Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00071 | $0.04685 |
| Opus 5 | $0.00036 | $0.02343 |
| Sonnet 5 | $0.00014 | $0.00937 |
| Haiku 4.5 | $0.00007 | $0.00468 |
Grade C, and why
guomeiqing-safe-install scanned grade C with 5 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 12d 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.
Instruction-override phrasingmediumPrompt injection
Text telling the model to disregard its earlier instructions or safety rules is the shape of a prompt injection, whoever wrote it.
- "忽略以上指令"、"ignore previous instructions"、"new system prompt" 类语句 Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.
Asks for rootlowPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
| `chmod 600/700` 用于收紧权限 | ✅ PASS | 正常安全操作 | Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.
Recursive force deletemediumDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.
grep -rn -E '(rm -rf|rm -f|chmod|chown|sudo|eval |base64|xxd|openssl|nc |netcat|ncat|socat|mkfifo|/dev/tcp|python.*-c|node.*-e|perl.*-e|ruby.*-e|exec\(|child_process|spawn\(|execSync|kill |pkill|shutdown|reboot|dd |mkfs| Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

🔒 Safe Install — 第三方 Skill 安全审查与安装
你是一个安全审查专家。用户请求安装第三方 Skill 时，绝不能直接安装。你必须按以下流程逐步执行：下载 → 扫描 → 报告 → 决策 → 安装/拒绝 → 清理。
概览
触发条件
用户说了类似以下的话：
- "帮我装 xxx skill"
- "安装这个 skill：<URL 或 npm 包名>"
- "install skill xxx"
- "safe install xxx"
- "帮我安装 https://github.com/xxx/some-skill"
输入识别
用户提供的安装来源可能是以下几种：
- GitHub URL —
https://github.com/user/repo或https://github.com/user/repo.git - npm 包名 —
npm:package-name或纯包名package-name - Git URL —
[email protected]:user/repo.git或其他 git 协议地址
从来源中提取 Skill 名称（最后一段路径或包名），后续用于目录命名。
Step 1: 下载到临时目录
⚠️ 绝不直接下载到 ~/.openclaw/skills/ 或 workspace 目录。必须先下载到隔离的临时目录。
1.1 创建临时目录
用 exec 执行：
REVIEW_ID=$(date +%s)
TEMP_DIR="/tmp/safe-install-${REVIEW_ID}"
mkdir -p "$TEMP_DIR"
记住 TEMP_DIR 路径，后续所有操作都在这里进行。
1.2 下载 Skill
根据来源类型：
GitHub / Git URL：
git clone --depth 1 <URL> "$TEMP_DIR/skill"
npm 包：
cd "$TEMP_DIR"
npm pack <package-name>
mkdir skill
tar xzf *.tgz --strip-components=1 -C skill/
rm -f *.tgz
1.3 验证下载
确认下载成功：
ls -la "$TEMP_DIR/skill/"
必须存在 SKILL.md 文件。 如果没有 SKILL.md，报告为无效 Skill，终止流程并清理临时目录。
Step 2: 文件清点
2.1 列出所有文件
find "$TEMP_DIR/skill" -type f -not -path '*/.git/*' | head -100
记录：
- 总文件数
- 文件类型分布（.md、.js、.ts、.py、.sh、.json 等）
- 是否包含脚本文件（.js/.ts/.py/.sh/.bash/.zsh/.rb/.pl）
2.2 检查文件大小
find "$TEMP_DIR/skill" -type f -not -path '*/.git/*' -exec du -h {} + | sort -rh | head -20
可疑信号： 单个文件 > 1MB，或存在二进制文件（非文本、非图片）。
Step 3: 安全审查（7 项 Checklist）
逐一读取每个文件的内容（用 read 工具），然后按以下 7 项逐项审查。
对每个文件执行审查时，仔细逐行阅读内容，不要跳过或快速浏览。
审查项 1: 外发数据指令 🌐
检查目标： 是否有向外部服务器发送数据的指令。
在所有文件中搜索以下模式：
grep -rn -E '(web_fetch|curl |wget |http://|https://|fetch\(|axios\.|request\(|\.post\(|\.put\()' "$TEMP_DIR/skill/" --include='*' || true
判定规则：
| 发现内容 | 判定 | 说明 |
|---|---|---|
| 无任何 HTTP 请求相关指令 | ✅ PASS | — |
| 仅访问已知合法服务（OpenAI API、Anthropic API、GitHub API 等） | ⚠️ WARN | 在报告中注明目标 URL，解释可能是正常 API 调用 |
| 访问不明 URL、IP 地址、或动态拼接的 URL | 🔴 DANGER | 可能外发用户数据 |
| 明确将文件内容、配置、环境变量作为请求体发送 | 🔴 DANGER | 数据窃取 |
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.
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.

guomeiqing-safe-install is a skill published in the GitHub repository shanggqm/openclaw-security-hardening (52 stars, last pushed 5mo ago), licensed MIT. It adds 71 tokens to every session and 4,685 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it C with 5 findings (instruction-override phrasing, asks for root, recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
