security-checklist is a skill for Claude Code, Codex from ArieGoldkin/ai-agent-hub. It costs 45 tokens per session (6,167 once invoked), scanned A, original, MIT.

A security guide covering common protections for web applications, including the OWASP Top 10 list of widely seen application risks. It also covers login access, input validation, sensitive data, compliance, and dependency checks.

In plain words
What is it for?
Auditing applications, adding authentication and authorization, validating input, protecting personal or payment data, checking dependencies, and preparing for security assessments.
Why use it?
It gives developers a checklist for reducing common security weaknesses and preparing for security reviews.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one.

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is import { ContextManager } from '../lib/context/context-manager.js';.

Good fit Auditing applications, adding authentication and authorization, validating input, protecting personal or payment data, checking dependencies, and preparing for security assessments.

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-checklist scanned grade A with 2 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 10d 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.

Security Checklist

Overview

This skill provides comprehensive security guidance for building secure applications. Whether performing a security audit, implementing new features, or hardening existing systems, this framework helps identify and mitigate common vulnerabilities.

When to use this skill:

  • Conducting security audits or reviews
  • Implementing authentication and authorization
  • Validating and sanitizing user input
  • Handling sensitive data (PII, credentials, payment info)
  • Ensuring compliance (GDPR, HIPAA, SOC2)
  • Preparing for security assessments or penetration tests
  • Reviewing third-party dependencies for vulnerabilities

Required Tools

This skill requires the following tools to be installed on your system:

For JavaScript/TypeScript Projects

  • Node.js 18+ with npm
  • Command: npm audit
  • Install: Node.js comes with npm pre-installed

For Python Projects

  • Python 3.8+ with pip
  • pip-audit: Security scanner for Python dependencies
    • Install: pip install pip-audit
    • Command: pip-audit

Optional (Advanced Security Scanning)

  • Semgrep: Static analysis tool

    • Install (macOS): brew install semgrep
    • Install (pip): pip install semgrep
    • Command: semgrep --config=auto .
  • Bandit: Python security linter

    • Install: pip install bandit
    • Command: bandit -r .
  • TruffleHog: Secrets detection

    • Install (macOS): brew install trufflesecurity/trufflehog/trufflehog
    • Install (Go): go install github.com/trufflesecurity/trufflehog/v3@latest
    • Command: trufflehog filesystem .

Installation Verification

# Verify Node.js & npm
node --version
npm --version

# Verify Python & pip
python --version
pip --version

# Verify pip-audit
pip-audit --version

# Verify optional tools
semgrep --version
bandit --version
trufflehog --version

Note: The skill will automatically detect which tools are available and use appropriate commands for your project type.

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.
