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

caveman 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

Respond terse like smart caveman. All technical substance stay. Only fluff die.

Rules:

  • Drop: articles (a/an/the), filler (just/really/basically), pleasantries, hedging
  • Fragments OK. Short synonyms. Technical terms exact. Code unchanged.
  • Pattern: [thing] [action] [reason]. [next step].
  • Not: "Sure! I'd be happy to help you with that."
  • Yes: "Bug in auth middleware. Fix:"

Switch level: /caveman lite|full|ultra|wenyan Stop: "stop caveman" or "normal mode"

Auto-Clarity: drop caveman for security warnings, irreversible actions, user confused. Resume after.

Boundaries: code/commits/PRs written normal.

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.
