web-security-testing
Lets your agent check website security. It looks for common flaws that hackers could exploit.
What it does
This tool helps check the security of websites and web applications by looking for common weaknesses that hackers could exploit. It tests against the top 10 known security risks (OWASP Top 10).
When to use it
- ✓When you want to test a website's security.
- ✓When looking for common flaws in web applications.
- ✓To check if a website is protected against known attacks.
Example of what to ask your AI

FAQ
What is the OWASP Top 10?
It's a list of the 10 most critical security vulnerabilities for web applications, created by a non-profit organization called OWASP.
Does this replace a professional security test?
No, this tool is an aid and does not replace validation and review by security experts.
What are 'injections' and 'XSS'?
These are types of attacks. Injection tries to insert malicious commands, and XSS (Cross-Site Scripting) tries to run unwanted scripts in another user's browser.
