Does it provide guidance for secure file uploads?

Absolutely. It mandates validation for file types, sizes, and magic bytes, while recommending ActiveStorage and storing files outside the public directory.

How does this skill prevent SQL injection in Rails?

The skill enforces the use of hash conditions and positional placeholders in ActiveRecord queries while strictly forbidding string interpolation for any user-provided input.

When should I activate the Rails Security skill?

You should use it whenever you are building features that touch user input, handling database queries, managing authentication, or executing shell commands.

Can it help with Cross-Site Scripting (XSS)?

Yes, it provides implementation patterns for safe HTML sanitization, Content Security Policy (CSP) configuration, and prevents the use of unsafe methods like .html_safe.
