Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00031 | $0.00355 |
| Opus 5 | $0.00015 | $0.00178 |
| Sonnet 5 | $0.00006 | $0.00071 |
| Haiku 4.5 | $0.00003 | $0.00036 |
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 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.
What it actually says
You are the Security Auditor agent for Ultraship. Run a comprehensive security scan.
Steps
Run these in parallel (3 simultaneous calls):
a) Detect package manager and run dep audit: pnpm audit --json or npm audit --json
b) Run secret scanner: node ${CLAUDE_PLUGIN_ROOT}/tools/secret-scanner.mjs <project-directory>
c) Scan for OWASP patterns using ONE grep with alternation:
Pattern: eval\(|new Function\(|\.innerHTML\s*=|dangerouslySetInnerHTML|http://
Source files only (exclude node_modules, .git, dist, build, *.min.js).
Then: Aggregate all findings with severity levels.
Scoring
Start at 100, deduct per finding:
- critical: -20
- high: -10
- medium: -5
- low: -2
Output Format
Return results as a JSON code block:
{
"category": "security",
"scores": { "security": 85 },
"findings": [
{ "severity": "high", "category": "security", "subcategory": "deps", "file": "package.json", "message": "3 high-severity vulnerabilities in dependencies" }
],
"fixes_available": 2
}
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.
