# 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
- 与 `api-security` JWT 攻击互补(本 skill 偏联邦与 SSO 流)
## 工作流
```text
□ 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
| tool | 用途 |
|------|------|
| Burp + SAML Raider 等 | 断言编辑(authorization) |
| jwt_tool | JWT 段 |
| 浏览器 DevTools | redirect链 |
| IdP 管理log | 审计 |
## 参考
- `references/sso-flow-checklist.md`
- `../api-security/` `../windows-ad/`(企业 IdP)
## routing上下文
**上游**: MASTER R37
**下游**: 纯 API JWT → api-security;云 IdP → cloud-k8s

Ultra-compressed communication mode. Cuts token usage ~75% by speaking like caveman while keeping full technical accuracy. Supports intensity levels: lite, full (default), ultra, wenyan-lite, wenyan-full, wenyan-ultra. Use when user says "caveman mode", "talk like caveman", "use caveman", "less tokens", "be brief", or invokes /caveman. Also auto-triggers when token efficiency is requested.
Adversarial multi-agent planning skill. Self-orchestrates 5 hostile category members (unspecified-low, unspecified-high, deep, ultrabrain, artistry) via team-mode for ruthless cross-critique debate, distills only the defensible insights, then MANDATORILY hands the distilled insight bundle to the `plan` agent for executable plan formalization. Use when planning needs maximum rigor and surfacing of weak assumptions, blind spots, and over-engineering. Triggers: 'hyperplan', 'hpp', '/hyperplan', ...
Routes multi-tool workflows through MCP servers for large datasets and pipelines. Use when Bash tool overhead is limiting throughput on data-heavy tasks.
**Complete production-ready guide for Google Gemini embeddings API** This skill provides comprehensive coverage of the `gemini-embedding-001` model for generating text embeddings, including SDK usage, REST API patterns, batch processing, RAG integration with Cloudflare Vectorize, and advanced use cases like semantic search and document clustering. ---
Recovers prior coding-agent session context by running `catchup <agent> --since-compact`, which extracts a clean summary of a previous Codex, Claude Code, Antigravity, OpenCode, or Pi Agent session. Use when the user says "catch up", "what did the last session do", "get me up to speed", "I switched agents", or asks to recover/summarize a previous session before continuing. Do NOT use for the current conversation, git history, or any non-agent log.
