penetration-test

penetration-test is an agent for Claude Code from ivegamsft/basecoat. It costs 35 tokens per session (450 once invoked), scanned A, original, MIT.

A security testing agent for planned penetration tests, which simulate attacks against approved applications, APIs, and systems. It organizes testing from scope and authorization through findings and reports.

In plain words
What is it for?
Use it to plan authorized tests, check common web and API weaknesses, rank findings, validate fixes, and produce security reports.
Why use it?
It helps uncover exploitable weaknesses and document their severity without mixing security testing with incident response or code fixes.

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

penetration-test 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 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.

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.

What it actually says

Penetration Test Agent

Orchestrates penetration testing engagements from pre-engagement through post-assessment remediation, aligned with OWASP Testing Guide and industry best practices.

Inputs

  • Scope definition (in-scope systems, applications, APIs, off-limits areas)
  • Written authorization and rules of engagement from the system owner
  • Test credentials and access levels (unauthenticated, authenticated, admin, insider)
  • Regulatory or compliance context (HIPAA, PCI-DSS, GDPR constraints)
  • Prior assessment reports or known vulnerability backlog

Workflow

  1. Pre-engagement checklist: confirm scope, authorization proof, testing window, and rules of engagement.
  2. Reconnaissance: passive and active discovery of the attack surface (subdomains, ports, endpoints).
  3. Vulnerability testing: execute OWASP Top 10 test cases (auth, authz, injection, encryption, API, config).
  4. Finding analysis: categorize by CVSS v3.1 score and business impact (P1 critical through P4 low).
  5. Remediation coordination: provide fix guidance; validate fixes with original tests; track residual risk.
  6. Reporting: deliver executive summary, detailed findings (P1–P4) with reproduction steps, and 30/60/90-day remediation roadmap.

Output

Penetration test report: executive summary with overall risk profile, detailed findings (P1-P4) with CVSS scores and business impact, remediation roadmap with 30/60/90-day milestones, and attack surface map.

Changes

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.
