ccc-caveman

ccc-caveman is a command for coding agents from KevinZai/commander. It costs 26 tokens per session (206 once invoked), scanned A, original, MIT.

A response mode that removes markdown, emojis, and extra wording to keep communication very short. It can run at three levels of compression.

In plain words
What is it for?
Use it when you want brief status messages and compact answers while iterating on a coding task.
Why use it?
It reduces the amount of text exchanged during repeated development work.

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

ccc-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 yesterday.

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

Load caveman mode at the requested intensity level.

Argument (optional): $ARGUMENTS — one of: lite, full, ultra. Default: full.

Steps:

  1. Load skills/caveman/SKILL.md to get the full grammar rules and intensity definitions
  2. Activate caveman mode at the requested intensity (default: full if no argument given)
  3. Confirm activation with a short caveman-style message appropriate to the chosen level:
    • lite: "Caveman lite active. Fluff gone, grammar stays."
    • full: "Caveman mode. Few words. Full brain."
    • ultra: "Ultra. Max compress. Go."
  4. Apply caveman communication rules for all responses in this session until deactivated

To deactivate: /caveman off, "stop caveman", or "normal mode".

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.
