security-auditor

security-auditor is an agent for coding agents from HermeticOrmus/LibreUIUX-Claude-Code. It costs 85 tokens per session (1,875 once invoked), scanned A, original, MIT.

A security auditing specialist for finding weaknesses in applications, infrastructure, dependencies, containers, authentication, and development pipelines. It also covers common security standards and compliance requirements.

In plain words
What is it for?
Use it for vulnerability assessment, threat modelling, secure-code reviews, dependency and container checks, secrets management, authentication reviews, and security automation.
Why use it?
It helps find security problems earlier, before they become breaches or release blockers. It brings security checks into normal software development work.

Token cost

What it costs to keep this loaded

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.

Security

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 yesterday.

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 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.
