Conciseness

The body is exemplary for token efficiency: 'Respond terse like smart caveman. All technical substance stay. Only fluff die.' Rules are compressed to functional drop-lists ('Drop: articles (a/an/the), filler (just/really/basically/actually/simply)...') with zero explanation of concepts Claude already knows. Lean throughout; every token earns its place.

Actionability

Fully actionable for an instruction-only skill: concrete drop-lists, an explicit output pattern ('[thing] [action] [reason]. [next step].'), bad/good before-after examples, a complete intensity table, worked per-level examples for two real prompts, and an executable auto-clarity example with SQL. Guidance is copy-ready and covers the common cases.

Workflow Clarity

A simple single-purpose skill whose single action is unambiguous: default level ('Default: **full**. Switch: /caveman lite|full|ultra.'), persistence rules ('ACTIVE EVERY RESPONSE. No revert after many turns.'), an explicit off-switch ('stop caveman' / 'normal mode'), and clear drop/resume conditions for risky moments ('Drop caveman when: Security warnings, Irreversible action confirmations... Resume caveman after clear part done.'). No destructive or batch operations, so the validation cap does not apply.

Progressive Disclosure

No bundle files exist and none are needed at this size; there are no references to verify. Sections (Persistence, Rules, Intensity, Auto-Clarity, Boundaries) are well-organized and flat, with no inlined content that belongs in a separate file — matching the simple-skill guideline for a self-contained skill.

Specificity

Names concrete capabilities: 'Cuts token usage ~75% by speaking like caveman while keeping full technical accuracy' and enumerates all six intensity levels (lite, full, ultra, wenyan-lite, wenyan-full, wenyan-ultra). Not 5 because scope boundaries (code/commits/PRs stay normal) are omitted, leaving minor gaps in coverage.

Completeness

Explicitly answers both what ('Ultra-compressed communication mode. Cuts token usage ~75%... keeping full technical accuracy. Supports intensity levels:...') and when ('Use when user says "caveman mode"... or invokes /caveman. Also auto-triggers when token efficiency is requested.') with concrete trigger phrases — a direct match for the top anchor.

Trigger Term Quality

Good natural-phrase coverage: '"caveman mode"', '"talk like caveman"', '"use caveman"', '"less tokens"', '"be brief"', '/caveman', and 'token efficiency'. Not 5 because a few natural synonyms users would plausibly say ('be concise', 'terse', 'shorter answers', or Chinese triggers for the wenyan variants) are missing.

Distinctiveness Conflict Risk

The 'caveman' niche and its dedicated triggers are clearly distinct, but the generic terms 'be brief', 'less tokens', and 'token efficiency' create minor overlap risk with general brevity/efficiency requests. Mostly distinct with minor overlap, matching anchor 4 rather than the minimal-conflict anchor 5.
