Using the Claude app rather than Claude Code? You can add a skill there too. How to add it in the app

What does better-auth-best-practices do?

better-auth-best-practices is a Claude skill for adding and configuring Better Auth, a TypeScript auth library. It first matches docs to the installed version from the lockfile, through the Better Auth MCP or llms.txt. Setup runs in six steps: install, set BETTER_AUTH_SECRET and BETTER_AUTH_URL, write auth.ts, add the route handler, run npx auth@latest migrate or generate a Prisma or Drizzle schema, then call GET /api/auth/ok. It lists config options, session storage and cookie cache modes, email flows, hooks, plugin imports such as twoFactor and passkey, client methods, and gotchas like model names versus table names.
