SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Unvalidated or poorly validated user input is a major source of security vulnerabilities (e.g., SQL injection, XSS) and data integrity issues. This Skill ensures robust validation, protecting your application and data.

Core Features & Use Cases

  • Client/Server-Side Validation: Implement validation at both frontend and backend for security and user feedback.
  • Input Sanitization: Clean user input to prevent injection attacks and malicious data.
  • Allowlists over Blocklists: Define acceptable input explicitly rather than trying to block all bad input.
  • Use Case: When creating a user registration form, use this Skill to implement both client-side (for immediate feedback) and server-side (for security) validation for email format, password strength, and required fields.

Quick Start

Implement comprehensive validation for the new user profile update endpoint, ensuring email format, age range (18-99), and sanitizing all text inputs.
