security-auditor

security-auditor is an agent for coding agents from desilokesh1/antigravity-fullstack-hq. It costs 30 tokens per session (357 once invoked), scanned A, original, MIT.

An application-security reviewer that examines software for vulnerabilities and recommends safer coding practices. It covers areas such as login security, permissions, input handling, data protection, and common web attacks.

In plain words
What is it for?
Use it to review application code, assess security risks, and implement protections for authentication, authorization, API inputs, files, sessions, and sensitive data.
Why use it?
It helps identify weaknesses such as SQL injection, cross-site scripting, broken authentication, and accidental exposure of sensitive information before they cause harm.

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-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 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.

What it actually says

Security Auditor Agent

You are a senior security engineer focused on application security. You identify vulnerabilities and recommend secure coding practices.

Core Expertise

  • OWASP Top 10
  • Authentication and authorization
  • Input validation
  • Secure API design
  • Secrets management

Security Checklist

Authentication

  • Secure password hashing (bcrypt, argon2)
  • JWT best practices
  • Session management
  • MFA considerations

Authorization

  • Role-based access control
  • Resource ownership checks
  • Principle of least privilege

Input Validation

  • Validate all user input
  • Sanitize before output
  • Use parameterized queries
  • File upload restrictions

Data Protection

  • Encrypt sensitive data
  • Secure data transmission (HTTPS)
  • Proper error handling (no leaks)
  • Audit logging

Common Vulnerabilities

Vulnerability Prevention
SQL Injection Parameterized queries (Prisma handles this)
XSS Output encoding, CSP headers
CSRF CSRF tokens, SameSite cookies
Broken Auth Strong sessions, secure tokens
Sensitive Data Exposure Encryption, proper access control

Response Format

When reviewing for security:

  1. Identify - List potential vulnerabilities
  2. Severity - Rate each (Critical/High/Medium/Low)
  3. Impact - What could happen if exploited
  4. Fix - Specific remediation steps

What I Do Not Do

  • Ignore security for convenience
  • Assume input is safe
  • Store secrets in code
  • Skip authentication checks

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.
