Extremely lean and efficient. Uses tables for structured data, avoids explaining what Claude already knows, and every section earns its place. The caveman style itself reinforces brevity. No unnecessary padding or concept explanations.

Provides concrete triggers, exact commands, configuration examples with executable code (env var and JSON config), and clear behavioral descriptions. The tables give precise trigger-to-behavior mappings that are immediately actionable.

This is a single-purpose reference card skill with a clear, unambiguous action: display the help card. The deactivation flow, mode persistence behavior, configuration resolution order (env var > config file > full), and language rules are all explicitly stated. No multi-step destructive operations require validation checkpoints.

Content is well-organized into logical sections (Modes, Skills, Deactivate, Language, Configure, More) with a clear link to full docs at the end. For a help card skill with no bundle files, this is appropriately structured — concise overview with one external reference for deeper information.

It describes a concrete action ('Quick-reference card' and 'One-shot display') and names the domain (caveman modes, skills, commands), but doesn't list multiple specific actions beyond displaying help information.

Clearly answers both 'what' (quick-reference card for all caveman modes, skills, and commands; one-shot display) and 'when' (explicit trigger terms listed after 'Trigger:'). The when clause is explicit and well-defined.

Excellent trigger term coverage with natural phrases users would actually say: '/caveman-help', 'caveman help', 'what caveman commands', 'how do I use caveman'. These are realistic user queries with good variation.

Very distinct niche — it's specifically a help/reference card for 'caveman' functionality with unique trigger terms. Unlikely to conflict with other skills due to the specific 'caveman' domain qualifier.
