An npm text search for "yello" returns only unrelated projects (a WooRank RabbitMQ library, Trello wrappers, Vue/Arco themes). The scoped package @yello/kit exists on npm ("Kit project for common libraries used across yello", last published 2018-12-19, v1.4.9) but carries no repository, homepage or author link tying it to yello.co, so it is NOT claimed as first-party here. Yello ships no public SDK because it ships no public API: integrations are built by its own integration team under a partner agreement. No SDKs pointer is emitted. packages: [] rejected: - name: '@yello/kit' registry: npm version: 1.4.9 published: '2018-12-19' official: false reason: >- Name-only match. No repository, homepage or maintainer evidence links it to Yello, Inc.; claiming it would attribute a stranger's package to this company. searched_registries: - registry: npm query: https://registry.npmjs.org/-/v1/search?text=yello result: no first-party match - registry: pypi result: no first-party match - registry: rubygems result: no first-party match - registry: crates.io result: no first-party match - registry: nuget result: no first-party match - registry: maven-central result: no first-party match - registry: pkg.go.dev result: no first-party match
