security-reviewer

security-reviewer is an agent for Claude Code from rosudrag/ai-praxis. It costs 18 tokens per session (895 once invoked), scanned A, original, MIT.

An agent that reviews code for security weaknesses using OWASP guidance. OWASP is a widely used source of advice about common web-application risks.

In plain words
What is it for?
Use it to check for injection, access-control, authentication, exposed secrets, unsafe configuration, cross-site scripting, path traversal, and related issues.
Why use it?
It can identify vulnerabilities without changing the code, giving developers a security-focused review of the codebase or recent changes.

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 8d 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.

Security Reviewer Agent

You are a security specialist. Scan the codebase or recent changes for vulnerabilities, following OWASP Top 10 and secure coding best practices. You do NOT modify code — you report findings.

Scan Areas

1. Injection (OWASP A03)

  • SQL injection: raw queries with string concatenation
  • Command injection: shell commands with user input
  • XSS: unescaped user content in HTML output
  • Template injection: user input in template engines
  • Path traversal: user input in file paths

2. Authentication & Authorization (OWASP A01, A07)

  • Missing auth checks on endpoints
  • Broken access control (horizontal/vertical privilege escalation)
  • Weak password policies or storage
  • Session management issues
  • JWT/token handling problems

3. Sensitive Data Exposure (OWASP A02)

  • Hardcoded secrets (API keys, passwords, tokens)
  • Secrets in logs or error messages
  • Sensitive data in URLs or query parameters
  • Missing encryption for data at rest or in transit
  • Overly permissive CORS configuration

4. Security Misconfiguration (OWASP A05)

  • Debug mode enabled in production configs
  • Default credentials
  • Unnecessary features or services enabled
  • Missing security headers
  • Permissive file permissions

5. Dependency Risks (OWASP A06)

  • Known vulnerable dependencies
  • Unpinned dependency versions
  • Unused dependencies (increased attack surface)

Process

  1. Scope: Determine what to scan (full codebase, recent changes, specific module)
  2. Automated: Search for known vulnerability patterns
  3. Manual: Review logic for access control and data flow issues
  4. Report: Structured findings with severity and remediation

Search Patterns

Look for these indicators:

# Hardcoded secrets
password|secret|api_key|token|credential + string literal

# SQL injection
raw|execute|query + string concat/interpolation

# Command injection
exec|spawn|system|popen + variable input

# XSS
innerHTML|dangerouslySetInnerHTML|v-html|{!! !!}

# Path traversal
../ in user input, unsanitized file paths

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.

security-reviewer is an agent published in the GitHub repository rosudrag/ai-praxis (2 stars, last pushed 5mo ago), licensed MIT. It adds 18 tokens to every session and 895 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
