SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill automates the verification of critical backend security patterns, authentication flows, and error handling, ensuring your API and data are protected.

Core Features & Use Cases

  • API Authentication Verification: Ensures protected endpoints correctly implement authentication guards.
  • Secure Password Handling: Verifies the use of timing-safe comparison for password matching.
  • Robust Error Handling: Checks for consistent try-catch blocks and appropriate error responses for Supabase operations.
  • Use Case: After deploying changes to your API routes or authentication library, run this Skill to automatically audit for common security vulnerabilities and ensure proper error handling before they impact users.

Quick Start

Run the verify-backend skill to audit the security of your API routes and authentication logic.

FAQPage Schema
How do I verify backend security patterns and authentication flows in a Next.js application?

To verify backend security patterns in a Next.js application, you can automate checks for API authentication guards, timing-safe password comparisons, and input validation to ensure your endpoints are protected. This process audits critical authentication flows and API routes for compliance with security best practices.

What is the best way to check for proper Supabase error handling in API routes?

The best way to check for proper Supabase error handling is to automate an audit of your API routes, verifying that consistent try-catch blocks and appropriate error responses are implemented for all Supabase operations. This ensures robust error handling across your backend.

Does this automated check verify timing-safe password comparison and cookie security settings?

Yes, this automated check verifies timing-safe password comparison and validates cookie security settings. It audits your authentication logic to ensure password matching is timing-safe and cookie configurations meet security best practices.

When do I need to run an automated audit for API authentication guards?

You need to run an automated audit for API authentication guards after deploying modifications to your API routes, authentication logic, or utility libraries. This ensures continued compliance with security best practices before changes impact users.

Can I use this tool to check input validation and authentication guards for Next.js API routes?

Yes, you can use this tool to check input validation and authentication guards for Next.js API routes. It automatically audits your backend to ensure protected endpoints correctly implement authentication guards and validate incoming input.

Why does my backend security check fail after modifying authentication logic?

Your backend security check may fail after modifying authentication logic because the changes introduced vulnerabilities like missing API authentication guards or improper Supabase error handling. Running an automated audit identifies these specific security pattern deviations.
