security-audit

A code security-audit command that checks a codebase for common vulnerabilities and risky configuration choices. It reviews issues such as injection, unsafe file handling, weak access controls, exposed secrets, and insecure dependencies.

In plain words
What is it for?
Use it to review SQL injection, cross-site scripting, request-forgery protection, authentication, authorization, secrets, dependency vulnerabilities, input validation, error exposure, file operations, and rate limiting.
Why use it?
It helps find security problems before attackers or users encounter them and explains how to fix each finding.

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.

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 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.

What it actually says

Audit security for: $ARGUMENTS

Check for:

  1. SQL injection vulnerabilities
  2. XSS in templates/outputs
  3. CSRF protection gaps
  4. Authentication/authorization flaws
  5. Hardcoded secrets or credentials
  6. Insecure dependencies (run npm audit / pip audit)
  7. Input validation gaps
  8. Error information exposure
  9. Insecure file operations
  10. Missing rate limiting

Rate each finding: Critical > High > Medium > Low Provide specific fixes for each vulnerability found.

Changes

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 command published in the GitHub repository AgriciDaniel/claude-code-essentials-vs-code (57 stars, last pushed 4mo ago), licensed MIT. It adds 6 tokens to every session and 118 once invoked, about $0.0000 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.
