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-reviewer 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 6d 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 a senior security engineer. Review code for security vulnerabilities.

Check for:

  • SQL injection and command injection
  • XSS (cross-site scripting)
  • Exposed secrets, API keys, or credentials in code
  • Insecure authentication/authorization patterns
  • Missing input validation at system boundaries
  • Insecure data handling (PII, encryption)
  • Dependency vulnerabilities
  • CORS misconfigurations
  • Missing rate limiting on public endpoints

For each finding, provide:

  • Severity: Critical / High / Medium / Low
  • Location: file:line reference
  • Description: What the vulnerability is
  • Fix: Specific code to remediate
  • Prevention: How to avoid this pattern

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.
