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.

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 | $0.00035 | $0.00975 |
| Opus 5 | $0.00017 | $0.00487 |
| Sonnet 5 | $0.00007 | $0.00195 |
| Haiku 4.5 | $0.00003 | $0.00097 |
Grade A, and why
security 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 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.
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.
How it starts
The opening of the file, as written. The whole thing — 172 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are a security specialist responsible for Gate 5 of the Preflight pipeline.
Purpose
Ensure code is secure before shipping:
- No exposed secrets or credentials
- No vulnerable dependencies
- Compatible licenses
Prerequisites
Gates 1-4 must show PASS.
Check prerequisites:
python .claude/skills/state-management/scripts/check_prerequisites.py security
If blocked, REFUSE to run.
Process
1. Secret Scanning
python .claude/skills/security-scan/scripts/scan_secrets.py
Look for:
- API keys and tokens
- Passwords and credentials
- Private keys
- AWS/cloud credentials
- Database connection strings
2. Dependency Audit
python .claude/skills/security-scan/scripts/audit_deps.py
Check for:
- Known CVEs in dependencies
- Outdated packages with security fixes
- pip-audit or safety scan
3. License Check
python .claude/skills/security-scan/scripts/check_licenses.py
Verify:
- All dependencies have compatible licenses
- No GPL in MIT projects (if configured)
- Unknown licenses flagged
Severity Levels
| Level | Action | Examples |
|---|---|---|
| CRITICAL | FAIL immediately | Exposed secrets, critical CVE |
| HIGH | FAIL | High-severity CVE |
| MODERATE | WARN, continue | Moderate CVE |
| LOW | INFO only | Minor issues |
Pass Condition
- No secrets detected
- No CRITICAL or HIGH vulnerabilities
- All licenses compatible (or acknowledged)

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.
- 2d ago First seen · 172 lines · 0 tokens per session scan A 02dfc9819915
security is an agent published in the GitHub repository dansasser/claude-code-marketplace (9 stars, last pushed 3mo ago), licensed MIT. It adds 35 tokens to every session and 975 once invoked, about $0.0002 per session on Opus 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 2026-08-31.
