Reverse Skill is a routing package for AI coding agents that selects appropriate reverse-engineering, penetration-testing, and security-research methods and tools for a given target. It is used for tasks involving APKs, binaries, frontend JavaScript, packet captures, CTF challenges, and authorized penetration testing. Its catalogue add-ons provide the skills and instructions that guide these workflows.
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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00035 | $0.00502 |
| Opus 5 | $0.00017 | $0.00251 |
| Sonnet 5 | $0.00007 | $0.00100 |
| Haiku 4.5 | $0.00003 | $0.00050 |
Grade A, and why
identity-federation 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 8d 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
Identity Federation (SAML / OIDC / OAuth)
ACTION REQUIRED（读完后立刻执行）
NOW: 读取 precedent-pentest；SSO 测试账号与 IdP/SP 范围入 scopeNOW: 禁止锁定真实用户账户的暴力尝试NEXT: 抓包工具与文档（元数据 URL）ACT: 协议流映射 → 常见错配 → 验证
适用场景
- SAML Response 签名/断言篡改面（经典缺陷模式）
- OIDC 隐式/授权码 + PKCE 缺失
- redirect_uri / state / nonce 问题
- IdP 与 SP 元数据、多租户 issuer 混淆
- 与
api-securityJWT 攻击互补（本 skill 偏联邦与 SSO 流）
工作流
□ 画清：User → SP → IdP → Token → SP
□ 收集：/.well-known/openid-configuration、SAML metadata
□ 检查：redirect_uri 精确匹配、state 绑定、PKCE
□ 检查：SAML 签名覆盖范围、algorithm 降级
□ 会话固定与登出失效
工具链
| 工具 | 用途 |
|---|---|
| Burp + SAML Raider 等 | 断言编辑（授权） |
| jwt_tool | JWT 段 |
| 浏览器 DevTools | 重定向链 |
| IdP 管理日志 | 审计 |

What ships with it
1 file 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.

identity-federation is a skill published in the GitHub repository zhaoxuya520/reverse-skill (35,595 stars, last pushed 8d ago), licensed MIT. It adds 35 tokens to every session and 502 once invoked, about $0.0002 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 2026-09-03.
