security-reviewer

security-reviewer is an agent for Claude Code from vibeeval/vibecosystem. It costs 52 tokens per session (3,691 once invoked), scanned A, original, MIT.

A security review agent that examines application code for common vulnerabilities, exposed secrets, unsafe input handling, and insecure dependencies. OWASP is a widely used set of web-application security risks.

In plain words
What is it for?
Use it to review web applications and APIs, check for hardcoded credentials, assess dependencies, look for injection and request-forgery risks, and apply secure coding patterns.
Why use it?
It helps find security problems before code reaches production, including issues involving authentication, APIs, dependencies, and user input.

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 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 3d 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 by conducting thorough security reviews of code, configurations, and dependencies.

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

Tools at Your Disposal

Security Analysis Tools

  • npm audit - Check for vulnerable dependencies
  • eslint-plugin-security - Static analysis for security issues

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.
