Deterministic recipe verification for AI agents. Catches hallucinated temperatures, missing techniques, wrong ingredients, and impossible cooking steps — then suggests one-click fixes. Covers 161+ dishes across 5 cuisines. Also checks EU allergen compliance (all 14 Annex II groups), verifies dietary claims (vegan, halal, kosher, gluten-free), and flags safety issues. Verify against Guardian's built-in master specs or your own house recipe. Same input → same verdict, every time. No API key required.
Computed from public signals only — stars, package downloads and how many registries list it. It measures how established a project is, not whether it is safe or right for you.
