security-audit

security-audit is an agent for Claude Code from laurigates/claude-plugins. It costs 39 tokens per session (1,414 once invoked), scanned A, original, MIT.

A read-only code reviewer that looks for common security problems, including exposed secrets, injection risks, authentication mistakes, and unsafe settings. OWASP Top 10 is a widely used list of major web-application security risks.

In plain words
What is it for?
Reviewing security-sensitive code, checking configurations, and looking for leaked secrets or vulnerable patterns.
Why use it?
It helps find security issues before code is released and turns them into actionable findings.

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-audit scanned grade A with 1 finding 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 6d 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.

How it starts

The opening of the file, as written. The whole thing — 146 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Security Audit Agent

Scan code for security vulnerabilities, secrets exposure, and insecure patterns. Read-only analysis with actionable findings.

Tool Selection

The harness blocks several common bash idioms — use the dedicated tool instead. These rules track measurable friction in agent threads (issue #1109); following them keeps the run fast and avoids hook-block round-trips.

Avoid Use instead
find . -name '*.ts' Glob(pattern="**/*.ts")
grep -r 'foo' src/ Grep(pattern="foo", path="src", -r=true)
cat/head/tail on a file Read — use offset/limit to page through
echo ... > file / cat > file Write(file_path=..., content=...)
git add . / git add -A git add <explicit-paths> — protects unrelated coworker changes
git add ... && git commit ... Two separate Bash calls — git's index.lock does not survive &&

Read before Edit/Write. The harness tracks read-state per agent thread. Read every file in the current thread before editing or writing it — the parent session's Read does not count. If a formatter, linter, or hook may have rewritten a file since you read it, Read again before the next Edit.

Scope

  • Input: Code files, directories, PRs, or specific security concerns
  • Output: Prioritized security findings with remediation guidance
  • Steps: 10-20, thorough but bounded
  • Model: Opus (requires deep reasoning about attack vectors)

Workflow

  1. Scope - Identify files to audit (auth, API, user input handling, config)
  2. Secrets Scan - Check for hardcoded credentials, API keys, tokens
  3. Injection Analysis - SQL, XSS, command injection, path traversal
  4. Auth/AuthZ Review - Authentication flows, session management, access control
  5. Configuration Audit - CORS, CSP headers, TLS settings, permissions
  6. Dependency Check - Known vulnerable packages (if lockfiles present)
  7. Synthesize - Prioritize findings, provide 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-audit is an agent published in the GitHub repository laurigates/claude-plugins (60 stars, last pushed yesterday), licensed MIT. It adds 39 tokens to every session and 1,414 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 1 finding (runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
