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 | $0.00062 | $0.00745 |
| Opus 5 | $0.00031 | $0.00373 |
| Sonnet 5 | $0.00012 | $0.00149 |
| Haiku 4.5 | $0.00006 | $0.00075 |
Grade A, and why
security-misconfiguration 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 2d 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.

Security Misconfiguration Security Check (A02:2025)
What this checks
Protects against insecure defaults, overly permissive policies, and missing hardening that expose the application to cross-origin attacks, credential stuffing, and information disclosure via error pages or debug endpoints.
Vulnerable patterns
- Wildcard CORS origin combined with credentials enabled — every site on the web gets cookie-authenticated access
- Debug or verbose-error mode hardcoded on, exposing tracebacks, route lists, or interactive consoles in production
- Wildcard or empty host/origin allowlist accepted in production configuration
- HTTP server with no security-headers layer registered —
Strict-Transport-Security,X-Content-Type-Options, and a framing/CSP control missing. For hardcoded secrets seehardcoded-secrets.
Fix immediately
Flag the vulnerable code, explain the risk, and suggest a fix establishing these properties. Translate to the language and framework of the audited file — use that stack's documented middleware or configuration helpers; do not import recipes from a different stack.
- CORS that allows credentials uses an explicit origin allowlist. Never a wildcard, never a reflected
Originheader. Browsers block wildcard-plus-credentials in spec, but misconfigured middleware still ships it. - Debug and verbose-error flags default to off in production. Their values are sourced from environment or config, not hardcoded on. A production-only assertion that fails loudly when debug is left enabled catches misconfigured deploys.
- Every HTTP server registers a security-headers layer before routes. Baseline:
Strict-Transport-Security,X-Content-Type-Options: nosniff, and a framing or CSP control. An upstream proxy may own these instead — but only if that ownership is documented at the call site. - Host and origin validation uses an explicit allowlist, never a wildcard or an empty default. Trusted-origin and CSRF-trusted-origin lists are attacker-reachable when unset.
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-misconfiguration is a skill published in the GitHub repository thejefflarson/soundcheck (20 stars, last pushed 1mo ago), licensed MIT. It adds 62 tokens to every session and 745 once invoked, about $0.0003 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.
