Does it provide user-friendly error messages?

Yes, a core focus of this skill is providing clear, actionable, and field-specific error messages that help users correct their input quickly.

Can I use this for complex business rules?

Absolutely. It is designed to handle everything from simple data types to complex business constraints, such as date logic or multi-field dependency checks.

Does this skill handle both frontend and backend validation?

Yes, the Global Validation skill provides guidance for implementing consistent, synchronized validation logic on both the client side and the server side.

How does this skill improve application security?

It enforces strict sanitization and allowlisting protocols to proactively prevent common vulnerabilities such as SQL injection and Cross-Site Scripting (XSS).

セキュリティとテスト

Implements robust, full-stack input validation and data sanitization to ensure application security and data integrity.

概要

The Global Validation skill provides a comprehensive framework for managing data integrity across the entire application lifecycle. It enables Claude to implement consistent validation logic for both client-side forms and server-side API endpoints, ensuring all user input is properly sanitized against injection attacks like SQLi and XSS. By standardizing actionable error feedback and using strict allowlist-based filtering, this skill helps developers build secure, resilient, and user-friendly applications that reject malformed data before it reaches the processing layer.
