security-audit

security-audit is an agent for Claude Code from LeeYudok/agents-scaffold. It costs 85 tokens per session (3,123 once invoked), scanned C, original, MIT.

A security scanner that searches source code and coding-agent configuration for common risks, such as hard-coded secrets, exposed passwords, unsafe SQL, missing authentication, and prompt-injection issues. It reports findings but does not change files.

In plain words
What is it for?
Use it during security reviews to scan code and agent configuration for the listed P0 and P1 issues, while excluding generated and dependency directories.
Why use it?
Security problems can be hidden in ordinary code or in agent settings such as hooks, permissions, and tool connections. An automated scan gives a repeatable first review before a person decides what to fix.

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 C, and why

security-audit scanned grade C with 5 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 15d 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.

Asks for rootlowPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

grep -rn -E "crontab|launchctl|systemctl.*enable|sudo |chown root" .claude/hooks/ 2>/dev/null

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

Reads agent configuration directorieslowAgent snooping

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

가리키는 링크라(#61) `grep -r .claude/` 만으로는 스킬이 빠진다 — `.agents/` 를 함께 넘긴다.

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

Reads MCP configurationlowAgent snooping

mcp.json carries server URLs and auth tokens; reading it lets a mod discover and abuse other integrations.

[ -f .mcp.json ] && grep -nE '"(env|args)"' -A5 .mcp.json | grep -nE "(KEY|TOKEN|SECRET|PASSWORD)\"?\s*:\s*\"[^$\"]{8,}"

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

Recursive force deletemediumDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

for want in ["Read(.env)","Bash(rm -rf *)","Bash(git push --force *)"]:

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

Not a fault in itself. Listed so you know the mod talks to something, and to what.

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 an agent published in the GitHub repository LeeYudok/agents-scaffold (36 stars, last pushed today), licensed MIT. It adds 85 tokens to every session and 3,123 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it C with 5 findings (asks for root, reads agent configuration directories, reads mcp configuration). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
