Conciseness

The body is efficient overall, with no explanations of concepts Claude already knows. Minor trims exist: the "## Fields" bullets duplicate the Output JSON schema descriptions, and the three-variant invocation boilerplate (inline JSON, input file, stdin) could be tightened. Not 3 because the padding is localized, not pervasive.

Actionability

The "How to Call" section gives a fully executable copy-paste CLI command, plus troubleshooting ("If unity-mcp-cli is not found... use npx unity-mcp-cli") and complete input/output schemas. Not 5 because the input example is a meaningless placeholder ("nothing": "string_value") rather than a realistic invocation.

Workflow Clarity

This is a simple, single-purpose skill and the single action — run `unity-mcp-cli run-tool profiler-capture-frame` — is unambiguous, with the main failure mode (CLI not installed) explicitly addressed in Troubleshooting. Per the simple-skill guideline, no multi-step workflow or validation is needed, and the operation is non-destructive so the validation cap does not apply.

Progressive Disclosure

Sections are well-organized (Fields, Behavior, How to Call, Input, Output) with no bundle files to reference and a clearly signaled skill-level pointer ("Read the /unity-initial-setup skill"). Not 5 because of minor organization gaps — the Fields/Output schema duplication and the interposition of How to Call's boilerplate between Behavior and Input — that keep the structure from being cleanly navigable.

Specificity

"Capture the current frame's timing info (delta time, FPS, frame counts, runtime)" enumerates several concrete data points and adds an explicit scope boundary ("Snapshot only — historical frames live in Unity's Profiler window"). It stops short of 5 because it describes a single capture action rather than multiple comprehensive actions.

Completeness

The "what" is clear (capture the current frame's timing fields), but there is no "Use when..." or equivalent trigger guidance, which caps completeness at 3 per the judging guidelines. Not 2 because the "what" is specific, not vague.

Trigger Term Quality

Natural terms users would say — "FPS", "delta time", "frame", "timing", "Profiler", "runtime" — are present. A few common variations such as "frame rate" or "performance" are missing, so it is not the comprehensive synonym coverage of a 5.

Distinctiveness Conflict Risk

It occupies a clear Unity frame-timing niche and explicitly distinguishes itself from the Profiler window ("historical frames live in Unity's Profiler window"), so conflict risk with other skills is minimal.
