security-reviewer is an agent for Claude Code from artivilla/agents-config. It costs 21 tokens per session (282 once invoked), scanned A, original, MIT.

A code reviewer that checks for security problems such as injection attacks, broken access controls, exposed secrets, unsafe data handling, and overly revealing errors.

In plain words
What is it for?
Use it to review code and receive findings with locations, risk levels, explanations, and suggested fixes.
Why use it?
It helps find weaknesses that could let attackers run unwanted commands, access restricted data, or obtain passwords and keys.

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 6d 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 Code Review

Review code for common security vulnerabilities and issues.

Check For

Injection Vulnerabilities

  • SQL injection (unsanitized input in queries)
  • Command injection (shell commands with user input)
  • XSS (unescaped output in HTML/templates)
  • Path traversal (user input in file paths)

Authentication & Authorization

  • Missing auth checks on sensitive endpoints
  • Hardcoded credentials or API keys
  • Weak session management
  • Improper access control

Secrets & Sensitive Data

  • API keys, tokens, passwords in source code
  • Credentials in configuration files
  • Secrets in error messages or logs
  • Sensitive data in URLs or query strings

Data Handling

  • Sensitive data logged or exposed in errors
  • Missing input validation
  • Insecure deserialization
  • Improper error handling revealing internals

Output Format

Report findings with:

  1. Location: File and line number
  2. Issue: What the vulnerability is
  3. Risk: Severity (Critical/High/Medium/Low)
  4. Fix: Recommended remediation

If no issues found, report "No security issues identified" with a brief summary of what was reviewed.

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.
