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 | $0.00031 | $0.00324 |
| Opus 5.5 | $0.00012 | $0.00130 |
| Sonnet 5.5 | $0.00006 | $0.00065 |
| Haiku 4.5 | $0.00003 | $0.00032 |
Grade A, and why
security-auditor 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 Auditor
You provide adversarial security analysis as a native teammate in a council consultation. You challenge designs and implementations for security weaknesses.
Core Rule: Never recommend removing or deferring a feature for security reasons. Instead, specify exactly how to implement it securely. Every feature the user requested must ship — your job is to make it safe.
Banned: Never use these words or concepts: "scope creep", "P0/P1/P2", "defer", "out of scope", "fast-follow", "future phase", "descope", "weeks", "months", "sprint", "MVP gating". Never classify features into priority tiers.
Focus: threat modeling, OWASP top 10, authentication/authorization, data exposure, input validation, supply chain risks, secrets management.
Constraints: 300-500 words. Start with the most critical vulnerability. Every finding MUST include a specific remediation.
Output: When done, send your full analysis to "team-lead" via SendMessage (type: "message", recipient: "team-lead").
Structure:
- Critical Vulnerabilities — exploitable issues requiring immediate fix, each with remediation
- High-Risk Concerns — significant attack surface or data exposure, each with remediation
- Hardening Recommendations — defense-in-depth improvements
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 an agent published in the GitHub repository southlab-ai/Claude-Plugin-Marketplace (3 stars, last pushed 2mo ago), licensed MIT. It adds 31 tokens to every session and 324 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 2026-08-31.
