Mostly lean with no concept explanations, but the meaningless "nothing" input parameter (empty description, schema entry) and the dual listing of the six fields (## Fields plus the Output JSON Schema) are tightening opportunities; it is not 3 because not every token earns its place, and not 1 because there is no padding or concept teaching.

Provides a copy-paste-ready executable command (unity-mcp-cli run-tool ...) plus file and stdin variants and a concrete troubleshooting fix, matching the fully-executable anchor.

This is a single, unambiguous read-only operation, so per the simple-skill guidance it qualifies for 3; the How-to-Call and Troubleshooting sections give a clear, low-risk path with no destructive steps needing validation.

Well-organized single-file sections (Fields, How to Call, Input, Output) with one clearly-signaled one-level reference (the /unity-initial-setup skill) and no nested references; it is not below 3 because nothing is monolithic or buried.

Lists multiple concrete return values — "frame timing, FPS, vsync, target frame rate, threading mode, and graphics device type" — each tied to specific Unity APIs, matching the multi-action anchor.

Clearly states what the skill returns, but lacks any "Use when..." clause or equivalent explicit trigger guidance, so per the guidelines completeness is capped at 2 rather than reaching 3.

Includes natural terms a Unity user would say (FPS, frame timing, vsync, frame rate, graphics device type) with good coverage; it is not above 3 since no colloquial variants are added.

The Unity rendering-stats niche with specific field/API names is clearly distinguishable and unlikely to trigger for unrelated skills; it is not below 3 because the scope is unambiguous.
