TDQS
Scored across 21 tools
Most tools have distinct purposes, but some overlap exists between search tools (advancedSearch, searchByBrand, searchByCategory) and allergen check tools (getAllergenCheck, checkMultipleAllergens). However, descriptions clarify differences, making selection manageable.
Tool names follow a consistent verb+noun pattern (e.g., getProductByBarcode, searchByBrand, checkMultipleAllergens). Even longer names like getProductAIQuestions maintain clarity. No mixing of conventions or obscure verbs.
With 21 tools, the set is comprehensive for a food database API. While slightly above typical ideal range, each tool serves a specific function (search, details, scores, allergies, prices, AI insights). No unnecessary redundancy.
The tool set covers key read operations for OpenFoodFacts: search, product details, nutritional scores, allergens, prices, and AI insights. Missing create/update/delete, but that aligns with a read-only public API. Minor gaps like direct nutrient data access are mitigated by analyzeProduct.
