skill-security-audit

skill-security-audit is a skill for Claude Code, Codex from cloud99277/KitClaw. It costs 107 tokens per session (634 once invoked), scanned A, original, MIT.

A static security scanner for AI skill directories, which contain reusable instructions and supporting scripts. It checks scripts for exposed credentials, undeclared network access, unsafe file operations, and dependency risks.

In plain words
What is it for?
Use it to audit one skill or an entire skills repository, focus on credential checks, or create a JSON security report covering credentials, network access, permissions, consent, and supply-chain issues.
Why use it?
It helps find security problems before a skill is run or shared, including secrets in code and network behavior that was not documented.

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

skill-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 1mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/audit.py), 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 it actually says

Skill Security Audit — Skill 安全审计

定位

针对 ~/.ai-skills/ 中 skill 目录的安全静态分析工具。

与其他安全 skill 的差异:

Skill 扫描对象 用途
skill-security-audit skill 的 scripts/ 目录 检测凭据泄露、未声明网络请求、权限越界
security-review 任意代码仓库 通用代码安全审查
security-scan .claude/ 配置文件 配置安全扫描

使用方式

# 审计单个 skill
python3 scripts/audit.py ~/.ai-skills/translate

# 审计单个 skill,仅凭据扫描
python3 scripts/audit.py ~/.ai-skills/translate --dimension=credentials

# 审计全仓
python3 scripts/audit.py ~/.ai-skills --all

# 审计全仓,输出 JSON 报告
python3 scripts/audit.py ~/.ai-skills --all --output=report.json

审计维度

维度 严重度 说明
凭据泄露 🔴 Critical scripts/ 中硬编码的 API key/token/password
数据外传 🔴 Critical scripts/ 中未声明的外部 HTTP 请求
网络越界 🟡 High scripts/ 有网络请求但 SKILL.md 未声明
IO 越界 🟡 High IO 契约声明与脚本实际行为不符
Consent 机制 🟠 Medium 使用逆向 API 的 skill 合规性检查
供应链 🟢 Low 列出外部依赖文件

Files

What ships with it

3 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.
