What it does
Handles server/client authentication boundaries using @supabase/ssr, protecting routes via middleware and managing cookie-based sessions
Provides patterns for OAuth callbacks, Server Actions for auth operations, and proper token handling across Server and Client Components
Includes anti-patterns to avoid: getSession in Server Components, unlistened client auth state, and manual token storage
Installation Guide
How to use nextjs-supabase-auth on Cursor
AI-first code editor with Composer
Prerequisites
Before installing skills in Cursor, ensure your development environment meets these requirements:
- ›Cursor installed and configured on your machine
- ›Node.js 16+ with npm — verify with
node --version - ›Active project directory where you want to add
nextjs-supabase-auth
Run the install command
Execute the skills CLI command in your project's root directory to begin installation:
Fetches nextjs-supabase-auth from sickn33/antigravity-awesome-skills and configures it for Cursor.
Select Cursor when prompted
The CLI shows a list of agents. Use arrow keys and space to select Cursor:
Verify installation
Confirm successful installation by checking the skill directory location:
Restart Cursor to activate nextjs-supabase-auth. Access via /nextjs-supabase-auth in your agent's command palette.
Security Notice
We perform automated surface-level scans (Gen AI Scanner, Socket, Snyk) during installation. These checks detect common vulnerabilities but do not guarantee complete security. Always review skill source code and verify the publisher's reputation before production use.
Skills execute code in your environment. Always review source, verify the publisher, and test in isolation before production.

Next.js + Supabase Auth
You are an expert in integrating Supabase Auth with Next.js App Router. You understand the server/client boundary, how to handle auth in middleware, Server Components, Client Components, and Server Actions.
Your core principles:
- Use @supabase/ssr for App Router integration
- Handle tokens in middleware for protected routes
- Never expose auth tokens to client unnecessarily
- Use Server Actions for auth operations when possible
- Understand the cookie-based session flow

- 5Integrate into regular workflow if valuable
Common Pitfalls
- ⚠Expecting perfect results without iteration
- ⚠Not providing enough context in prompts
- ⚠Using skill for tasks outside its intended scope
- ⚠Accepting outputs without review and validation
Best Practices
✓ Do
- +Start with clear, specific prompts
- +Provide relevant context and constraints
- +Review and refine all outputs before using
- +Iterate to improve output quality
- +Document successful prompt patterns
✗ Don't
- −Don't use without understanding skill limitations
- −Don't skip validation of outputs
- −Don't share sensitive information in prompts
- −Don't expect skill to replace human judgment
💡 Pro Tips
- ★Be specific about desired format and style
- ★Ask for multiple options to choose from
- ★Request explanations to understand reasoning
- ★Combine AI efficiency with human expertise
When to Use This
✓ Use when
Use when skill capabilities match your task, clear ROI on time saved, and you can validate outputs. Best for repetitive tasks, learning, and quality improvement.
✗ Avoid when
Avoid when task requires deep expertise you can't validate, involves sensitive decisions, or when learning process is more valuable than speed of completion.
Learning Path
- 1Familiarize yourself with skill capabilities and limitations
- 2Start with low-risk, non-critical tasks
- 3Progress to more complex and valuable use cases
- 4Build expertise through regular use and experimentation
