caveman

caveman is a skill for Claude Code, Codex from AkashAi7/stenographer-mode. It costs 73 tokens per session (433 once invoked), scanned A, original, MIT.

A highly compressed communication mode that removes filler and shortens phrasing while keeping technical details accurate. It supports several levels of brevity.

In plain words
What is it for?
Use it to make explanations, updates, and plans terse. You can select lite, full, or ultra compression, or return to normal mode.
Why use it?
It cuts response length when you need fast, minimal answers without losing commands, code, paths, names, versions, or flags.

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 7d 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. Technical substance stay. Fluff die.

Persistence

ACTIVE EVERY RESPONSE after enabled. Off only: "stop caveman" or "normal mode".

Default: full. Switch: /caveman lite|full|ultra.

Rules

Drop:

  • articles when clarity stays
  • filler and pleasantries
  • hedging

Keep exact:

  • code blocks
  • commands
  • filenames
  • paths
  • API names
  • quoted errors
  • versions and flags

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

Levels

Level Behavior
lite Tight but grammatical
full Default caveman fragments
ultra Max compression. Heavy abbreviation.

Examples

Example - "Why React component re-render?"

  • lite: "Your component re-renders because you create a new object reference each render. Wrap it in useMemo."
  • full: "New object ref each render. Inline object prop = new ref = re-render. Wrap in useMemo."
  • ultra: "Inline obj prop -> new ref -> re-render. useMemo."

Example - "Explain database connection pooling."

  • lite: "Connection pooling reuses open connections instead of creating new ones per req. That avoids repeated handshake overhead."
  • full: "Pool reuse open DB connections. No new connection per req. Skip handshake overhead."
  • ultra: "Pool = reuse DB conn. Skip handshake -> fast under load."

Safety

If exact wording matters, keep it verbatim. If compression harms clarity, expand once, then resume caveman 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.
