security-auditor

security-auditor is a skill for Claude Code from curiositech/some_claude_skills. It costs 119 tokens per session (2,196 once invoked), scanned A, original, MIT.

A code-security auditing guide that scans a project for known dependency problems, leaked secrets, and common vulnerabilities such as injection and cross-site scripting.

In plain words
What is it for?
Use it for dependency checks, secret detection, static code analysis, OWASP Top 10 checks, pre-PR reviews, and pre-deployment audits.
Why use it?
It helps find security issues before deployment or code review, while providing remediation guidance and security reports.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.
    Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.

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 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 8d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/detect-secrets.sh, scripts/full-audit.sh, scripts/owasp-check.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Security Auditor

Comprehensive security scanning for codebases. Identifies vulnerabilities before they become incidents. Focuses on actionable findings with remediation guidance.

When to Use

Use for:

  • Pre-deployment security audits
  • Dependency vulnerability scanning
  • Secret/credential leak detection
  • Code-level SAST (Static Application Security Testing)
  • Security posture reports for stakeholders
  • OWASP Top 10 compliance checking
  • Pre-PR security reviews

Do NOT use for:

  • Runtime security (WAF, rate limiting) - use infrastructure tools
  • Network security/firewall rules - use cloud/DevOps skills
  • SOC2/HIPAA/PCI compliance - requires legal/organizational process
  • Penetration testing execution - this is detection, not exploitation

Quick Start

Full Security Audit

# Run comprehensive scan
./scripts/full-audit.sh /path/to/project

# Output: security-report.json + summary

Quick Checks

# Dependency vulnerabilities only
npm audit --json > deps-audit.json

# Secret detection only
./scripts/detect-secrets.sh /path/to/project

# OWASP check specific file
./scripts/owasp-check.py /path/to/file.js

Core Scanning Capabilities

1. Dependency Scanning

Package Manager Command Severity Levels
npm npm audit --json critical, high, moderate, low
yarn yarn audit --json same as npm
pip pip-audit --format json critical, high, medium, low
cargo cargo audit --json same

Decision Tree:

Critical severity found?
├── YES → Block deployment, immediate fix required
│   └── Check if patch available → npm audit fix --force
├── NO → High severity?
    ├── YES → Fix within sprint, document if deferred
    └── NO → Low/Moderate → Track, fix during maintenance

2. Secret Detection

High-Risk Patterns:

  • API keys: /[A-Za-z0-9_]{20,}/ near "key", "api", "secret"
  • AWS credentials: AKIA[0-9A-Z]{16}
  • Private keys: -----BEGIN (RSA|EC|OPENSSH) PRIVATE KEY-----
  • JWT tokens: eyJ[A-Za-z0-9_-]+\.eyJ[A-Za-z0-9_-]+\.[A-Za-z0-9_-]+
  • Connection strings: ://[^:]+:[^@]+@

What ships with it

4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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-auditor is a skill published in the GitHub repository curiositech/some_claude_skills (221 stars, last pushed 5d ago), licensed MIT. It adds 119 tokens to every session and 2,196 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 1 finding (runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
