identity-federation

identity-federation is a skill for Claude Code, Codex from xAmirHamza77/ReverseOps-Skill. It costs 35 tokens per session (475 once invoked), scanned A, original, MIT.

A guide to reviewing SAML, OpenID Connect, and OAuth, which are standards used for single sign-on and delegated access. It focuses on how identity providers, applications, redirects, and tokens interact.

In plain words
What is it for?
Use it to map SSO flows, inspect metadata, check signatures and PKCE, and test redirect, session, logout, and issuer handling.
Why use it?
It helps find configuration mistakes that can let attackers alter login responses, misuse redirects, or confuse tokens and sessions.

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.

Fable 5.1 $0.00035 $0.00475
Opus 5 $0.00017 $0.00237

Security

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 6d 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execute)

  1. NOW: read precedent-pentest;SSO Testing账号与 IdP/SP scope入 scope
  2. NOW: forbidden锁定真实用户账户的暴力尝试
  3. NEXT: packet capturetool与documentation(元数据 URL)
  4. ACT: protocol流映射 → 常见错配 → 验证

Use Cases

  • SAML Response signature/断言篡改面(经典缺陷模式)
  • OIDC 隐式/authorization码 + PKCE 缺失
  • redirect_uri / state / nonce 问题
  • IdP 与 SP 元数据、多租户 issuer obfuscation
  • api-security JWT 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match、state 绑定、PKCE
□ 检查:SAML signature覆盖scope、algorithm 降级
□ session固定与登出失效

Toolchain

IdP 管理log 审计

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.
