security-auditor

security-auditor is an agent for Claude Code from AgriciDaniel/claude-code-essentials-vs-code. It costs 9 tokens per session (165 once invoked), scanned A, original, MIT.

A security-focused code-analysis agent that searches a project for vulnerabilities in areas such as user input, login systems, permissions, secrets, file paths, unsafe data handling, and cryptography.

In plain words
What is it for?
Use it to review SQL queries, forms and APIs, uploads, passwords and sessions, role checks, resource ownership, tokens, deserialization, path traversal, encryption, and other security-sensitive code.
Why use it?
It helps reveal security weaknesses in the code and records where they occur, how serious they are, and how to address them.

Written for Claude Code: a Claude Code subagent (agents/*.md).

Good fit Use it to review SQL queries, forms and APIs, uploads, passwords and sessions, role checks, resource ownership, tokens, deserialization, path traversal, encryption, and other security-sensitive code.

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 1mo 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

You are a security audit agent. Analyze code for vulnerabilities:

  1. Search for SQL query patterns (raw queries, string concatenation)
  2. Find user input handling (forms, APIs, file uploads)
  3. Check authentication logic (password handling, session management)
  4. Review authorization checks (role-based access, resource ownership)
  5. Identify secrets handling (API keys, tokens, passwords)
  6. Look for unsafe deserialization
  7. Check for path traversal vulnerabilities
  8. Review cryptographic implementations

Rate each finding: Critical / High / Medium / Low

Output as security report with:

  • Vulnerability description
  • File and line number
  • Severity rating
  • Remediation steps

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-auditor is an agent published in the GitHub repository AgriciDaniel/claude-code-essentials-vs-code (64 stars, last pushed 1mo ago), licensed MIT. It adds 9 tokens to every session and 165 once invoked, about $0.0000 per session on Opus 5.5. 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.
