Quality

Content

100%

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

This is an exceptionally well-crafted skill that embodies its own principles — it's concise, actionable, and clearly structured. The intensity level table with parallel examples across all six modes is particularly effective, giving Claude exact behavioral templates. The Auto-Clarity section showing when to break out of caveman mode for safety-critical situations demonstrates thoughtful boundary design.

DimensionReasoningScore

Conciseness

The skill practices what it preaches — it's lean, uses tables and examples efficiently, and never explains concepts Claude already knows. Every section earns its place with no filler or unnecessary context.

3 / 3

Actionability

Provides concrete before/after examples at every intensity level, specific rules for what to drop and keep, exact trigger phrases, and clear patterns to follow. The examples are directly usable as templates for behavior.

3 / 3

Workflow Clarity

For a behavioral/communication skill (not a multi-step process), the workflow is clear: activation triggers, persistence rules, intensity switching via /caveman command, auto-clarity exceptions, and explicit deactivation conditions are all well-sequenced and unambiguous.

3 / 3

Progressive Disclosure

For a standalone skill under 80 lines with no need for external references, the content is well-organized into logical sections (Rules, Intensity, Auto-Clarity, Boundaries) with clear headers and a table for quick reference. No bundle files are needed.

Description

100%

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

This is a strong skill description that clearly communicates what the skill does (compressed communication with specific intensity levels), when to use it (with explicit trigger phrases), and occupies a very distinct niche. The description is concise yet comprehensive, with excellent trigger term coverage. It uses proper third-person voice throughout.

DimensionReasoningScore

Specificity

Lists multiple concrete capabilities: cuts token usage ~75%, maintains technical accuracy, supports specific intensity levels (lite, full, ultra, wenyan variants). These are specific, actionable details about what the skill does.

3 / 3

Completeness

Clearly answers both 'what' (ultra-compressed communication that cuts tokens ~75% while keeping technical accuracy, with multiple intensity levels) and 'when' (explicit 'Use when' clause with specific trigger phrases and auto-trigger condition).

3 / 3

Trigger Term Quality

Excellent coverage of natural trigger terms: 'caveman mode', 'talk like caveman', 'use caveman', 'less tokens', 'be brief', '/caveman', and 'token efficiency'. These are phrases users would naturally say when wanting this behavior.

3 / 3

Distinctiveness Conflict Risk

Highly distinctive niche — 'caveman mode' communication style with specific intensity levels is unlikely to conflict with any other skill. The trigger terms are unique and specific to this particular behavior.
