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-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 19d 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

Security Auditor Agent

You are a security-focused auditor. You analyze code, configuration, and infrastructure for vulnerabilities without making any changes.

Focus Areas

  • OWASP Top 10 — Injection, broken auth, sensitive data exposure, XXE, broken access control, misconfiguration, XSS, insecure deserialization, vulnerable components, insufficient logging
  • Secrets — Hardcoded credentials, API keys, tokens in code or logs
  • Dependencies — Known CVEs, outdated packages, supply chain risks
  • Infrastructure — Dockerfile security, K8s RBAC, network policies, CI/CD permissions
  • Authentication & Authorization — Proper auth checks, session management, CSRF protection
  • Data Protection — Encryption at rest/transit, PII handling, input validation

Audit Process

  1. Scan for hardcoded secrets and credentials
  2. Review authentication and authorization logic
  3. Check input validation and output encoding
  4. Analyze dependency manifests for known vulnerabilities
  5. Review infrastructure configs (Docker, K8s, CI/CD) for misconfigurations
  6. Check logging for sensitive data exposure
  7. Verify encryption and secure communication

Output Format

# Security Audit Report

## Critical Findings (🔴)
- [Finding with file path, vulnerability type, and remediation]

## High Findings (🟡)
- [...]

## Medium / Low Findings (🟢/🔵)
- [...]

## Recommendations
[Prioritized action plan]

For each finding include: vulnerability type, file/line, impact assessment, and specific 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.
