security-testing

security-testing is a skill for Claude Code, Codex from ocentra/ocentra-enforcer. It costs 62 tokens per session (1,283 once invoked), scanned A, original, MIT.

A security-testing procedure for systems that handle money, payments, or other valuable transfers through infrastructure that cannot be trusted.

In plain words
What is it for?
It helps classify changes, choose required security-test categories, map threats, check invariants, review mechanics, and prepare tooling for continuous integration.
Why use it?
It turns security review into a sequence covering threats, safety conditions, implementation details, and CI checks, while treating AI output as untrusted.

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-testing 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.

How it starts

The opening of the file, as written. The whole thing — 92 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Security Testing (Money-Critical Mandate)

tier: "T3 advisory — no mechanization possible: this SKILL sequences human/agent judgment across
  Track H (h01-h07); it produces no Finding and gates nothing. Mechanized enforcement lives in the
  h01-h07 Rust Validator rows and the profiles/money-critical-security.json profile, not here."
stages: "route -> h01 classify -> h02 required-categories -> h03 threat-map -> h05 invariants -> h06 mechanics -> h07 tooling/CI"
domain: "GENERIC: any system handling money/payments/value behind untrusted infra (Cloudflare/AWS/API
  gateways are NOT security boundaries; internal APIs are hostile). NOT game- or crypto-specific;
  crypto/blockchain is one OPTIONAL instance, never assumed."
doctrine: "AI output is untrusted input. Silence != permission. If a change cannot be proven safe
  under adversarial conditions, it is unsafe. AI cannot waive/simplify/remove tests or downgrade
  security tests to unit tests."
mechanized_home: "profiles/money-critical-security.json (neutral, no branding) + crates/enforcer-security/src/policy_ingest.rs (ingest a project's own spec into that profile shape)"

This SKILL is prose walkthrough, not an enforcement engine. It carries the label above deliberately: nothing in this file emits a Finding, and nothing in this file gates a merge. The T1/T2 mechanized gates live in the Track H Validator rows (crates/enforcer-security/src/rules/*.rs) and the loadable profile (profiles/money-critical-security.json). Use this SKILL to decide WHICH of those gates apply to the change in front of you, in order.

When To Use This

Any change that creates, transfers, modifies, or destroys value; triggers a blockchain instruction; signs a message; computes an economic/reward/credit/ balance/cooldown value; performs a rollback or compensation; depends on time-based state; or touches a kill switch. If unsure whether a unit is money-critical, treat it as money-critical (fail-closed default, doctrine §8.2).

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.

security-testing is a skill published in the GitHub repository ocentra/ocentra-enforcer (0 stars, last pushed 1mo ago), licensed MIT. It adds 62 tokens to every session and 1,283 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
