caveman

Ultra-compressed communication mode. Cuts token usage ~75% by dropping filler, articles, and pleasantries while keeping full technical accuracy. Use when user says "caveman mode", "talk like caveman", "use caveman", "less tokens", or invokes /caveman. A one-off "be brief" is not a trigger; this mode persists until switched off.

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 concise instruction skill that practices what it preaches: concrete rules, a reusable pattern, worked examples, and an explicit safety exception for high-stakes moments. Structure is clean and appropriately scoped for a single-purpose mode.

DimensionReasoningScore

Conciseness

The body is meta-demonstratively lean ('Respond terse like smart caveman. All technical substance stay. Only fluff die.'), assuming Claude's competence with every token earning its place and no padding. Could not be tighter without losing the rule set.

5 / 5

Actionability

Concrete, executable guidance: an explicit drop list, an abbreviation list, a template pattern ('[thing] [action] [reason]. [next step].'), and worked before/after examples (React re-render, DB pooling, destructive op). Per the instruction-only scoring note, absence of code is not penalized when guidance is this specific.

5 / 5

Workflow Clarity

A single-purpose mode skill that is clear and well-organized (Persistence, Rules, Examples, Auto-Clarity Exception), qualifying for the simple-skill exception. The Auto-Clarity Exception section supplies an explicit safety checkpoint for security warnings and irreversible actions.

5 / 5

Progressive Disclosure

Under 50 lines with no need for external references, organized into well-signaled sections; per the guideline, such skills can score 5 on structure alone. No bundle files exist to verify, and none are needed.

Description

95%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 tightly written description that concretely states what the mode does, when to invoke it, and when not to, using natural trigger synonyms and a slash command. Voice is correctly third person and free of fluff.

DimensionReasoningScore

Specificity

Names the mode and several concrete actions — 'Cuts token usage ~75% by dropping filler, articles, and pleasantries while keeping full technical accuracy' — giving specific mechanisms rather than vague claims. Not a 5 because the skill is a single narrow communication mode, not a breadth of comprehensive actions.

4 / 5

Completeness

Explicitly answers both what ('Ultra-compressed communication mode. Cuts token usage ~75%...') and when ('Use when user says...') with concrete trigger phrases, and even clarifies a non-trigger ('A one-off be brief is not a trigger'). Clearly meets the top anchor.

5 / 5

Trigger Term Quality

Comprehensive natural trigger coverage with synonyms — 'caveman mode', 'talk like caveman', 'use caveman', 'less tokens', plus the '/caveman' invocation — phrases a user would naturally say. Not below 5 because both common variations and the slash command are present.

5 / 5

Distinctiveness Conflict Risk

Occupies a clear, unique niche with distinct triggers ('caveman mode', '/caveman') unlikely to fire for any other skill, so conflict risk is minimal. The negative-trigger guidance further sharpens distinctiveness.
