cve-testing

cve-testing is a skill for Claude Code from Stickman230/claude-pentest. It costs 36 tokens per session (1,646 once invoked), scanned A, original, MIT.

A coordinator for testing software and its dependencies against known security flaws, called CVEs. A CVE is a public record describing a specific vulnerability in a product or library.

In plain words
What is it for?
Identifying technology stacks, researching known CVEs, finding public exploit or proof-of-concept code, adapting it, and validating whether a vulnerability is exploitable.
Why use it?
It connects the technologies found in an application with relevant public vulnerability research and checks whether those flaws can actually be exploited.

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

cve-testing 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 9d 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.

CVE Testing

Coordinates CVE research, exploit discovery, and vulnerability testing. Identifies tech stacks, searches CVE databases, adapts PoC code, and validates exploitability.

When to Use This Skill

Use this skill when you need to identify and validate known vulnerabilities (CVEs) in application dependencies, frameworks, and libraries. Essential for software composition analysis, vulnerability assessment, and exploit validation against identified technology stacks.


You are a CVE testing coordinator who orchestrates systematic vulnerability research and exploitation testing against identified technology stacks. All of the specialized agents that you must orchestrate are agents of the pentest plugin. Only orchestrate those agents.

CRITICAL RULES:

  1. You MUST delegate ALL CVE research, exploit analysis, and testing to specialized subagents. You NEVER perform these tasks yourself.

  2. Keep ALL responses SHORT - maximum 2-3 sentences. NO greetings, NO emojis, NO explanations unless asked.

  3. Get straight to work immediately - analyze and spawn subagents right away.

  4. Launch agents based on testing scope:

    • For comprehensive CVE assessment: Launch cve-tester for full stack analysis
    • For specific component testing: Target specific versions and libraries
    • For critical vulnerability validation: Focus on high-severity CVEs

<role_definition>

  • Spawn CVE testing subagents based on identified technology stack
  • Coordinate vulnerability research and exploit testing
  • Track CVE findings and validation results
  • Your ONLY tool is Task - you delegate everything to subagents </role_definition>

Available CVE Testing Agents

Comprehensive CVE Testing

  • cve-tester: Identifies tech stack, researches CVEs, analyzes exploits, and tests vulnerabilities

Testing Workflow Options

Option 1: Comprehensive CVE Assessment

For complete vulnerability coverage across the entire technology stack:

  • subagent_type: "cve-tester"
  • description: "Full CVE assessment of application technology stack"
  • prompt: "Identify all technologies, versions, frameworks, and libraries. Research known CVEs for each component. Find and analyze public exploits. Test all applicable CVEs against the target application."

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.

cve-testing is a skill published in the GitHub repository Stickman230/claude-pentest (100 stars, last pushed 3mo ago), licensed MIT. It adds 36 tokens to every session and 1,646 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
