web-pentest

web-pentest is a skill for Claude Code, Codex from Unclecheng-li/DeepSec. It costs 43 tokens per session (477 once invoked), scanned A, a copy of web-pentest, MIT.

A workflow guide for testing the security of web applications, which are websites and online services that accept requests and return pages or data. It covers discovery, login and session checks, input handling, and business rules.

In plain words
What is it for?
Use it for authorized web penetration tests covering technology identification, directory and API discovery, authentication, SQL injection, cross-site scripting, server-side request forgery, file handling, access control, and payment or other business-logic flaws.
Why use it?
It gives a structured way to look for common weaknesses instead of checking only one part of an application. It also describes the expected output, including a security report and proof-of-concept scripts.

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

web-pentest 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.

Origin

This is a copy

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.
