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 | $0.00057 | $0.00690 |
| Opus 5 | $0.00028 | $0.00345 |
| Sonnet 5 | $0.00011 | $0.00138 |
| Haiku 4.5 | $0.00006 | $0.00069 |
Grade A, and why
security-auditor scanned grade A with 1 finding 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 4d 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.
Runs shell commandslowCapability
Expected in a hook, worth knowing in a rule or an instructions file.
Node.js built-in modules only (http, https, fs, path, child_process). No npm install needed. How it starts
The opening of the file, as written. The whole thing — 77 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Security Auditor
Automated security testing tool that probes web applications for vulnerabilities — pen-test-style checks.
Quick Start
# Full audit
security-auditor review https://example.com --source-dir ./myproject --output-dir /tmp/audit
# Individual scans
security-auditor headers https://example.com
security-auditor secrets ./src
security-auditor deps ./project
security-auditor injection https://example.com
security-auditor auth --auth-config auth.json
Commands
headers <url> — HTTP Security Headers
Checks HSTS, CSP, X-Content-Type-Options, X-Frame-Options, Referrer-Policy, Permissions-Policy, CORS headers, Cache-Control, cookie flags. Grades A-F.
injection <url> — Injection Testing
Tests SQL injection, XSS, command injection, path traversal, SSRF, header injection, NoSQL injection. Safe mode by default; --aggressive for deeper testing.
secrets <dir> — Secret Scanner
Regex + entropy-based scanning for API keys (AWS, GCP, OpenAI, Stripe, GitHub, etc.), private keys, passwords, JWTs, connection strings. Add --git to scan git history.
auth --auth-config <file> — Auth Testing
Tests auth bypass (no token, malformed JWT, none-algorithm), IDOR, brute force detection, privilege escalation, HTTP method override.
Auth config format:
{
"baseUrl": "https://api.example.com",
"token": "Bearer eyJ...",
"protectedEndpoints": ["/api/profile"],
"adminEndpoints": ["/api/admin/users"],
"idorEndpoints": ["/api/users/2/data"],
"loginEndpoint": "/api/login",
"loginBody": { "email": "[email protected]", "password": "wrong" }
}
deps <dir> — Dependency Scanner
Runs npm audit, checks outdated packages, license compliance (flags GPL in proprietary projects).
review <url> — Full Audit Orchestrator
Runs all scans and generates a combined report. Options: --quick, --full, --aggressive, --compare DIR.
report <dir> — Report Generator
Aggregates scan results into markdown + JSON with CVSS-like scoring and remediation steps.
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 JansenAnalytics/claudex (5 stars, last pushed 2mo ago), licensed MIT. It adds 57 tokens to every session and 690 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
