Field notes
The homepage demonstrates a Claude Code session searching for a Next.js and Supabase recipe, fetching four files, and displaying the associated test receipt. That receipt includes pinned dependency versions, Node v22.23.3, a 3/3 pass, and a last-passed time; the page links to a GitHub Actions run. The index reports 515 passing recipes across 610 pinned libraries, with TypeScript and Python listed as supported languages.
