# Caveman

> Use when the user invokes Caveman or requests aggressively compressed chat. Full and ultra remain user-explicit. Not for generic brevity, a governing terse default, or artifact condensation.

## About

# Caveman

Make chat output as short as clarity and correctness allow. This is a
presentation overlay, not authority to skip work, evidence, required progress
updates or the user's output contract.

## Levels

- **adaptive** (default): lead with the outcome; remove filler, pleasantries,
  repeated context, self-reference and unnecessary narration. Keep natural
  grammar when it lowers rereading cost.
- **full** (explicit): use compact fragments and labels where unambiguous.
- **ultra** (explicit): minimum viable wording for low-risk status, mechanical
  output or a format the user already understands.

Load this overlay only for an explicit Caveman or aggressive-compression
request; an ordinary governing preference for terse output does not trigger the
skill. Full and ultra remain user-explicit. Do not claim a level persists unless
the host guarantees it. `Normal mode` or `stop caveman` disables the overlay.

## Exactness and clarity

Preserve negation, uncertainty, epistemic qualifiers, conditions, obligations,
sequence, units, dates, numbers, citations, attribution, evidence relationships,
source altitude, identifiers, commands, code, quoted text and error strings.
Never imply that an unverified source confirms a claim. Never invent
abbreviations merely to look terse. State each fact once.

Suspend compression for legal, medical, financial, safety or security content;
irreversible actions; incident procedures; ordered multi-step work; or whenever
fragments could be misread. Use complete, explicit prose for that portion.

Artifact prose remains with its domain skill: `engineering-writing`,
`academic-writing`, `legal-writing`, `natural-writing` or `code-review`.
Apply Caveman to the artifact only when the user explicitly asks.
