pentest

pentest is a skill for Claude Code, Codex from OXI-717/ai-native-toolkit. It costs 160 tokens per session (3,512 once invoked), scanned B, original, MIT.

A black-box security audit of a running web application, performed from outside through HTTP requests. It checks a deployed app for vulnerabilities without inspecting its source code.

In plain words
What is it for?
Use it to audit a website or Telegram mini app, investigate suspected vulnerabilities, or review the security of a deployed application.
Why use it?
It helps find security problems before attackers do, while keeping the review focused on the explicitly named target and a chosen level of testing.

Skill for Claude CodeCodex

Written for Claude Code and Codex: ${CLAUDE_PLUGIN_ROOT variable, but also agents/openai.yaml present. Also seen: names the AskUserQuestion tool; mentions Claude Code; mentions Codex.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

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 B, and why

pentest scanned grade B with 2 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 7d 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.

Cloud metadata endpointmediumServer-side request forgery

One request to 169.254.169.254 can return temporary IAM credentials.

- SSRF via URL parameters (`url=http://169.254.169.254/latest/meta-data/`)

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

How it starts

The opening of the file, as written. The whole thing — 214 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Pentest

Black-box security audit of a running web application, from the outside, via HTTP.

Default language: match the user's request language (Russian or English). Pass --lang ru|en to override. Reports live in {cwd}/pentest-output/{target-slug}-{YYYY-MM-DD}/.

Assumption: the user has authorization from the target's owner. Do not ask for legalese — trust the user. But never run this skill against a target the user hasn't explicitly named.


Workflow

Phase 0 — Scope

Before touching the target, confirm:

  • Target URL — full https://… URL of the deployed app (the mini app entry URL, not t.me/...).
  • Aggression level — default L1. Let the user override:
    • L0 passive: public metadata only, zero probes of the app itself
    • L1 safe (default): single-request probes, read-only, no mutations
    • L2 authorized: mutations on the auditor's own test account (profile updates, intros, etc.)
    • L3 destructive: real injection payloads, cross-tenant access attempts, rate-limit probing without load testing
  • Target type hinttelegram-miniapp | nextjs-vercel | supabase | generic. Auto-detect from headers if not provided.
  • Languageru or en (default: match user's language).
  • Credentials needed? — if the target needs auth to explore (most apps do), ask the user to paste the auth artifact once:
    • Telegram mini apps: the launch URL fragment (https://…/#tgWebAppData=…) captured from DevTools when the app opens
    • Cookie-based apps: a session cookie or token from the user's logged-in session
    • Store it in secrets.txt under the workspace, add .gitignore to exclude it
    • Never include the raw auth artifact in any report file.

Phase 1 — Workspace

slug=$(echo "<target host>" | tr -cd 'a-z0-9-')
day=$(date +%Y-%m-%d)
workdir="${PWD}/pentest-output/${slug}-${day}"
mkdir -p "${workdir}"/{recon,bundle,scripts,findings,fixes}
echo 'secrets.txt
*.local.*
cookies.txt' > "${workdir}/.gitignore"

What ships with it

9 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

pentest is a skill published in the GitHub repository OXI-717/ai-native-toolkit (8 stars, last pushed 14d ago), licensed MIT. It adds 160 tokens to every session and 3,512 once invoked, about $0.0008 per session on Opus 5. A static security scan graded it B with 2 findings (cloud metadata endpoint, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
