What it does
Pp Open Food Facts is an agent skill from mvanhorn/printing-press-library. Use Open Food Facts source-backed recipes for product lookup, structured search, nutrition summaries, allergen inspection, product comparison, and category samples. Trigger phrases: Open Food Facts, food barcode, nutrition facts, allergens, ingredients, product comparison, open-food-facts-pp-cli.
Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Productivity & Automation, covering Health and fitness tracking. The repository describes itself as: Official library of CLIs generated by the CLI Printing Press. Endorsed, tested, and community-contributed. The licence is Apache-2.0.
When your agent uses it
- Phrases: Open Food Facts
- Nutrition facts
- Product comparison
- Open-food-facts-pp-cli
Example prompts
- “/pp-open-food-facts”
Requirements
- Node.js
- Pre-approved tools (allowed-tools): Read, Bash
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Install via the Printing Press installer. It defaults binaries to $HOME/.local/bin on macOS/Linux and…
- Verify: open-food-facts-pp-cli --version
- Ensure the reported install directory is on $PATH for the agent/runtime that will invoke this skill.
What it can do on your machine
Read from SKILL.md and the folder at commit d9a1696. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadBash
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
gonpx
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
world.openfoodfacts.org
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Pp Open Food Facts loads about 1.5k tokens when it runs. Until then it costs about 79 tokens; SKILL.md has 570 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.
- NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
allowed-tools: Read, Bash
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Prerequisites: Install the CLI
This skill drives the open-food-facts-pp-cli binary. You must verify the CLI is installed before invoking any command from this skill. If it is missing, install it first:
- Install via the Printing Press installer. It defaults binaries to
$HOME/.local/binon macOS/Linux and%LOCALAPPDATA%\Programs\PrintingPress\binon Windows:bash npx -y @mvanhorn/printing-press-library install open-food-facts --cli-only - Verify:
open-food-facts-pp-cli --version - Ensure the reported install directory is on
$PATHfor 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:
go install github.com/mvanhorn/printing-press-library/library/food-and-dining/open-food-facts/cmd/open-food-facts-pp-cli@latestIf --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.
When To Use
Use open-food-facts-pp-cli when an agent needs source-backed Open Food Facts data:
- Fetch a product by barcode with source URL, identity, labels, countries, Nutri-Score, NOVA, Eco-Score, nutriments, and data-quality tags.
- Run bounded structured product search by category, brand, country, label, or nutrition grade.
- Summarize nutrition facts for one known barcode.
- Inspect ingredients, allergens, traces, additives, and data-quality tags for one known barcode.
- Compare a small set of barcode records without hiding per-product fetch errors.
- Fetch a small category sample and preserve Open Food Facts data caveats.
When Not To Use
- Do not use it for product edits, image uploads, account login, or session workflows.
- Do not use it for bulk harvesting or local database sync; use Open Food Facts CSV or JSONL exports for bulk access.
- Do not build search-as-you-type loops against the live API.
- Do not treat nutrition, ingredient, or allergen output as medical or dietary advice.
- Do not claim Open Food Facts data is complete, accurate, or authoritative.

Setup
No API key is required for read operations.
The module declares go 1.26.4 so environments with Go toolchain auto-download disabled should use Go 1.26.4 or newer for direct installs.
Open Food Facts asks every API client to send a custom User-Agent in the form AppName/Version (ContactEmail). Configure a request identity before regular or frequent use:
export OPEN_FOOD_FACTS_USER_AGENT="my-food-tool/1.0"
export OPEN_FOOD_FACTS_CONTACT_EMAIL="you@example.org"Optional local/staging override:
export OPEN_FOOD_FACTS_BASE_URL="https://world.openfoodfacts.org"Keep live usage within Open Food Facts' documented limits: 15 product read requests per minute per IP address, 10 search requests per minute per IP address, and no live API bulk harvesting.
Recipes
Product Lookup
open-food-facts-pp-cli product 3017620422003 --agentUse this when the workflow has a barcode and needs compact product identity, source URL, Nutri-Score/NOVA/Eco-Score fields, ingredient/allergen tags, nutriments, and data-quality caveats.
Structured Search
open-food-facts-pp-cli search --category "breakfast cereals" --country "united-states" --page-size 5 --agentUse this for bounded candidate discovery. Prefer structured filters over plain terms because Open Food Facts documents structured search in API v2 and does not provide full-text search in v2/v3 server-side APIs.
Nutrition Summary
open-food-facts-pp-cli nutrition 3017620422003 --agentUse this when a workflow needs nutriment fields, serving basis, Nutri-Score, NOVA, Eco-Score, source URL, and data-quality tags for one barcode.
Allergens And Ingredients
open-food-facts-pp-cli allergens 3017620422003 --agentUse this to inspect ingredient text, ingredient analysis tags, allergens, traces, additives, and data-quality tags. Keep the caveat that records are community-contributed.
Small Product Comparison
open-food-facts-pp-cli compare 3017620422003 5449000000996 --agentUse this for side-by-side comparison of two to five barcodes. The command returns successful products plus per-barcode errors when a lookup fails.
Category Sample
open-food-facts-pp-cli category "breakfast cereals" --page-size 5 --agentUse this to fetch a small product sample for a category through structured search. Do not page through many results as a bulk backend.
Source Coverage
open-food-facts-pp-cli sources --agent
open-food-facts-pp-cli doctor --agentUse these before larger workflows to confirm read-only posture, optional request identity, configured base URL, documented rate limits, and non-goals.
