What it does

Identity Federation is an agent skill from sickn33/agentic-awesome-skills. Authorized assessment of federated identity systems: SAML, OIDC, OAuth2 flows, SSO misconfiguration, and token-confusion issues.

Its SKILL.md is about 620 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/sso-flow-checklist.md`).

It sits in Backend & APIs, covering OAuth and OpenID Connect and Authentication. The repository describes itself as: AAS Core is the local, agent-first control plane for complete catalog discovery, agent-owned selection, stack validation, and planning, backed by 2,400+ agentic skills. Includes… The licence is MIT.

What it can do on your machine

Read from SKILL.md and the folder at commit b84d35a. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
- github.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Identity Federation loads about 617 tokens when it runs, and up to ~677 if it reads all its reference files. Until then it costs about 37 tokens; SKILL.md has 236 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~37
When it runs · the whole SKILL.md, loaded when a task matches: ~617
With references · SKILL.md plus every file in references/, read only if the agent opens them: ~677

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

⚠️ AUTHORIZED USE ONLY This skill is for educational purposes or authorized security assessments only. You must have explicit, written permission from the system owner before using this tool. Misuse of this tool is illegal and strictly prohibited.

Mandatory confirmation gate Before running any command that probes, exploits, changes, persists on, extracts data from, or attempts credential access against a target:

Ask the user to state the exact target URL, IP, account, or resource.

Ask the user to confirm written authorization and the permitted scope.

Show the exact command(s) and explain their expected effect.

Wait for explicit confirmation in the current conversation.

Without that confirmation, remain read-only and provide defensive guidance only. Prefer a sandbox, disposable VM, or controlled lab.

Identity Federation (SAML / OIDC / OAuth)

When to Use

Testing SSO/federation flows within an approved scope.
Hunting signature-validation or audience-confusion flaws.

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-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

Limitations

IdP-side testing is often out of scope; confirm boundaries first.
Token replay tests can lock out real users; stage carefully.
