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 | $0.00029 | $0.00506 |
| Opus 5.5 | $0.00012 | $0.00202 |
| Sonnet 5.5 | $0.00006 | $0.00101 |
| Haiku 4.5 | $0.00003 | $0.00051 |
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 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.
What it actually says
Security & OWASP Analysis
Security 🔒 specialist pass.
Data Sources
Visual + accessibility-tree analysis (browser_snapshot, browser_take_screenshot):
- Input fields without visible validation
- URLs containing sensitive parameters
- Forms without CSRF tokens (no hidden token field in the snapshot)
- Mixed HTTP/HTTPS content
- Clickjacking risk (missing X-Frame-Options — see network data below)
Network data (browser_network_requests, browser_console_messages(level:"error") from
the Step-0 collection):
- Failed/erroring security-related requests
- Response headers (CSP, X-Frame-Options, HSTS, etc. — see the header table below)
Focus Areas
Look for:
- XSS vectors in forms/URLs (unescaped user input rendering)
- CSRF vulnerabilities (forms without tokens)
- Insecure HTTP resources on HTTPS pages (mixed content)
- Exposed sensitive data in URLs (tokens, passwords, PII)
- Weak password policies (no length/complexity requirements)
- Missing security headers (CSP, X-Frame-Options, HSTS)
- Clickjacking risks (pages embeddable in iframes)
- Open redirects (redirect parameters in URLs)
- Input validation gaps
- Exposed API keys or tokens in page source/network
OWASP Top 10 Quick Check
See references/owasp-checklist.md for detailed criteria.
| OWASP | What to look for |
|---|---|
| A01 Broken Access | Direct object references, missing auth checks |
| A02 Crypto Failures | HTTP, sensitive data in localStorage |
| A03 Injection | Unparameterized inputs, reflected URL params |
| A05 Misconfiguration | Verbose error pages, default credentials |
| A07 Auth Failures | No rate limiting, weak password policy |
Output
Security findings default to p0-p1 unless informational (p3). Produce findings
in the shared schema — see the qa-auditor audit-methodology.md.

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.

security-audit is a skill published in the GitHub repository arozumenko/sdlc-skills (25 stars, last pushed yesterday), licensed MIT. It adds 29 tokens to every session and 506 once invoked, about $0.0001 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 2026-08-30.
