Backend Security Coder

The backend-security-coder skill empowers AI agents to generate secure server-side code, focusing on vulnerability prevention and robust architecture. It assists developers in writing Python, JavaScript, or Go backends that integrate essential security protocols like authentication and encryption from the ground up.

When to use it

• Generating API endpoints with built-in rate limiting and input sanitization to prevent injection attacks.
• Creating database connection handlers that enforce parameterized queries and least-privilege access controls.
• Developing serverless functions or microservices that include secure session management and token validation logic.
• Refactoring legacy backend code to address common flaws such as hardcoded secrets or missing HTTPS enforcement.

Key capabilities

• Writes production-ready backend code in multiple languages including Python, Node.js, and Go.
• Implements industry-standard security patterns like OAuth2, JWT handling, and CORS configuration.
• Generates code structures that automatically validate user inputs against known attack vectors.
• Produces modular functions specifically designed to minimize the attack surface of web applications.

Example prompts

• "Create a secure Python Flask API endpoint for user registration that hashes passwords using bcrypt and validates email formats."
• "Write a Node.js middleware function to enforce strict CORS policies and sanitize all incoming JSON payloads."
• "Generate a Go service for handling JWT authentication with proper expiration checks and refresh token rotation logic."

Tips & gotchas

This skill is designed for generating code, not for performing live penetration testing or scanning existing infrastructure. Ensure you review the generated code against your specific compliance requirements before deploying it to production environments.
