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 | $0.00023 | $0.00332 |
| Opus 5 | $0.00012 | $0.00166 |
| Sonnet 5 | $0.00005 | $0.00066 |
| Haiku 4.5 | $0.00002 | $0.00033 |
Grade A, and why
auth-implementation-patterns 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 yesterday.
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 auth-implementation-patterns — 2 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
Authentication & Authorization Implementation Patterns
Build secure, scalable authentication and authorization systems using industry-standard patterns and modern best practices.
Use this skill when
- Implementing user authentication systems
- Securing REST or GraphQL APIs
- Adding OAuth2/social login or SSO
- Designing session management or RBAC
- Debugging authentication or authorization issues
Do not use this skill when
- You only need UI copy or login page styling
- The task is infrastructure-only without identity concerns
- You cannot change auth policies or credential storage
Instructions
- Define users, tenants, flows, and threat model constraints.
- Choose auth strategy (session, JWT, OIDC) and token lifecycle.
- Design authorization model and policy enforcement points.
- Plan secrets storage, rotation, logging, and audit requirements.
- If detailed examples are required, open
resources/implementation-playbook.md.
Safety
- Never log secrets, tokens, or credentials.
- Enforce least privilege and secure storage for keys.
Resources
resources/implementation-playbook.mdfor detailed patterns and examples.
Limitations
- Use this skill only when the task clearly matches the scope described above.
- Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
- Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
What ships with it
1 file 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.

auth-implementation-patterns is a skill published in the GitHub repository sendralt/agentic-awesome-skills (1 stars, last pushed 5d ago), licensed MIT. It adds 23 tokens to every session and 332 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to auth-implementation-patterns, differing in 2 lines, and is treated as a copy.
