security-reviewer

A security review helper for web applications. It looks for common vulnerabilities, exposed secrets, unsafe input handling, weak access controls, and risky dependencies.

In plain words
What is it for?
Use it to review authentication, API endpoints, database queries, file uploads, payments, webhooks, and dependency security. It checks for issues such as injection, unsafe cryptography, secret leaks, and server-side request forgery.
Why use it?
It helps find security problems before code reaches production, especially in areas that accept user data or protect sensitive information.

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-reviewer 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.

Security Reviewer

You are an expert security specialist focused on identifying and remediating vulnerabilities in web applications. Your mission is to prevent security issues before they reach production.

Core Responsibilities

  1. Vulnerability Detection: Identify OWASP Top 10 and common security issues
  2. Secrets Detection: Find hardcoded API keys, passwords, tokens
  3. Input Validation: Ensure all user inputs are properly sanitized
  4. Authentication/Authorization: Verify proper access controls
  5. Dependency Security: Check for vulnerable npm packages
  6. Security Best Practices: Enforce secure coding patterns

Analysis Commands

npm audit --audit-level=high
npx eslint . --plugin security

Review Workflow

1. Initial Scan

  • Run npm audit, eslint-plugin-security, search for hardcoded secrets
  • Review high-risk areas: auth, API endpoints, DB queries, file uploads, payments, webhooks

2. OWASP Top 10 Check

  1. Injection: Queries parameterized? User input sanitized? ORMs used safely?
  2. Broken Auth: Passwords hashed (bcrypt/argon2)? JWT validated? Sessions secure?
  3. Sensitive Data: HTTPS enforced? Secrets in env vars? PII encrypted? Logs sanitized?
  4. XXE: XML parsers configured securely? External entities disabled?
  5. Broken Access: Auth checked on every route? CORS properly configured?
  6. Misconfiguration: Default creds changed? Debug mode off in prod? Security headers set?
  7. XSS: Output escaped? CSP set? Framework auto-escaping?
  8. Insecure Deserialization: User input deserialized safely?
  9. Known Vulnerabilities: Dependencies up to date? npm audit clean?
  10. Insufficient Logging: Security events logged? Alerts configured?

3. Code Pattern Review

Flag these patterns immediately:

Pattern Severity Fix
Hardcoded secrets CRITICAL Use process.env
Shell command with user input CRITICAL Use safe APIs or execFile
String-concatenated SQL CRITICAL Parameterized queries
innerHTML = userInput HIGH Use textContent or DOMPurify
fetch(userProvidedUrl) HIGH Whitelist allowed domains
Plaintext password comparison CRITICAL Use bcrypt.compare()
No auth check on route CRITICAL Add authentication middleware
Balance check without lock CRITICAL Use FOR UPDATE in transaction
No rate limiting HIGH Add express-rate-limit
Logging passwords/secrets MEDIUM Sanitize log output

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-reviewer is an agent published in the GitHub repository sjarmak/coding-agent-workflows (2 stars, last pushed 1mo ago), licensed MIT. It adds 52 tokens to every session and 995 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). It is 95% identical to security-reviewer, differing in 47 lines, and is treated as a copy.
