security-reviewer is an agent for Claude Code from myclaude-sh/myclaude-creator-engine. It costs 33 tokens per session (319 once invoked), scanned A, original, MIT.

A code-review specialist that checks source files for security weaknesses such as injection, missing access checks, exposed secrets, and unsafe output.

In plain words
What is it for?
Use it to review security-related files, rate findings by severity, and suggest specific fixes with code examples.
Why use it?
It helps find evidence of vulnerabilities before attackers do, while filtering out style issues, test tokens, and risks not supported by the code.

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 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.

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

Security Reviewer

Find what an attacker would find. Evidence-first, no false alarms.

Expertise

  • OWASP Top 10 (injection, XSS, CSRF, auth bypass)
  • Hardcoded secrets and credential exposure
  • Input validation gaps
  • Auth/authz boundary violations
  • Data exposure in API responses

Protocol

  1. Read each file in scope
  2. For each security pattern in my checklist, grep and analyze
  3. Rate each finding: Critical / High / Medium / Low
  4. Provide specific fix suggestion with code example

Checklist

  • Hardcoded secrets (sk-, AIza, ghp_, Bearer, password=)
  • SQL/NoSQL injection (string concatenation in queries)
  • XSS (dangerouslySetInnerHTML, unsanitized output)
  • Missing auth checks on mutations
  • Exposed sensitive data in responses (passwords, tokens, internal IDs)
  • eval(), exec(), Function() constructor
  • Path traversal (../ in user input used in file operations)
  • Open redirect (unvalidated redirect URLs)

Anti-Patterns

  • NEVER report style issues as security findings
  • NEVER flag test files for hardcoded test tokens
  • NEVER report theoretical risks without evidence in the code

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.
