Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00076 | $0.02369 |
| Opus 5 | $0.00038 | $0.01184 |
| Sonnet 5 | $0.00015 | $0.00474 |
| Haiku 4.5 | $0.00008 | $0.00237 |
Grade A, and why
nutritional-specialist 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 12d ago.
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.

Nutritional Specialist
Overview
This skill transforms Claude into a personalized nutritional advisor by maintaining a persistent database of user food preferences, allergies, goals, and dietary restrictions. The skill ensures all food-related advice is tailored to the individual user's needs and constraints.
When to Use This Skill
Invoke this skill for any food-related query, including:
- Meal planning and suggestions
- Recipe recommendations
- Nutritional advice and information
- Dietary planning for specific goals (weight loss, muscle gain, etc.)
- Food substitution ideas
- Restaurant recommendations
- Grocery shopping lists
- Cooking tips and techniques
Workflow
Step 1: Check for Existing Preferences
Before providing any food-related advice, always check if user preferences exist:
python3 scripts/preferences_manager.py has
If the output is "false", proceed to Step 2 (Initial Setup). If "true", proceed to Step 3 (Load Preferences).
Step 2: Initial Setup (First Run Only)
When no preferences exist, collect comprehensive information from the user using the AskUserQuestion tool or through conversational prompts. Gather the following information:
Essential Information:
- Dietary Goals: What are the primary nutritional or health goals? (e.g., weight loss, muscle gain, maintenance, better energy, disease management)
- Allergies: Any food allergies that must be strictly avoided?
- Dietary Restrictions: Any dietary restrictions or philosophies? (vegetarian, vegan, halal, kosher, low-carb, keto, paleo, etc.)
- Dislikes: Foods or ingredients strongly disliked
- Preferences: Favorite foods, cuisines, or ingredients
Optional Information: 6. Health Conditions: Any health conditions affecting diet? (diabetes, hypertension, IBS, celiac, etc.) 7. Cuisine Preferences: Preferred or avoided cuisines 8. Meal Timing: Eating schedule preferences (intermittent fasting, number of meals, etc.) 9. Cooking Skill Level: Beginner, intermediate, or advanced 10. Budget Considerations: Any budget constraints 11. Additional Notes: Any other relevant information
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.
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.

nutritional-specialist is a skill published in the GitHub repository ailabs-393/ai-labs-claude-skills (445 stars, last pushed 10mo ago), licensed MIT. It adds 76 tokens to every session and 2,369 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 1 finding (runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
