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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00021 | $0.00329 |
| Opus 5 | $0.00010 | $0.00164 |
| Sonnet 5 | $0.00004 | $0.00066 |
| Haiku 4.5 | $0.00002 | $0.00033 |
Grade A, and why
security-audit 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 6d 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.

Expected in a hook, worth knowing in a rule or an instructions file.
- Unsanitized input passed to `eval()`, `exec()`, `child_process` What it actually says
Security Audit
Target: $1 (or entire src/ if not specified)
Check for each OWASP Top 10 category:
A01 - Broken Access Control
- Routes missing auth middleware
- Direct object references without ownership check
- Admin endpoints without role check
A02 - Cryptographic Failures
- Hardcoded secrets or keys
- Weak hashing (MD5, SHA1 for passwords)
- HTTP instead of HTTPS for sensitive data
- Sensitive data stored in localStorage
A03 - Injection
- SQL string concatenation (not parameterized queries)
- Unsanitized input passed to
eval(),exec(),child_process - Template injection risks
A04 - Insecure Design
- Missing rate limiting on auth endpoints
- No account lockout after failed attempts
A05 - Security Misconfiguration
- Debug mode enabled in production
- Overly permissive CORS (
*) - Default credentials
A07 - Auth & Session Failures
- Weak JWT validation
- Missing token expiry
- Session not invalidated on logout
Report findings as:
- CRITICAL - immediate action required
- HIGH - fix before next release
- MEDIUM - fix in next sprint
- INFO - best practice recommendation
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 berkcangumusisik/claude-code-practices (10 stars, last pushed 4mo ago), licensed MIT. It adds 21 tokens to every session and 329 once invoked, about $0.0001 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.
