Clerk Skills Router

Version Detection

Check package.json to determine the Clerk SDK version. This determines which patterns to use:

Default to current if the version is unclear or the project is new. Core 2 packages use @clerk/clerk-react and @clerk/clerk-expo (with clerk- prefix); current packages use @clerk/react and @clerk/expo.

All skills are written for the current SDK. When something differs in Core 2, it's noted inline with > **Core 2 ONLY (skip if current SDK):** callouts. The exception is clerk-custom-ui, which has separate core-2/ and core-3/ directories for custom flow hooks since those APIs are entirely different between versions.
