Conciseness

The body documents inputs three times — as bullets under '## Inputs', as a table under '## Input', and as an Input JSON Schema — which is clear redundancy, and the generic multi-line/stdin aside adds boilerplate. This matches 'mostly efficient but includes some unnecessary explanation or could be tightened'; it is not a 2 because no background concepts Claude already knows are explained, and every section does carry tool-specific information.

Actionability

The 'How to Call' section gives a copy-paste-ready `unity-mcp-cli run-tool` command with example JSON, the error conditions are stated ('Returns an [Error] string when moduleName is empty or unknown'), and both input and output JSON schemas are included. It falls short of 5 only because the output schema says merely `result: string` without describing what the result string actually contains on success.

Workflow Clarity

This is a single-step tool and the single action is unambiguous: call the CLI with `moduleName` and `enabled`, with error returns documented for empty/unknown names, satisfying the simple-skill exception. It is not destructive or batch, so the validation-cap does not apply, and the documented error behavior provides a minimal feedback path.

Progressive Disclosure

There are no bundle files, and the single external pointer ('Read the /unity-initial-setup skill') is clearly signaled, but the body's own organization is flawed: duplicate Input sections ('## Inputs' vs '## Input' with overlapping content) and a '### Troubleshooting' heading nested oddly under 'How to Call'. This fits 'some structure but could be better organized'; it is not a 4 because the duplication and inconsistent heading levels are real organization gaps, not minor ones.

Specificity

The description names one concrete action — "Toggle the wrapper's local 'enabled' flag for a named profiler module" — plus an honest scope caveat ("Bookkeeping only — Unity's runtime API does not expose direct module control"). This matches the anchor 'names domain and 1-2 concrete actions, but not comprehensive'; it does not list several distinct actions that would justify a 4, and it is far more concrete than the generic domain-naming of a 2.

Completeness

The 'what' is clear and concrete, but there is no 'Use when...' clause or equivalent explicit trigger guidance, which per the judging guidelines caps completeness at 3. It is not a 2 because the 'what' is specific and even states what the tool intentionally does not do; it is not a 4 because no 'when' guidance exists at all, not even a weakly explicit one.

Trigger Term Quality

Relevant keywords like "profiler module", "enabled flag", and "Profiler window" are present, but common variations users would naturally say (e.g. specific module names such as CPU/Memory, "turn on/off a module", "instrumentation") are missing. Anchor 4's 'good keyword coverage' is not reached because synonyms and natural phrasings beyond the single 'toggle' verb are absent; it clearly exceeds the generic one-or-two-keyword level of 2.

Distinctiveness Conflict Risk

The description occupies a clear niche — toggling a wrapper's local enabled flag for named profiler modules in Unity — with distinct trigger terms unlikely to fire for unrelated skills. The explicit boundary statement ("for real module visibility use the Profiler window") further reduces confusion with neighboring capabilities, matching the 'clear niche with distinct triggers; minimal conflict risk' anchor.
