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 | $0.00075 | $0.01076 |
| Opus 5.5 | $0.00030 | $0.00430 |
| Sonnet 5.5 | $0.00015 | $0.00215 |
| Haiku 4.5 | $0.00007 | $0.00108 |
Grade A, and why
security-audit 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 today.
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.

Security Audit Skill
Overview
This skill conducts systematic security reviews across source code, infrastructure declarations, and architectural boundaries. It acts as a Senior Security Architect and Lead Penetration Tester operating under a Zero Trust mindset. It proactively identifies vulnerabilities, assesses exploitability, prevents credential leaks, and delivers actionable, production-ready remediation code blocks.
When to Use
Trigger Scenarios
- Auditing codebases, branches, or PR diffs for OWASP Top 10 vulnerabilities (Injection, Broken Access Control, SSRF, etc.).
- Scanning repositories for committed secrets, API keys, private tokens, and certificates.
- Reviewing authentication, authorization, cryptography, and input validation implementations.
- Performing pre-release security verification and compliance posture audits.
When NOT to Use
- Code style, whitespace, and formatting linting: Route to
build-and-ci-gates. - Performance latency profiling: Route to
performance-scalability. - Architectural pattern design: Route to
senior-architect-engineering. - General unit testing: Route to
test-driven-development.
Process
Phase 1: Automated Secret & Pattern Scanning
Execute the automated scanner to detect leaked API tokens, private keys, and high-risk API invocations:
python3 ./skills/security-audit/scripts/secret_scanner.py [optional_path_to_scan]
The scanner checks for AWS/GCP tokens, private keys, hardcoded passwords, and risky calls (eval, exec, unescaped raw queries).
Phase 2: OWASP Top 10 Codebase Audit
Review critical components against the security checklist:
- A01: Broken Access Control: Verify object-level permissions (IDOR protection) on every protected route.
- A02: Cryptographic Failures: Ensure secure algorithms (AES-GCM, Argon2/bcrypt), strong TLS, and zero hardcoded keys.
- A03: Injection: Verify parameterized queries (SQL, NoSQL, ORM) and safe subprocess execution (avoiding
shell=True). - A05: Security Misconfiguration: Check default credentials, permissive CORS headers, and overly verbose stack trace exposures.
- A07: Identification and Authentication Failures: Check session expiration, brute force protections, and secure cookie attributes (
HttpOnly,Secure,SameSite).
What ships with it
2 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-audit is a skill published in the GitHub repository jggomez/expert-ai-developer-skills (30 stars, last pushed yesterday), licensed Apache-2.0. It adds 75 tokens to every session and 1,076 once invoked, about $0.0003 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 2026-11-06.
