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 | $0.00045 | $0.00555 |
| Opus 5.5 | $0.00018 | $0.00222 |
| Sonnet 5.5 | $0.00009 | $0.00111 |
| Haiku 4.5 | $0.00005 | $0.00056 |
Grade A, and why
oauth-oidc-misconfiguration 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 1mo 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.
This is a copy
100% identical to oauth-oidc-misconfiguration — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
SKILL: OAuth and OIDC Misconfiguration — Redirects, PKCE, Scopes, and Token Binding
AI LOAD INSTRUCTION: Use this skill when the target uses OAuth 2.0 or OpenID Connect and you need a focused misconfiguration checklist: redirect URI validation, state and nonce handling, PKCE enforcement, token audience, and account binding mistakes.
1. WHEN TO LOAD THIS SKILL
Load when:
- The app supports
Login with Google, GitHub, Microsoft, Okta, or other IdPs - You see
authorize,callback,redirect_uri,code,state,nonce, orcode_challenge - Mobile or SPA clients rely on OAuth or OIDC flows
For token cryptography and JWT header abuse, also load:
2. HIGH-VALUE MISCONFIGURATION CHECKS
| Theme | What to Check |
|---|---|
state handling |
missing, static, predictable, or not bound to user session |
redirect_uri validation |
prefix match, open redirect chaining, path confusion, localhost leftovers |
| PKCE | missing for public clients, code verifier not enforced, downgraded flow |
OIDC nonce |
missing or not validated on ID token return |
| token audience and issuer | weak aud / iss checks, cross-client token reuse |
| account binding | callback binds attacker identity to victim session |
| scope handling | broader scopes granted than the user or client should receive |
3. QUICK TRIAGE
- Map the full flow: authorize, callback, token exchange, logout.
- Replay callback flows with altered
state,nonce, andredirect_uri. - Compare SPA, mobile, and web clients for weaker validation.
- Check whether one provider account can be rebound to another local account.
4. RELATED ROUTES
- CORS or cross-origin token exposure: cors cross origin misconfiguration
- XML federation or enterprise SSO: saml sso assertion attacks
- CSRF-heavy login or binding bugs: csrf cross site request forgery
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.

oauth-oidc-misconfiguration is a skill published in the GitHub repository SecurityTalent/bugskill-ai (13 stars, last pushed 21d ago), licensed MIT. It adds 45 tokens to every session and 555 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 100% identical to oauth-oidc-misconfiguration, differing in 0 lines, and is treated as a copy.
