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.

What it costs to keep this loaded
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 | $0.00030 | $0.00905 |
| Opus 5 | $0.00015 | $0.00452 |
| Sonnet 5 | $0.00006 | $0.00181 |
| Haiku 4.5 | $0.00003 | $0.00090 |
Grade A, and why
security-auditor 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 — 124 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Security Auditor
Expert in identifying security vulnerabilities following OWASP Top 10 and security best practices.
When This Skill Activates
Activates when you:
- Request a security audit
- Mention "security" or "vulnerability"
- Need security review
- Ask about OWASP
OWASP Top 10:2025 Coverage
Use the current OWASP Top 10 as an awareness taxonomy, not as proof of complete security coverage. For verifiable application controls, map findings to the current OWASP ASVS or the project's required standard.
A01: Broken Access Control
- Verify authentication and object/function-level authorization on every sensitive path.
- Test tenant boundaries, IDOR/BOLA, role changes, and server-side URL fetch controls.
- SSRF is included in this 2025 category; validate destinations, schemes, redirects, and network egress.
A02: Security Misconfiguration
- Inspect debug flags, CORS, security headers, default accounts, cloud/IaC policy, and error exposure.
- Compare runtime configuration with hardened environment-specific defaults.
A03: Software Supply Chain Failures
- Review lockfiles, provenance, build workflows, mutable CI dependencies, update policy, and dependency risk.
- Distinguish a vulnerable package from compromised build or distribution infrastructure.
A04: Cryptographic Failures
- Check secret storage, transport encryption, key lifecycle, random generation, algorithms, and data-at-rest requirements.
- Flag hardcoded credentials, weak hashes, insecure modes, and missing certificate verification.
A05: Injection
- Trace untrusted data into SQL/NoSQL, shell, template, LDAP, expression, and browser execution sinks.
- Prefer parameterization and safe APIs; test encoding at the actual output context.
A06: Insecure Design
- Threat-model trust boundaries, abuse cases, rate limits, high-risk workflows, and failure recovery.
- Verify the design prevents unsafe states rather than relying only on downstream validation.
A07: Authentication Failures
What ships with it
6 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.

security-auditor is a skill published in the GitHub repository zhaono1/agent-playbook (77 stars, last pushed 14d ago), licensed MIT. It adds 30 tokens to every session and 905 once invoked, about $0.0002 per session on Opus 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 2026-08-30.
