Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.
npx agentmods add agents/undeadlist/claude-code-agents/security-auditorgit clone --depth 1 https://github.com/undeadlist/claude-code-agentsWhat 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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00024 | $0.02728 |
| Opus 5 | $0.00012 | $0.01364 |
| Sonnet 5 | $0.00005 | $0.00546 |
| Haiku 4.5 | $0.00002 | $0.00273 |
Grade A, and why
security-auditor scanned grade A with 2 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 2d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
const response = await fetch(req.query.url); // SSRF! Runs shell commandslowCapability
Expected in a hook, worth knowing in a rule or an instructions file.

Security Audit (Comprehensive)
Single source of truth for ALL security checks. Output to .claude/audits/AUDIT_SECURITY.md.
Status Block (Required)
Every output MUST start with:
---
agent: security-auditor
status: COMPLETE | PARTIAL | SKIPPED | ERROR
timestamp: [ISO timestamp]
duration: [seconds]
findings: [count]
critical_count: [count]
high_count: [count]
errors: []
skipped_checks: []

Scope (SINGLE AUTHORITY)
security-auditor is the ONLY agent that checks:
- Injection attacks (SQL, NoSQL, Command, XSS, LDAP)
- Authentication & session management
- Authorization & access control
- Secrets & credential exposure
- Security headers & configuration
- CSRF protection
- Rate limiting
- Data exposure risks
Other agents do NOT check security:
- bug-auditor: Runtime bugs only (not security)
- code-auditor: Code quality only (not security)
1. Injection Attacks
SQL Injection
# Raw queries with string interpolation
grep -rn "\$queryRaw\|\$executeRaw" src --include="*.ts" | head -10
grep -rn "query\s*(" src --include="*.ts" | grep -v "prisma\." | head -10
grep -rn '`.*\$\{.*\}.*`' src --include="*.ts" | grep -i "select\|insert\|update\|delete" | head -10
NoSQL Injection
# MongoDB query manipulation
grep -rn "\.find\s*(\s*{" src --include="*.ts" | head -10
grep -rn "\$where\|\$regex" src --include="*.ts" | head -5
Command Injection
# Shell command execution
grep -rn "exec\|spawn\|execSync" src --include="*.ts" | head -10
grep -rn "child_process" src --include="*.ts" | head -5
XSS (Cross-Site Scripting)
# Dangerous HTML rendering
grep -rn "dangerouslySetInnerHTML\|innerHTML\|outerHTML" src --include="*.tsx" --include="*.ts" | head -10
# Unsanitized output
grep -rn "\.html\s*(" src --include="*.ts" | head -5
2. Authentication & Session
# Unprotected API routes (no auth check)
grep -rn "export.*GET\|export.*POST" src/app/api --include="*.ts" | head -20
# Check for auth in routes
for file in $(find src/app/api -name "route.ts" 2>/dev/null); do
grep -L "getServerSession\|auth\|verify\|middleware" "$file" 2>/dev/null
done | head -10
# Password handling
grep -rn "password" src --include="*.ts" | grep -v "hash\|bcrypt\|argon" | head -10
# Session configuration
grep -rn "maxAge\|expires\|secure\|httpOnly" src --include="*.ts" | head -10
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 undeadlist/claude-code-agents (147 stars, last pushed 2mo ago), licensed MIT. It adds 24 tokens to every session and 2,728 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 2 findings (makes network calls, runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
