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 | $0.00053 | $0.00703 |
| Opus 5.5 | $0.00021 | $0.00281 |
| Sonnet 5.5 | $0.00011 | $0.00141 |
| Haiku 4.5 | $0.00005 | $0.00070 |
Grade A, and why
mainframe-keycloak-sso 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 9d 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.
How it starts
The opening of the file, as written. The whole thing — 64 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Keycloak SSO integration
Deliver working corporate login and its administration flow in the receiving application's conventions. A settings form alone is not a completed integration. Keep the application's established framework, session architecture, design system, roles and localization. This method does not authorize production IAM changes, account linking, deployment or access-policy changes outside the assigned task.
Establish the integration boundary
Inspect existing login/session, users, authorization middleware, settings storage, admin navigation, public origin/proxy configuration and relevant tests. Identify which part already exists before adding a second authentication system. Determine whether the app has a trusted backend/BFF or is a public browser-only client; a browser-only client cannot hold a client secret. Reuse a maintained OIDC library appropriate to that architecture, not hand-written JWT cryptography.
Reuse established policy for JIT provisioning, linking, role precedence, local login and session revocation. Ask only for unresolved access decisions. For new integrations default to disabled SSO, exact group matching and denial when no mapping grants access. Never silently grant a default role or merge accounts.
Read only the references needed for the current part:
- Protocol and identities: callbacks, tokens, account linking, authorization, multi-instance operation and lifecycle.
- Settings and API: storage, secret updates, safe connection diagnostics and configuration transitions.
- Admin and login UX: the required screen, visible states, mapping editor and functional acceptance, in the app's own style.
- Verification: negative cases, browser acceptance and the boundary between mock evidence and an actual Keycloak login.
- Primary sources: current contracts to consult when selecting a library or resolving version-sensitive behavior.
What ships with it
5 files 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.

mainframe-keycloak-sso is a skill published in the GitHub repository CATWILLgh/MAINFRAME (2 stars, last pushed 3d ago), licensed MIT. It adds 53 tokens to every session and 703 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-10-07.
