What types of vulnerabilities can this skill identify?

The skill is designed to detect SQL injection, Cross-Site Scripting (XSS), command injection, and general input validation failures.

Can I use this skill on production APIs?

While possible, it is highly recommended to run fuzz tests in a staging or development environment as malformed inputs can cause unexpected behavior or crashes.

How does it analyze the results?

It examines HTTP status codes, response bodies for database error strings, and response times to identify potential security leaks or logic flaws.

How do I start a fuzz test with Claude Code?

You can trigger the skill by using the `/fuzz-api` command and specifying the endpoint or parameters you want to analyze for vulnerabilities.

Does it support GraphQL APIs?

This version of the skill is primarily optimized for REST APIs, using standard HTTP methods and parameter injection techniques.

安全与测试

Performs automated fuzz testing on REST APIs to identify security vulnerabilities, input validation failures, and edge-case crashes.

This skill empowers Claude to act as a proactive security auditor by generating and injecting diverse sets of malformed inputs, boundary values, and random payloads into API endpoints. By analyzing real-time responses, it helps developers discover critical vulnerabilities such as SQL injection, XSS, and command injection before they reach production. It is an essential tool for ensuring backend robustness and verifying that input validation logic is implemented correctly across complex services.
