vulnerability-scanner

vulnerability-scanner is a skill for Claude Code, Codex from Lord1Egypt/awesome-skill-forge. It costs 40 tokens per session (690 once invoked), scanned A, original, MIT.

A security-testing guide for websites you own, covering common weaknesses such as SQL injection, exposed network ports, and browser-related misconfigurations.

In plain words
What is it for?
Use it to scan selected ports, test website parameters for SQL injection, and check browser developer tools for security issues.
Why use it?
It helps reveal basic security problems before they are exploited, including services that should not be publicly reachable.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

vulnerability-scanner scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Vulnerability Scanner

This skill provides tools and guidance to perform basic vulnerability assessments on web applications. It focuses on identifying common security weaknesses such as SQL injection, exposed network ports, and misconfigurations discoverable via browser developer tools.

Features

  1. Port Scanning: Identify open ports on a target host to discover potentially exposed services.
  2. SQL Injection Testing: Perform basic tests for SQL injection vulnerabilities on web application parameters.
  3. DevTools Issue Detection: Guide on how to manually check for security-related issues using browser developer tools.

Usage

Step 1: Scan for Open Ports

Use the port_scanner.py script to check for open ports on a target host. This helps in identifying services that might be unintentionally exposed.

python3 /home/ubuntu/skills/vulnerability-scanner/scripts/port_scanner.py <host> <port1> [port2 ...]

Example:

python3 /home/ubuntu/skills/vulnerability-scanner/scripts/port_scanner.py example.com 80 443 22

Step 2: Test for SQL Injection

Employ the sql_injector.py script to perform a basic SQL injection test on a specified URL parameter. This script appends a common SQL injection payload and reports potential vulnerabilities.

python3 /home/ubuntu/skills/vulnerability-scanner/scripts/sql_injector.py <url> <parameter_name>

Example:

python3 /home/ubuntu/skills/vulnerability-scanner/scripts/sql_injector.py https://www.example.com/products search_query

Step 3: Manual DevTools Vulnerability Check

Refer to the devtools_issues.md guide for instructions on how to manually inspect a website using browser developer tools to uncover security misconfigurations or exposed sensitive information.

  • Guide: See /home/ubuntu/skills/vulnerability-scanner/references/devtools_issues.md for detailed steps on checking for exposed API keys, insecure communications, client-side validation bypasses, and more.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
