SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Keeping an accurate food diary is tedious: estimating portions, looking up nutrition values, and doing the daily calorie math by hand. This Skill automates meal logging from a photo or a short text description and keeps a running calorie and macro tally against your daily target. ## Core Features & Use Cases - Photo-based logging: Analyze meal photos or Nutrition Facts labels with vision to extract items, portion estimates, and per-item calorie/macro breakdowns. - Daily budget tracking: Maintain a dated markdown food log with per-meal subtotals and daily totals for calories, protein, fat, and carbs against your target. - Corrections and recurring items: Adjust logs when you state a corrected total, and reuse recent entries for recurring packaged items like protein bars or coffee. - Use Case: Snap a photo of your lunch and a snack label during the day; the Skill appends timestamped entries to today's log and reports "Down 780/1800 today, 1020 remaining, protein at 92/140g." ## Quick Start Ask the assistant to set a daily calorie target and log location, then send a meal photo or description and say "log this meal".

Frequently Asked Questions about meal-tracker

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I track calories from a photo of my food?

Send the meal photo and the Skill uses vision analysis to identify each food item, estimate portion sizes in common units, and produce a calorie and macro breakdown per item. It then logs the entries to your daily file and reports remaining calories.

How do I log food from a Nutrition Facts label?

Send a photo of the label and the Skill reads the exact visible values: serving size, calories, protein, fat, and carbs. One visible container is treated as one serving unless you say otherwise, and the entry is appended to today's log.

Can I correct a meal log total after entries are added?

Yes. State the corrected total, such as "make sure 3 bars total," and the Skill reads the current daily log, adjusts line items, and recalculates all subtotals and daily totals across every macro so the math stays consistent.

Does the meal tracker work with restaurant meals or unclear portions?

It uses chain restaurant nutrition data when available and estimates conservatively otherwise, flagging uncertainty in the response. Recurring packaged items reuse the most recent matching entry instead of asking for brand details again.

Where are food logs stored and is the data private?

Logs are stored only in your own files, such as an Obsidian vault or a notes folder you choose during setup. The Skill never sends food logs to third parties and does not provide medical advice, diagnosis, or supplement guidance.
