security-audit

A security review process for Rust projects that checks code, dependencies, secrets, access controls, and input handling.

In plain words
What is it for?
Use it to review dependency advisories, unsafe code, secret exposure, injection risks, cryptography, authentication, authorisation, denial-of-service risks, and software supply-chain trust.
Why use it?
It helps find weaknesses that could expose data, allow unwanted access, accept unsafe input, or make the program fail under attack.

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-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 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.

Unrestricted tool accesslowExcessive agency

A wildcard tool grant or "run any command" leaves no least-privilege boundary at all.

**`build.rs` scrutiny** — build scripts run arbitrary code on the developer's and CI machine with full permissions. Review every dependency's `build.rs` that does network I/O, shells out, or reads outside `OUT_DIR`. A ma

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

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 bug-ops/claude-plugins (11 stars, last pushed 7d ago), with no licence file. It adds 90 tokens to every session and 3,882 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 1 finding (unrestricted tool access). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
