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 | $0.00067 | $0.00606 |
| Opus 5 | $0.00034 | $0.00303 |
| Sonnet 5 | $0.00013 | $0.00121 |
| Haiku 4.5 | $0.00007 | $0.00061 |
Grade A, and why
fec-security-review 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 10d 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.
What it actually says
前端安全审查
用途
识别前端代码中的客户端安全风险，并给出可执行修复建议。
流程
- 先确认审查面：用户输入、动态 HTML、URL 跳转、认证态、RBAC、文件上传、支付/删除等敏感操作、第三方脚本和依赖。
- 搜索高危模式：
dangerouslySetInnerHTML、v-html、innerHTML、document.write、动态 script、未校验 redirect、明文 token。 - 按风险类型审查：XSS、CSP、敏感数据、CSRF、依赖、输入校验、文件上传、开放重定向、认证授权和第三方脚本。
- 用边界模型判断责任：客户端只能改善体验和减少误用，鉴权、授权、上传信任和敏感操作必须由服务端最终裁决。
- 高危问题标记为阻塞合并；前端校验只能改善体验，不能作为唯一安全边界。
- 输出分级安全报告；报告格式见 references/report-template.md。
详细参考
- 需要 XSS、CSP、敏感数据、CSRF、依赖和输入校验细节时，加载 references/security-checklist.md。
- 撰写安全审查报告时，加载 references/report-template.md。
约束
- 不要为了方便开发而绕过安全机制。
- 不要依赖前端校验作为唯一安全防线。
- 不要信任任何来自客户端的数据。
- 发现高危问题时必须标记为阻塞合并。
- 与通用代码质量 review 分工：本 skill 关注威胁、攻击面和数据泄露。
- 不把依赖审计结果机械等同为可利用漏洞；需要结合运行路径、暴露面和修复成本判断。
- 不把隐藏按钮、前端路由守卫或本地角色字段当作授权边界；API、SSR loader、server action 和敏感操作必须有服务端裁决。
预期输出
输出 CRITICAL/HIGH/MEDIUM/LOW 分级安全审查报告，每个问题关联具体文件和行号，给出修复建议；报告保存为 reports/security-review-YYYY-MM-DD-HHmmss.md。
What ships with it
2 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.

fec-security-review is a skill published in the GitHub repository bovinphang/frontend-craft (21 stars, last pushed 9d ago), licensed MIT. It adds 67 tokens to every session and 606 once invoked, about $0.0003 per session on Opus 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 2026-08-30.
