure

Exercise Lookup (wger API)

All wger public endpoints return JSON and require no auth. Always add format=json and language=2 (English) to exercise queries.

Step 1 — Identify what the user wants:

  • By muscle → use /api/v2/exercise/?muscles={id}&language=2&status=2&format=json
  • By category → use /api/v2/exercise/?category={id}&language=2&status=2&format=json
  • By equipment → use /api/v2/exercise/?equipment={id}&language=2&status=2&format=json
  • By name → use /api/v2/exercise/search/?term={query}&language=english&format=json
  • Full details → use /api/v2/exerciseinfo/{exercise_id}/?format=json

Step 2 — Reference IDs (so you don't need extra API calls):

Exercise categories:

ID Category
8 Arms
9 Legs
10 Abs
11 Chest
12 Back
13 Shoulders
14 Calves
15 Cardio

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
