vulnerability-scanning

Lets your agent check systems and programs for security flaws. It identifies known issues that hackers could exploit.

What it does

This tool helps find security flaws in systems and programs. It looks for known vulnerabilities (CVEs) that attackers could exploit.

When to use it

  • ✓When checking the security of a website or network.
  • ✓To ensure a system is protected against known threats.
  • ✓When needing to meet security regulations.

Example of what to ask your AI

“Check if the website example.com has any known vulnerabilities.”

Use this skill to help me: https://github.com/sickn33/agentic-awesome-skills/blob/main/plugins/agentic-awesome-skills-claude/skills/vulnerability-scanning/SKILL.md Read the SKILL.md file at that link and follow its instructions for my task.
How it works

The tool uses specific programs (like Nessus or Nuclei) to test systems against a list of security flaws. It reports which issues were found and their risk level.

Installation

Easiest way: copy the skill link and paste it into Claude, ChatGPT or Cursor asking it to follow the instructions.

In the terminal (Claude Code, Codex, Cursor), in your project folder:

npx skills add sickn33/agentic-awesome-skills --skill vulnerability-scanning

Or download just the file:

curl -L https://raw.githubusercontent.com/sickn33/agentic-awesome-skills/main/plugins/agentic-awesome-skills-claude/skills/vulnerability-scanning/SKILL.md -o SKILL.md

⚠️ AUTHORIZED USE ONLY This skill is for educational purposes or authorized security assessments only. You must have explicit, written permission from the system owner before using this tool. Misuse of this tool is illegal and strictly prohibited.

Mandatory confirmation gate Before running any command that probes, exploits, changes, persists on, extracts data from, or attempts credential access against a target:

  1. Ask the user to state the exact target URL, IP, account, or resource.
  2. Ask the user to confirm written authorization and the permitted scope.
  3. Show the exact command(s) and explain their expected effect.
  4. Wait for explicit confirmation in the current conversation.

Without that confirmation, remain read-only and provide defensive guidance only. Prefer a sandbox, disposable VM, or controlled lab.

Vulnerability Scanning

Identify and prioritize security vulnerabilities across infrastructure and applications.

  • Performing security assessments
  • Implementing vulnerability management programs
  • Meeting compliance requirements
  • Triaging and prioritizing remediation
  • Scanning infrastructure for known CVEs

Prerequisites

  • Access to scanning tools
  • Network access to targets
