Test it
Using "next-js-better-auth-integration". Plan Better Auth integration for a new App Router project.
Expected outcome:
- Recommended setup sequence for auth configuration, provider setup, and session context.
- Route protection plan for public and private pages.
- Security checklist covering cookies, CSRF, secrets, and rate limiting.
Using "next-js-better-auth-integration". Review my protected route strategy.
Expected outcome:
- Assessment of server-side and client-side session checks.
- Redirect behavior for unauthenticated users.
- Gaps to verify before production release.
Security Audit
SafeReviewed the three static findings in SKILL.md and found no confirmed malicious or unsafe behavior. The flagged lines are descriptive authentication guidance, not executable code, credential access, weak cryptography, or network reconnaissance. No prompt injection attempt or data exfiltration intent was found.

What You Can Build
Add Authentication to a New App
Plan Better Auth setup, session context, and protected pages before writing implementation code.
Review Auth Architecture
Check whether session handling, redirects, token behavior, and cookie settings are covered.
Prepare Implementation Tasks
Convert authentication requirements into focused work items for App Router, middleware, and UI states.
Try These Prompts
Use this skill to outline the Better Auth setup steps for my Next.js App Router project. Include required files, session flow, and environment variables.
Use this skill to design protected route behavior for these pages: dashboard, settings, and billing. Include unauthenticated redirects and session checks.
Use this skill to review my planned Better Auth session strategy. Focus on cookies, JWT expiration, CSRF protection, rate limiting, and secret handling.
Use this skill to create a phased migration plan from custom auth to Better Auth in a Next.js App Router app with social login and protected server components.
Best Practices
- Start with session and provider requirements before changing routes.
- Keep authentication secrets in managed environment variables.
- Test expired sessions, invalid tokens, and unauthenticated access paths.
Avoid
- Do not store session tokens in insecure client-side storage.
- Do not protect pages only with client-side checks.
- Do not ship authentication flows without rate limiting and CSRF review.
