meal-tracker

meal-tracker is a skill for Claude Code, Codex from AtlasOmnia/donna-starter. It costs 34 tokens per session (1,155 once invoked), scanned A, original, MIT.

A meal log that records food from a photo or written description, estimates or reads its nutrition, and keeps a dated Markdown record. It compares daily calories and optional protein, fat, and carbohydrate targets.

In plain words
What is it for?
Use it to record meals, estimate portions and nutrition, track progress against daily targets, and maintain food logs in a notes app or chosen folder.
Why use it?
It removes the need to calculate each meal and maintain a food diary by hand. It can use exact values from a visible Nutrition Facts label when available.

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

meal-tracker scanned grade A with 0 findings 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 9d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Meal Tracker

Log meals from a photo or a text description, track calories and macros against the user's daily budget, and keep a dated markdown food log.

Setup (ask once, then remember)

  • Daily calorie target and optional macro targets (protein/fat/carbs in grams).
  • Log location — the user's notes app or a folder (for example an Obsidian vault, ~/Food Logs, or their notes directory). Ask once; do not assume a path.
  • If the user later changes the target, update the stored value and the current log header.

Meal logging workflow

Photo input (user sends image)

  1. Use vision_analyze with the image — ask: "Identify each food item, estimate portion sizes in common units (oz, cups, pieces), and provide calorie + macro breakdown per item."
  2. If the photo is clearly a Nutrition Facts label, skip broad estimation and use the exact visible label values: serving size, calories, protein, fat, carbs, and useful notes (sodium/fiber/sugar). Treat one visible bag/container as one serving unless the user says otherwise.
  3. If the user combines text + image (e.g. "add 1 coffee and this"), log both in the same timestamped meal/snack section.
  4. For quick repeated "Add" messages with a label photo, use the visible label values, append a timestamped snack/drink section to today's log, recalculate totals, and verify the file. Do not ask for product names when the label gives enough to log an accurate entry.
  5. A bare food/label image after an active food-log exchange is an implicit "add this" — log one serving/container from the visible label unless the image suggests multiple servings.
  6. If today's log is missing but the chat already contains same-day entries, reconstruct the daily log from the conversation before appending.
  7. Parse the response into structured entries, log to the daily file, and report: items logged, calories used, remaining for the day.

Text input (user describes a meal)

  1. Estimate portions from common serving sizes when not specified; flag uncertain estimates.
  2. Use standard nutrition values (USDA) for known foods.
  3. For recurring packaged items ("the protein bars", "same coffee"), reuse the most recent matching line item's calories/macros and mention that briefly.
  4. Log to the daily file and report remaining calories.
