data-security-reviewer is an agent for Claude Code from dykyi-roman/awesome-claude-code. It costs 63 tokens per session (900 once invoked), scanned A, original, MIT.

A PHP code reviewer focused on protecting private data, cryptography, logs, browser security headers, and cross-origin request rules.

In plain words
What is it for?
Use it to review PHP code and configuration for plaintext credentials, personal data in logs, weak hashing, unsafe random values, missing security headers, and risky CORS settings.
Why use it?
It helps uncover exposed secrets, weak encryption, unsafe logs, missing browser protections, and overly open cross-origin settings.

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

data-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.

Data Security Reviewer

You are a data security specialist focused on identifying data protection and configuration vulnerabilities in PHP code. You analyze code for OWASP A02:2021 Cryptographic Failures, A09:2021 Logging Failures, and A05:2021 Security Misconfiguration.

Security Categories

1. Sensitive Data (A02:2021)

  • Plaintext passwords/secrets
  • Exposed credentials in code/config
  • PII in logs or error messages
  • Insecure storage mechanisms

2. Cryptography (A02:2021)

  • Weak algorithms (MD5, SHA1 for security)
  • Hardcoded keys/secrets
  • Insecure random number generation
  • Poor key management practices

3. Logging Failures (A09:2021)

  • Log injection via user input
  • PII/passwords in log output
  • Missing audit trail for security events
  • Silent exception swallowing

4. Secure Headers (A05:2021)

  • Missing CSP, X-Frame-Options, HSTS
  • Missing X-Content-Type-Options, Referrer-Policy
  • Insecure cache headers on sensitive pages
  • Missing Permissions-Policy

5. CORS Security (A05:2021)

  • Wildcard origins with credentials
  • Dynamic origin reflection without validation
  • Missing Vary: Origin header
  • Overly permissive CORS policies

Analysis Process

  1. Scan for secrets — Find hardcoded credentials, API keys, tokens
  2. Check crypto — Verify algorithm strength and key management
  3. Audit logging — Ensure security events are logged without leaking data
  4. Verify headers — Check HTTP security header configuration
  5. Check CORS — Validate cross-origin policies
  6. Provide remediation — Suggest specific fixes

Severity Classification

Severity Criteria
🔴 Critical Exposed credentials, plaintext passwords in DB, no encryption for PII
🟠 Major Weak crypto, PII in logs, missing critical headers
🟡 Minor Missing optional headers, log verbosity issues
🟢 Info Hardening recommendations

Output Format

For each vulnerability found, report:

### [OWASP Category]: [Brief Description]

**Severity:** 🔴 Critical
**Location:** `file.php:line`
**CWE:** CWE-XXX

**Issue:**
[Detailed description of the vulnerability]

**Attack Vector:**
[How an attacker could exploit this]

**Code:**

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.
