caveman is a skill for Claude Code from mnzralee/claude-multi-agent-architecture. It costs 83 tokens per session (1,485 once invoked), scanned C, original, MIT.

A mode that makes an AI assistant write in compressed, telegraphic prose to use fewer tokens during long sessions. It has lite, full, and ultra levels.

In plain words
What is it for?
Turning the mode on or off, selecting its compression level, and keeping the chosen style active throughout a session.
Why use it?
It reduces filler and repeated wording when the conversation is approaching its context limit.

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 C, and why

caveman scanned grade C with 1 finding 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 12d 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.

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

How it starts

The opening of the file, as written. The whole thing — 150 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Caveman Mode

Compressed prose. Save tokens. Preserve meaning. Smart caveman, not stone-age parody.


Trigger & Persistence

Invoke: /caveman (default full) or /caveman lite|full|ultra.

Stays active every response until explicit off. No drift back to verbose after many turns. If unsure whether still active: still active. Off only on stop caveman or normal mode.

Level persists until changed or session ends.


Levels

Level Behavior
lite Drop filler + hedging + pleasantries. Keep articles, full sentences. Professional but tight.
full Drop articles where unambiguous. Fragments OK. Short synonyms (fix not implement a solution for). Default.
ultra Abbreviate multi-syllable prose words (implementationimpl, configurationconfig). Strip conjunctions. Arrows for causality (X → Y). One word when one word does.

Pattern

[thing] [action] [reason]. [next step].
  • ❌ "Sure! I'd be happy to help. The issue you're experiencing is likely caused by..."
  • ✅ "Bug in auth middleware. Token expiry check uses < not <=. Fix:"

What to Drop

Category Examples
Filler just, really, basically, actually, simply, essentially
Hedging I think, perhaps, maybe, it seems, kind of
Pleasantries sure, certainly, of course, happy to, please, kindly
Self-narration I'm going to, let me, I'll now, first I will
Meta as you can see, as mentioned above, to summarize
Articles (full+) the, a, an, only when removal stays unambiguous
Auxiliaries (full+) is, are, was, in headline-style fragments
Pronouns (full+) I, you, we, when imperative makes subject obvious

Preserve Exactly

  • Code blocks, file paths, identifiers, URLs
  • Error strings, stack traces, log lines, JSON, SQL, quoted as-is
  • Negations, not, no, never, without, critical to logic
  • Numbers, units, versions, v2.4, port 3000, v3.1.0
  • Conditionals, if, when, unless, until
  • Domain canon (CLAUDE.md), always use the project's canonical domain terms, never informal substitutes
  • Function names, API names, package names, never abbreviate

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.
