Is this skill specific to a certain framework?

While it is part of the mrp-nextjs repository, the core principles of input validation, sanitization, and secure defaults are applicable to almost any web framework.

Does it provide guidance on data handling?

Yes, it emphasizes minimizing data exposure, avoiding the logging of sensitive information, and treating all user input as hostile by default.

How does this skill help prevent XSS?

It enforces the use of proper encoding and sanitization while strictly discouraging dangerous patterns like dangerouslySetInnerHTML and raw HTML injection.

Does it support Content Security Policy (CSP)?

Yes, it provides guidance on implementing and respecting CSP to restrict unauthorized script and resource execution in the browser.

Can it help with authentication security?

Absolutely, it promotes secure credential storage, recommends HTTP-only cookies over localStorage, and ensures authorization is enforced on the server.

Security & Testing

Enforces rigorous web security standards and prevents common vulnerabilities throughout the software development lifecycle.

The Web Security skill equips Claude with a security-first mindset, ensuring that application development prioritizes safety over convenience. It provides specific guidance on mitigating common risks like XSS and SQL injection by enforcing strict input validation, data sanitization, and secure encoding. By guiding developers through the implementation of robust authentication patterns, Content Security Policies (CSP), and secure data handling, this skill helps minimize the attack surface and ensures that security is baked into the code from the very first line.
