PentestGPT: Skill for Claude Code

.agents/skills/grilling/SKILL.md

grilling is a skill for Claude Code, Codex from GreyDGL/PentestGPT. It costs 36 tokens per session (127 once invoked), scanned A, original, MIT.

A structured interview for stress-testing a software plan or design before implementation.

In plain words
What is it for?
Use it to examine a plan one decision at a time, with recommended answers and codebase exploration where that can resolve a question.
Why use it?
It reveals unanswered decisions and dependencies through focused questions, reducing the chance of building on unclear assumptions.

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

This is GreyDGL/PentestGPT's own configuration. It tells Claude Code and Codex how to work on PentestGPT 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 PentestGPT configures →

About the project

PentestGPT is an AI-driven framework for penetration testing and capture-the-flag challenges. It guides staged workflows such as reconnaissance, asset discovery, vulnerability identification, exploitation, and reporting, using large language models to operate tools and reason about findings. The catalogue includes skills and instructions for using it.

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

grilling 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 it actually says

Interview me relentlessly about every aspect of this plan until we reach a shared understanding. Walk down each branch of the design tree, resolving dependencies between decisions one-by-one. For each question, provide your recommended answer.

Ask the questions one at a time, waiting for feedback on each question before continuing. Asking multiple questions at once is bewildering.

If a question can be answered by exploring the codebase, explore the codebase instead.

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.
