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 5.1 | $0.00081 | $0.00751 |
| Opus 5 | $0.00041 | $0.00376 |
| Sonnet 5 | $0.00016 | $0.00150 |
| Haiku 4.5 | $0.00008 | $0.00075 |
Grade A, and why
security-audit 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 8d 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.
This is a copy
100% identical to security-audit — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Security Audit Skill
Purpose
Comprehensive security scanning and vulnerability detection. Includes input validation, path traversal prevention, CVE detection, and secure coding pattern enforcement.
When to Trigger
- authentication implementation
- authorization logic
- payment processing
- user data handling
- API endpoint creation
- file upload handling
- database queries
- external API integration
When to Skip
- read-only operations on public data
- internal development tooling
- static documentation
- styling changes
Commands
Full Security Scan
Run comprehensive security analysis on the codebase
npx @claude-flow/cli security scan --depth full
Example:
npx @claude-flow/cli security scan --depth full --output security-report.json
Input Validation Check
Check for input validation issues
npx @claude-flow/cli security scan --check input-validation
Example:

Path Traversal Check
Check for path traversal vulnerabilities
npx @claude-flow/cli security scan --check path-traversal
SQL Injection Check
Check for SQL injection vulnerabilities
npx @claude-flow/cli security scan --check sql-injection
XSS Check
Check for cross-site scripting vulnerabilities
npx @claude-flow/cli security scan --check xss
CVE Scan
Scan dependencies for known CVEs
npx @claude-flow/cli security cve --scan
Example:
npx @claude-flow/cli security cve --scan --severity high
Security Audit Report
Generate full security audit report
npx @claude-flow/cli security audit --report
Example:
npx @claude-flow/cli security audit --report --format markdown --output SECURITY.md
Threat Modeling
Run threat modeling analysis
npx @claude-flow/cli security threats --analyze
Validate Secrets
Check for hardcoded secrets
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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 a skill published in the GitHub repository oceanjustinlin/qimen (22 stars, last pushed 1mo ago), licensed MIT. It adds 81 tokens to every session and 751 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to security-audit, differing in 0 lines, and is treated as a copy.
