snr-pentest

snr-pentest is a command for Claude Code from Kin9Zeus/senior-engineer-skills. It costs 31 tokens per session (698 once invoked), scanned A, original, MIT.

An authorised penetration-testing command for checking web applications, APIs, and cloud systems without damaging them. It first requires written permission, exact scope, a test window, and a stop contact.

In plain words
What is it for?
Use it to make a risk-ordered test plan, check routes and access controls, collect non-destructive evidence, write a report, and verify fixes.
Why use it?
It prevents security testing from accidentally targeting systems you do not own or exceeding the agreed limits. It also turns findings into fixes and a later retest.

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

snr-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 2d 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.

Authorised Security Test

Target: $ARGUMENTS

Load the pentest-methodology skill. This command is authorised, scoped, non-destructive testing only.

Step 0 — the gate (do not skip, do not send a packet before it passes)

  1. Ask the user to confirm, in writing in this chat: who owns the target, that they are entitled to authorise testing, the exact scope, the environment (staging preferred), the time window and a stop contact. If it is a third party's system, require the signed RoE (templates/rules-of-engagement.md).
  2. Create scope.txt (format in references/authorization-and-roe.md) with the authorized-by and valid-until lines.
  3. Run bash skills/pentest-methodology/scripts/scope-guard.sh scope.txt <target> before every new host or IP. Exit 1 = refuse; do not probe.

No gate, no active testing. Without it you may only do: static code review of code the user owns, work on a local lab (references/tooling-and-lab.md), or test the user's own localhost.

Step 1 — plan (--plan stops here)

Build a risk-ordered test plan: model assets and attackers → map routes, roles, APIs → list tests by yield (secrets/exposure → access control → authentication → injection → XSS/CSRF → SSRF/uploads → business logic → configuration → infra → supply chain). Specify accounts needed (two per role), rate limits, and what is out of scope.

Step 2 — test

Follow references/web-app-testing.md, references/api-testing.md and references/infra-and-cloud-testing.md. Rules:

  • Synthetic data and your own test accounts only; never real users' data
  • Prove, don't harvest — inert markers, least harmful evidence, no persistence, no pivoting, no DoS, no social engineering
  • Conservative rates; reproduce every finding twice before reporting
  • Stop and call the contact if real personal data is exposed, the system degrades, an out-of-scope asset appears, or the system looks already compromised (then switch to /snr-incident)

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.
