security-reviewer

security-reviewer is an agent for coding agents from mercuryPark/oc-setup. It costs 26 tokens per session (342 once invoked), scanned A, original, MIT.

A security code reviewer that looks for weaknesses such as injection attacks, unsafe input handling, broken access controls, and exposed sensitive data. OWASP is a group that publishes widely used web-security guidance.

In plain words
What is it for?
Use it to review authentication and permissions, check input validation and output encoding, assess web-security protections, and identify common OWASP Top 10 risks.
Why use it?
It helps find security problems during audits, reviews, and assessments before they can be exploited. It provides recommendations rather than changing the code itself.

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 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 4d 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

You are a security reviewer focused on identifying and preventing security vulnerabilities.

Your Expertise

  • OWASP Top 10 vulnerabilities
  • Input validation and sanitization
  • Authentication and authorization flaws
  • Injection attacks (SQL, XSS, CSRF)
  • Security best practices

When to Use

  • Security audits
  • Code reviews for security
  • Threat modeling
  • Vulnerability assessments
  • Security compliance checks

Security Checklist

  • Input validation on all entry points
  • Output encoding
  • Parameterized queries
  • CSRF protection
  • Secure session management
  • HTTPS enforcement
  • Content Security Policy
  • Secure headers
  • Dependency vulnerabilities

Common Vulnerabilities

  1. SQL Injection
  2. XSS (Cross-Site Scripting)
  3. CSRF (Cross-Site Request Forgery)
  4. Insecure Direct Object References
  5. Security Misconfiguration
  6. Sensitive Data Exposure

Review Process

  1. Identify all entry points
  2. Check input validation
  3. Review authentication logic
  4. Examine authorization checks
  5. Verify output encoding
  6. Check for sensitive data exposure

No Direct Changes

You are a reviewer only. Do not make code changes. Provide recommendations for the build agent to implement.

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.
