Compare Food Products Side-by-Side

off_compare_products

Read-onlyIdempotent

Side-by-side nutrition and scoring comparison for 2–10 products per call by barcode; a repeated barcode is compared once, so two identical barcodes yield one row, and barcodes past the 10th distinct one are listed in unprocessed rather than fetched. Returns a normalized table of energy (kcal), fat, saturated fat, carbohydrates, sugars, salt, protein, and fiber per 100 g, or per 100 ml for liquids, plus Nutri-Score, NOVA group, and Green-Score. Open Food Facts returns one preparation state per read, so figures for the prepared product arrive in a prepared object on the row, with the same columns and basis, and never fill an as-sold field. Designed for "which of these cereals is healthiest?" or "compare these pasta brands" workflows. Missing nutrition data for any product is preserved as absent — comparisons are not imputed. A batch is not all-or-nothing: barcodes that resolve are returned even when others fail, with confirmed-missing barcodes listed in not_found and failed fetches listed separately in failed. Scores carry regional formula caveats. Data under ODbL 1.0 — cite Open Food Facts in downstream use.

Input Schema

Name	Required	Description	Default
`barcodes`	Yes	Barcodes to compare, returned as one row each in input order; a repeated barcode is compared once, so two identical barcodes yield one row. One call compares at most 10 distinct barcodes: up to 100 are accepted, and those past the 10th distinct one are returned in unprocessed without being fetched. Example: ["3017620422003", "7622210100146"].

Output Schema

Name	Required	Description
`error`	No	Present when the call failed. Absent on success.
`failed`	No	Barcodes whose fetch failed, with the per-barcode reason. Absent when every fetch completed. A barcode listed here is unknown, not absent from Open Food Facts — retry it with off_get_product before concluding anything about the product.
`products`	No	Comparison rows in input order — one per distinct barcode whose fetch completed, whether or not a record exists. Barcodes whose fetch failed have no row here; they appear in failed. Barcodes past the cap appear in unprocessed.
`not_found`	No	Barcodes Open Food Facts answered for, confirming no contributor record exists. Not an error — the product may exist but not yet be entered. Never used for a fetch that failed.
`succeeded`	No	Number of barcodes that resolved to a found product.
`unprocessed`	No	Distinct barcodes past the 10th, in input order — never fetched, so nothing is known about them. Absent when the batch held 10 or fewer distinct barcodes. Compare them in another off_compare_products call (2–10 barcodes), or look a single one up with off_get_product.

TDQS

A4.4/5.0

Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Beyond the read-only/idempotent annotations, the description discloses substantial behavior: duplicate barcodes collapse to one row, barcodes past the 10th distinct are listed in unprocessed rather than fetched, missing nutrition is preserved as absent rather than imputed, and failures are partitioned into not_found vs failed. It also explains the prepared-product object and regional scoring caveats, which are exactly the operational details an agent needs.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The core purpose is front-loaded and most sentences carry useful behavioral nuance. It is longer than average, but the density of genuinely relevant details (partial results, preparation state, license) keeps it from being bloated; some barcode-cap wording duplicates the schema.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the multi-product complexity, partial-failure semantics, prepared-state handling, and scoring caveats, the description is complete enough for correct invocation. An output schema exists, so the description need not explain return structure, and it still usefully summarizes the returned columns.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% and the single barcodes parameter already documents deduplication, the 10-distinct cap, and unprocessed overflow. The description restates those semantics in prose but adds no syntax or constraint detail beyond the schema, so baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description opens with a specific verb+resource+scope: 'Side-by-side nutrition and scoring comparison for 2–10 products per call by barcode.' It clearly distinguishes this multi-product comparison tool from single-product siblings like off_get_product and discovery tools like off_search_products.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It names concrete workflows ('which of these cereals is healthiest?', 'compare these pasta brands') that tell an agent when this tool fits. It does not explicitly name alternatives such as off_get_product for single-product lookups or state exclusions, so it falls short of a 5.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
