pp-nutrition
One agent-native CLI over USDA FoodData Central and NutritionValue.org - with cross-source enrichment, protein-density comparison, nutrient ranking, and a local SQLite cache no other nutrition tool ships. Trigger phrases: `nutrition facts for`, `how much protein in`, `compare calories of`, `net carbs in`, `foods highest in`, `log what I ate`, `use nutrition`, `run nutrition-pp-cli`.
Why this skill is useful
Adds a CLI tool that provides unique nutrition data enrichment and offline caching capabilities not available in public APIs.

What this skill does
Nutrition (USDA FoodData Central + NutritionValue.org) — Printing Press CLI Prerequisites: Install the CLI This skill drives the nutrition-pp-cli binary. You must verify the CLI is installed before invoking any command from this skill. If it is missing, install it first: 1. Install via the Printing Press installer. It defaults binaries to $HOME/.local/bin on macOS/Linux and %LOCALAPPDATA%\Programs\PrintingPress\bin on Windows: 2. Verify: nutrition-pp-cli --version 3. Ensure the reported install directory is on $PATH for the agent/runtime that will invoke this skill. If the npx install fails (no Node, offline, etc.), fall back to a direct Go install (requires Go 1.26.6 or newer). This installs into $GOPATH/bin (default $HOME/go/bin), so add that directory to $PATH instead: If --version reports "command not found" after install, the runtime cannot see the binary directory on $PATH. Do not proceed with skill commands until verification succeeds. Look up any food's nutrition from USDA's ~600K-food database, then enrich it with NutritionValue.org's derived analytics (net carbs, omega-6/omega-3 ratio) that the USDA API never exposes. Compare foods on a per-100kcal protein-density basis, rank foods by any nutrient, filter by compound thresholds, and log a daily diary against targets - all offline-cached, cited, and agent-native. When to Use This CLI Use this CLI when an agent or user needs trustworthy, citable food nutrition data: looking up macros and micros for a food, comparing foods by protein density or on a common basis, ranking foods by a nutrient, finding foods that meet compound dietary thresholds, enriching a USDA record with NutritionValue.org's derived analytics, or logging a daily food diary against targets. It is offline-cached and agent-native, so repeated lookups and aggregations are cheap and the numbers always trace to a real USDA fdcId. …
How to use it
Reference it in AdaL, Claude Code, Cursor or any coding agent — nothing to install:
