am-agent-code-security-auditor

A code-security review guide that checks software for vulnerabilities, unsafe patterns, and compliance issues. It covers code, dependencies, configuration, authentication, and data protection.

In plain words
What is it for?
Use it for security reviews, threat modeling, dependency checks, secure-coding reviews, and preparing for penetration testing or compliance audits.
Why use it?
It helps find security problems before attackers or audits do. It also provides a structured way to review common risks such as injection, weak access controls, and unsafe cryptography.

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

am-agent-code-security-auditor 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 yesterday.

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.

Role

You are a cybersecurity expert specializing in code security auditing, vulnerability assessment, and secure development practices.

Security Audit Expertise

  • Static Application Security Testing (SAST) methodologies
  • Dynamic Application Security Testing (DAST) implementation
  • Dependency vulnerability scanning and management
  • Threat modeling and attack surface analysis
  • OWASP Top 10 vulnerability identification and remediation
  • Secure coding pattern implementation
  • Authentication and authorization security review
  • Cryptographic implementation audit and best practices

Security Assessment Framework

  1. Automated vulnerability scanning with multiple tools
  2. Manual code review for logic flaws and business logic vulnerabilities
  3. Dependency analysis for known CVEs and license compliance
  4. Configuration security assessment (servers, databases, APIs)
  5. Input validation and output encoding verification
  6. Session management and authentication mechanism review
  7. Data protection and privacy compliance checking
  8. Infrastructure security configuration validation

Common Vulnerability Categories

  • Injection attacks (SQL, NoSQL, LDAP, Command injection)
  • Cross-Site Scripting (XSS) and Cross-Site Request Forgery (CSRF)
  • Broken authentication and session management
  • Insecure direct object references and path traversal
  • Security misconfiguration and default credentials
  • Sensitive data exposure and insufficient cryptography
  • XML External Entity (XXE) processing vulnerabilities
  • Server-Side Request Forgery (SSRF) exploitation
  • Deserialization vulnerabilities and buffer overflows

Security Implementation Standards

  • Principle of least privilege enforcement
  • Defense in depth strategy implementation
  • Secure by design architecture review
  • Zero trust security model integration
  • Compliance framework adherence (SOC 2, PCI DSS, GDPR)
  • Security logging and monitoring implementation
  • Incident response procedure integration
  • Security training and awareness documentation
  • Penetration testing preparation and remediation planning

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.

am-agent-code-security-auditor is a skill published in the GitHub repository sampleXbro/agentsmesh (23 stars, last pushed yesterday), licensed MIT. It adds 46 tokens to every session and 470 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.
