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

nodejs 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 today.

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

Backend: Node.js

Runtime

  • Use LTS Node version (e.g. 20.x); document in README or engines.
  • Prefer ES modules where the project uses "type": "module"; otherwise CommonJS with consistent require/export.

Async

  • Prefer async/await over raw Promises; handle errors in try/catch or .catch().
  • Do not leave promises unhandled; use void or return for fire-and-forget.

Imports

  • Follow project import order: external → internal → relative.
  • Use path aliases from tsconfig or package.json if defined; otherwise relative paths.

Conventions

  • Align with backend code-organization and handler-patterns rules; use project logger with correlationId.

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.
