pentest-validation

pentest-validation is a skill for Claude Code from summarybotng/summarybot-ng. It costs 57 tokens per session (2,595 once invoked), scanned B, original, MIT.

A security-finding validation workflow that checks whether reported weaknesses can actually be exploited. It combines code and dependency scanning, code review, controlled testing, and evidence-based reporting.

In plain words
What is it for?
Validating security findings, testing suspected vulnerabilities, producing proof-of-concept evidence, and recording exploitation attempts.
Why use it?
It helps filter out false alarms by requiring proof that a weakness is exploitable before reporting it. It also requires authorization and keeps testing within development or staging environments.

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 B, and why

pentest-validation scanned grade B with 1 finding 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 5d 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.

Cloud metadata endpointmediumServer-side request forgery

One request to 169.254.169.254 can return temporary IAM credentials.

| Internal URL | User-controlled URL fetch | `http://169.254.169.254` | Cloud metadata extraction |

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Pentest Validation

<default_to_action> When validating security findings:

  1. REQUIRE explicit authorization for target URL
  2. SCAN with qe-security-scanner (SAST + dependency + secrets)
  3. ANALYZE with qe-security-reviewer + qe-security-auditor (parallel)
  4. VALIDATE with qe-pentest-validator (graduated exploitation, parallel per vuln type)
  5. REPORT only confirmed findings with PoC evidence ("No Exploit, No Report")
  6. UPDATE exploit playbook with new patterns

Quality Gates:

  • Authorization confirmed before ANY exploitation
  • Target URL is staging/dev (NOT production)
  • Budget cap enforced ($15 default)
  • Time cap enforced (30 min default)
  • All exploitation attempts logged </default_to_action>

Quick Reference Card

The 4-Phase Pipeline

Phase Agent(s) Purpose Parallelism

3. Validation qe-pentest-validator Graduated exploit validation Per-vuln-type parallel
4. Report qe-quality-gate "No Exploit, No Report" filter Sequential

What this file has done since we first saw it

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.
