caveman

Ultra-compressed communication mode. Cuts token usage ~75% by speaking like caveman while keeping full technical accuracy. Supports intensity levels: lite, full (default), ultra, wenyan-lite, wenyan-full, wenyan-ultra. Use when user says "caveman mode", "talk like caveman", "use caveman", "less tokens", "be brief", or invokes /caveman. Also auto-triggers when token efficiency is requested.

Quality

Content

100%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

An exemplar of conciseness and actionability that practices what it preaches: every token earns its place, the guidance is concrete with worked examples, and structure is clean. Well-suited to its single-purpose scope.

DimensionReasoningScore

Conciseness

Written in its own terse caveman register; no padding, no explanation of concepts Claude already knows; every line earns its place.

5 / 5

Actionability

Concrete output pattern `[thing] [action] [reason]`, an explicit Not/Yes contrast, and per-level worked examples across two real scenarios give copy-ready guidance.

5 / 5

Workflow Clarity

Single-action skill that is unambiguous; the Auto-Clarity section supplies an explicit checkpoint (drop caveman for warnings/irreversible ops, then resume), satisfying validation for the risky case it covers.

5 / 5

Progressive Disclosure

A simple under-50-line single-purpose skill with no need for external references, organized under clear headers (Persistence, Rules, Intensity, Auto-Clarity, Boundaries) — meets the simple-skill exception for the top anchor.

Description

91%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong, well-structured description that clearly states capability and triggers with comprehensive natural keywords. Minor overlap risk on generic brevity terms keeps distinctiveness just below the top anchor.

DimensionReasoningScore

Specificity

Names the domain and several concrete behaviors ('Cuts token usage ~75%', 'speaking like caveman', 'keeping full technical accuracy', six named intensity levels); not a 5 because it is a single-mode skill rather than a broad multi-action catalog.

4 / 5

Completeness

Explicitly answers both 'what' (ultra-compressed mode cutting ~75% of tokens while keeping technical accuracy) and 'when' with concrete trigger phrases and an auto-trigger condition.

5 / 5

Trigger Term Quality

Comprehensive natural trigger phrases including synonyms, a slash command, and indirect phrasing ('caveman mode', 'talk like caveman', 'use caveman', 'less tokens', 'be brief', '/caveman', 'token efficiency').

5 / 5

Distinctiveness Conflict Risk

Clear niche with distinctive 'caveman' triggers, but generic terms like 'less tokens' and 'be brief' create minor overlap risk with general brevity skills.
