Better Auth

secondsky/claude-skills
392 installs204 stars
Summary

This drops Better Auth into Claude Code projects when you need authentication that actually works with Cloudflare D1 and modern TypeScript stacks. It's built for self-hosting across 15+ frameworks (Next.js, Nuxt, Workers, Remix) and includes OAuth, 2FA, passkeys, RBAC, and multi-tenant setups. The skill prevents about 20 common errors, mostly around D1 adapter confusion (there's no d1Adapter, you use Drizzle or pass the binding directly in v1.5+) and ESM-only requirements since v1.4. It's a solid Clerk alternative if you want control over your auth stack. The documentation makes migration straightforward, and the new CLI tools in v1.5 handle schema generation and upgrades cleanly.

stardust

adobe/skills

Guided multi-page redesign of an existing website through a four-phase pipeline — extract (crawl and capture the current site), direct (set a visual direction), prototype (generate redesigned HTML), and migrate (emit a deployable static site). Tracks progress incrementally per page in stardust/state.json so redesigns are resumable. Delegates the per-page design craft (typography, spacing, color, layout, motion) to the impeccable skill. Use when the user wants to redesign, revamp, modernize, or restyle an existing site they can point to by URL, run the extract/direct/prototype/migrate flow, or resume a multi-page redesign. Not for designing a brand-new site from scratch or one-off single-component edits.
