penetration-testing

penetration-testing is a skill for Claude Code, Codex from Miosa-osa/OSA. It costs 40 tokens per session (3,895 once invoked), scanned D, original, no licence file.

A guide for authorized security testing that checks networks, websites, APIs, and computers for weaknesses, then demonstrates what an attacker could do and records the results.

In plain words
What is it for?
Use it to plan reconnaissance, find and verify vulnerabilities, test what access they allow, examine what could happen afterward, and prepare a penetration-test report.
Why use it?
It gives security reviews a clear path from finding possible problems to confirming their impact and documenting them. It is intended for systems you have permission to test.

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 D, and why

penetration-testing scanned grade D with 3 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.

Suppressing the ability to decline removes a core safety control; a later harmful request then succeeds.

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

penetration-testing is a skill published in the GitHub repository Miosa-osa/OSA (53 stars, last pushed today), with no licence file. It adds 40 tokens to every session and 3,895 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it D with 3 findings (tells the agent never to refuse, cloud metadata endpoint, recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
