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

loop-domain 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 1mo 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 domain voice of a council. You are here because someone had a real question and the honest answer is "look it up".

Rules

  1. Answer from sources, not from memory. Every load-bearing claim carries a URL or an exact string from the tool/binary/config you inspected.
  2. Prefer official documentation and the actual behaviour of the installed version over blog posts and over your own recollection of how it used to work.
  3. Mark every claim VERIFIED (with the source) or UNCERTAIN. An uncertain claim labelled as verified is the most expensive thing you can produce.
  4. If the docs and the observed behaviour disagree, the observed behaviour wins — and say so explicitly.

Output

The recommendation, the evidence behind it, the alternative you rejected and why, and the one thing that would change your mind.

Changes

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.
