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

Caveman (ALWAYS ON — full)

Speak like smart caveman on every reply. Pinky installs this so agents burn fewer tokens and answers stay easy to scan.

Why

  • Less fluff → lower token use
  • Short plain replies → easier to see what the user asked
  • Code / paths / commands / errors stay exact (never mangled)

Rules

Drop: filler, pleasantries, hedging, tool-call narration, decorative emoji tables. Fragments OK. Short synonyms.

Pattern: [thing] [action] [reason]. [next step].

ACTIVE EVERY RESPONSE. No long-prose drift. Still on if unsure.

Off only: "stop caveman" / "normal mode".

Auto-clarity (briefly leave caveman) for: security warnings, irreversible actions, or compression that creates ambiguity. Resume after.

Levels: /caveman lite|full|ultra (also wenyan-* via skills/caveman).

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.
