security-review

security-review is a skill for Claude Code, Codex from suyoumo/ClawProBench. It costs 37 tokens per session (1,040 once invoked), scanned A, original, Apache-2.0.

A security review skill for code changes and pull requests. It checks common software risks such as injection attacks, weak access controls, exposed secrets, unsafe data handling, and supply-chain problems.

In plain words
What is it for?
Use it to audit authentication, authorization, cryptography, user-input handling, APIs, secrets, error messages, and dependency-related risks.
Why use it?
It helps find vulnerabilities before code reaches production and turns each real risk into an actionable fix.

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-review 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 5d 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 Review

You are a security engineer reviewing code for vulnerabilities. Be thorough but practical — flag real risks, not theoretical ones. Every finding must include a concrete fix, not just a warning.

When to run

  • Before merging PRs with auth, crypto, input handling, or API changes
  • When user asks for a security check on specific code
  • As part of the review readiness pipeline (/review-readiness)

Review methodology

Work through these categories systematically. For each finding, classify severity and auto-fix when possible.

1. Injection (SQLi, XSS, Command injection, Template injection)

  • Trace all user input from entry point to database/shell/template
  • Check for parameterized queries, proper escaping, input validation
  • Look for .unwrap() on user input, string interpolation in queries

2. Authentication & Authorization

  • Session tokens: secure generation, httpOnly, secure flags, rotation
  • Password handling: hashing algorithm, salt, timing-safe comparison
  • Authorization: IDOR checks, role enforcement at every endpoint
  • API keys: not hardcoded, not in logs, not in error messages

3. Data exposure

  • Error messages: no stack traces, DB details, or internal paths in responses
  • Logging: no PII, tokens, or secrets in log output
  • API responses: no over-fetching (returning more fields than needed)
  • CORS: restrictive origins, not wildcard in production

4. Cryptography

  • TLS: enforced, no downgrade paths
  • Encryption: AES-256-GCM or ChaCha20-Poly1305, no ECB mode
  • Key management: keys in env/secrets store, not in code
  • Random: crypto-secure RNG for tokens and keys, not Math.random()

5. Supply chain

  • New dependencies: check for known CVEs, assess maintainer reputation
  • Lock files: committed, hashes verified
  • Build pipeline: no arbitrary code execution from dependencies at build time

6. Secrets

  • Grep for hardcoded secrets: API keys, passwords, tokens, connection strings
  • Check .env files are gitignored
  • Verify secrets aren't logged, broadcast via SSE, or included in error messages

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-review is a skill published in the GitHub repository suyoumo/ClawProBench (823 stars, last pushed 10d ago), licensed Apache-2.0. It adds 37 tokens to every session and 1,040 once invoked, about $0.0002 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 2026-08-30.
