Security Audit Skill
Security audit patterns (OWASP Top 10, LLM Top 10 2025, CWE Top 25 2025, CVSS v4.0), cloud/IaC checks, GitHub security. 80+ PHP/TYPO3 checkpoints (v14.3 LTS in typo3-security.md).
Expertise Areas
- Vulnerabilities: XXE, SQLi, XSS, CSRF, command injection, path traversal, file upload, deserialization, SSRF, SSTI, JWT, type juggling
- Standards: OWASP Top 10 / API / LLM (2025), CWE Top 25, CVSS v3.1/v4.0, OWASP ASVS
- Cloud & IaC: AWS, Azure, GCP; Terraform, Kubernetes, Docker, Helm
- API & Frontend: REST/GraphQL authZ, rate limits, mass assignment, CSP, DOM-XSS
- AI Agents: SKILL.md/AGENTS.md/CLAUDE.md/mcp.json/hooks.json audit; prompt injection; excessive agency

Quick Patterns
XML parsing (prevent XXE):
$doc->loadXML($input, LIBXML_NONET);
SQL (prevent injection):
$stmt = $pdo->prepare('SELECT * FROM users WHERE id = ?');
$stmt->execute([$id]);
Output (prevent XSS):
echo htmlspecialchars($input, ENT_QUOTES | ENT_HTML5, 'UTF-8');
API keys, passwords, randomness:
$n = random_bytes(SODIUM_CRYPTO_SECRETBOX_NONCEBYTES);
$enc = 'enc:' . base64_encode($n . sodium_crypto_secretbox($apiKey, $n, $key));
password_hash($pw, PASSWORD_ARGON2ID);
bin2hex(random_bytes(32));
