Can this skill assist with React frontend security?

Yes, it includes best practices for XSS prevention, such as avoiding dangerouslySetInnerHTML and implementing robust Content Security Policies (CSP).

Does it cover authentication security?

Absolutely, it details secure password hashing with bcrypt, timing-safe token comparisons, and safe JWT/cookie storage strategies using httpOnly and SameSite flags.

How do I use the security audit feature?

The skill includes a detailed checklist covering input/output, authentication, transport layer security, and infrastructure to verify your application's security posture.

How does this skill help with NoSQL injection?

It provides patterns for input validation with Zod/Joi and middleware like express-mongo-sanitize to prevent malicious operator injection in MongoDB queries.
