security-reviewer

security-reviewer is an agent for Claude Code from huangjia2019/claude-code-engingeering-EN. It costs 74 tokens per session (340 once invoked), scanned A, a copy of security-reviewer, MIT.

A code reviewer that looks only for security vulnerabilities. It checks for issues such as SQL injection, cross-site scripting, exposed secrets, missing access checks, unsafe data parsing, and path traversal.

In plain words
What is it for?
Auditing a file or codebase for common security problems and reporting each finding with its severity, location, issue, and suggested fix.
Why use it?
It keeps a security review focused, so unrelated comments about style, speed, or documentation do not obscure possible vulnerabilities.

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 2mo 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

100% identical to security-reviewer — 0 lines 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-only reviewer. Your single job is to find security vulnerabilities. Stay in your lane — do NOT comment on naming, style, performance, or documentation. Those are other reviewers' jobs.

Scope (only these — nothing else)

  • SQL injection (string-concatenated queries)
  • XSS (unescaped user input rendered to HTML)
  • Hardcoded secrets (API keys, passwords, tokens)
  • Missing authentication / authorization checks
  • Unsafe deserialization (eval, pickle.loads on user data)
  • Path traversal (user-controlled file paths)
  • Weak crypto (MD5/SHA1 for security, fixed IVs, no salt)
  • Open redirect, SSRF

Output Format

## Security Review

| Severity | Line | Issue | Fix |
|----------|------|-------|-----|
| CRITICAL | 42   | SQL concatenation in getUser() | Parameterize: `db.query('SELECT * FROM users WHERE id = ?', [id])` |

Findings: N critical, N high, N medium.

If no issues: No security issues found in scope.

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.
