Can this skill help prevent SQL injection?

Yes, it specifically generates and tests SQL injection payloads to ensure your API properly sanitizes inputs and handles database queries securely.

Is this skill suitable for production environments?

Fuzz testing can cause unexpected crashes or data entries; it is best practice to run these tests in a staging or development environment.

Do I need to specify which endpoints to test?

While the skill can explore APIs, providing specific endpoints and parameter context allows it to generate more accurate and effective test suites.

What is the primary purpose of the /fuzz-api command?

The /fuzz-api command triggers an automated testing process that sends unexpected and malformed data to your API to find security flaws and stability issues.

Does it work with any REST API?

Yes, it is designed to test RESTful endpoints by manipulating headers, parameters, and body payloads to uncover edge cases.

セキュリティとテスト

Automates API security audits by injecting malformed inputs and boundary values to identify vulnerabilities, crashes, and input validation failures.

概要

This skill enables developers to conduct rigorous security assessments of REST APIs by simulating malicious attacks and edge-case scenarios through automated fuzz testing. By generating a diverse range of payloads—including SQL injection strings, cross-site scripting (XSS) attempts, and invalid data types—it identifies critical weaknesses like command injection risks and server-side crashes before they reach production. It is an essential tool for developers looking to harden their backend services and ensure robust input validation directly within the Claude Code environment.
