pentester: Skill for Claude Code

.agents/skills/pentester-update-solution/SKILL.md

pentester-update-solution is a skill for Claude Code, Codex from fb0sh/pentester. It costs 29 tokens per session (192 once invoked), scanned A, original, MIT.

A note-taking rule for authorized penetration tests. It keeps engagement-specific findings in a target folder and sends reusable methods to a shared knowledge base.

In plain words
What is it for?
Use it to record notes for one target, sanitize sensitive details, and promote methods that apply to future penetration tests.
Why use it?
It prevents temporary lab notes, verified vulnerabilities, and reusable testing methods from being mixed together. It also reduces the risk of leaving secrets in notes.

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

pentester-update-solution 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 1mo 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 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.
