security-pen-testing

security-pen-testing is a skill for Claude Code, Codex from ricneves-ai/flowgrammers-skills. It costs 77 tokens per session (3,994 once invoked), scanned A, original, MIT.

A setup workflow for adding Playwright, a browser testing tool, to an existing project. It detects the project's framework and language, creates configuration and example tests, and can prepare continuous integration.

In plain words
What is it for?
Use it to install Playwright, create playwright.config.ts, set up test directories and example tests, and connect the tests to an existing CI system.
Why use it?
Starting browser tests requires coordinating packages, folders, settings, and automated test runs. This gives the project a standard starting structure based on what it finds.

Written for no agent in particular: nothing here depends on one.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is python scripts/vulnerability_scanner.py --target web --scope full.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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

security-pen-testing scanned grade A with 1 finding 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.

Teste de Penetração de Segurança

Skill de testes de segurança ofensivos para encontrar vulnerabilidades antes que os atacantes o façam. Isso NÃO é verificação de conformidade (veja senior-secops) ou redação de políticas de segurança (veja senior-security) — trata-se de descoberta sistemática de vulnerabilidades por meio de testes autorizados.

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.
