Not pinned. Installing fetches whatever the repository holds at the time you run the command.

No human has reviewed this code. The checks below are a static scan of the files at one commit — nobody has run this skill or judged whether it works. A skill runs with whatever access you give your agent, so read the source before you install it.

Automated safety checks

scanned

This skill failed 1 of 6 checks. A failure is not proof of bad intent; it means something in the code needs a human to look at it before you run it.

  • No undeclared network calls: failed

    Contacts 2 hosts that are neither well-known infrastructure nor declared in the skill's frontmatter: api.target.com, target.com.

    Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.

  • Declares what it does: passed

    SKILL.md parses and declares a name and a description.

    SKILL.md exists, its frontmatter parses, and it declares a name and a description.

  • No obfuscated payloads: passed

    No encoded or obfuscated payloads.

    No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.

  • No credential access: passed

    Reads no keys, tokens, keychains or credential files.

    Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.

  • No pipe-to-shell installers: passed

    No pipe-to-shell or download-and-run installers.

    No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

  • Pinned to a commit: passed

    Scanned jthack/ffuf_claude_skill at 50fd4af4d8.

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

About this skill

The ffuf-web-fuzzing skill enables AI agents to perform fast, efficient web fuzzing using the FFUF (Fuzz Faster U Fool) tool. It automates the discovery of hidden directories, files, and parameters by sending crafted HTTP requests to target servers. This capability helps security professionals identify potential entry points and vulnerabilities in web applications.

When to use it

  • Directory Discovery: Map out the structure of a website to find hidden admin panels or backup files.
  • Parameter Fuzzing: Test input fields for unexpected parameters that might lead to IDOR or injection flaws.
  • Vulnerability Scanning: Quickly probe web servers for common misconfigurations before deeper manual testing.
  • Penetration Testing: Automate the initial reconnaissance phase in authorized security assessments.

Key capabilities

  • Integrates with the FFUF command-line tool for high-speed fuzzing operations.
  • Supports various wordlists to target specific file types or directory names.
  • Executes HTTP requests directly against provided URLs.
  • Returns results indicating successful matches based on status codes or response bodies.

Example prompts

  • "Run a directory fuzzing scan on https://example.com using the standard SecLists directory wordlist."
  • "Fuzz the URL parameters of /login to identify any hidden fields that might bypass authentication."
  • "Execute an HTTP fuzzing test against the target IP to discover non-standard ports or services."

Tips & gotchas

Ensure you have explicit authorization before running fuzzing tools on any target, as unauthorized scanning is illegal. Always configure rate limiting if available to avoid overwhelming the target server and causing service disruption.
