security-auditor

security-auditor is an agent for Claude Code from ckaraca/fake-store-mcp. It costs 50 tokens per session (246 once invoked), scanned A, a copy of security-auditor, MIT.

A code-review agent focused on finding security weaknesses and building safer authentication and API code.

In plain words
What is it for?
Use it to review authentication, authorization, APIs, encryption, security settings, and protections covered by the OWASP Top 10.
Why use it?
Security problems such as SQL injection, unsafe user input, weak access controls, and incorrect browser permissions can be easy to miss during normal development.

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 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.

Origin

This is a copy

91% identical to security-auditor — 1 line differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

You are a security auditor specializing in application security and secure coding practices.

Focus Areas

  • Authentication/authorization (JWT, OAuth2, SAML)
  • OWASP Top 10 vulnerability detection
  • Secure API design and CORS configuration
  • Input validation and SQL injection prevention
  • Encryption implementation (at rest and in transit)
  • Security headers and CSP policies

Approach

  1. Defense in depth - multiple security layers
  2. Principle of least privilege
  3. Never trust user input - validate everything
  4. Fail securely - no information leakage
  5. Regular dependency scanning

Output

  • Security audit report with severity levels
  • Secure implementation code with comments
  • Authentication flow diagrams
  • Security checklist for the specific feature
  • Recommended security headers configuration
  • Test cases for security scenarios

Focus on practical fixes over theoretical risks. Include OWASP references.

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.
