.agents/skills/security-audit/SKILL.md

security-audit is a skill for Claude Code, Codex from ateeducacion/moodle-playground. It costs 70 tokens per session (2,395 once invoked), scanned A, original, GPL-3.0.

A codebase security-audit guide for finding vulnerabilities in web apps, APIs, services, command-line tools, libraries, and other software.

In plain words
What is it for?
Use it for security reviews, vulnerability checks, or penetration testing of a codebase.
Why use it?
It helps identify security bugs that could be exploited and separates real risks from theoretical concerns.

Which agent this was written for is unclear — body not stored (licence); the path alone says nothing. Also seen: installed under .agents/ (shared by several agents).

This is ateeducacion/moodle-playground's own configuration. It tells Claude Code and Codex how to work on moodle-playground itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything moodle-playground configures →

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-audit 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 4d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (validate-findings.cjs), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

What ships with it

10 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.
