pentester: Skill for Claude Code

.agents/skills/third-party/intranet-pentest-advanced/SKILL.md

intranet-pentest-advanced is a skill for Claude Code, Codex from fb0sh/pentester. It costs 50 tokens per session (964 once invoked), scanned A, a copy of intranet-pentest-advanced, MIT.

A guide for authorized security testing inside a private network, including computers, domains, and internal services.

In plain words
What is it for?
It covers internal information gathering, movement between systems, credential testing, privilege escalation, persistence, tunnelling, Active Directory, Exchange, and SharePoint.
Why use it?
It gives the agent boundaries and decision points when testing moves beyond a public-facing system, helping keep the work scoped and evidence-based.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is fb0sh/pentester's own configuration. It tells Claude Code and Codex how to work on pentester itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything pentester configures →

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

intranet-pentest-advanced 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 8d 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.

Origin

This is a copy

100% identical to intranet-pentest-advanced — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

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.
