Conciseness

The body documents the same 11 parameters three times — prose in "Filters"/"Response toggles", the Input table, and the Input JSON Schema — and then dumps a ~140-line raw output JSON schema with .NET type names like "System.Collections.Generic.List(com.IvanMurzak.Unity.MCP.Editor.API.TestRunner.TestLogEntry)". Most content is information-bearing (not concept re-explanation), so it clears score 2, but the redundancy and inline schema bloat mean it could be tightened considerably.

Actionability

"unity-mcp-cli run-tool tests-run --input ..." plus the --input-file and stdin heredoc forms give a mostly executable, copy-paste-ready invocation, and the Input table supplies concrete example values. The gap keeping it from 5: the primary example uses placeholders ("string_value", bare booleans) rather than one fully-real call, e.g. a real EditMode run filtered to a test class.

Workflow Clarity

For a single-tool skill the action is unambiguous, and failure/recovery paths are documented: "If any open scene is dirty... save them and retry", "Pre-existing compilation errors short-circuit the run... so the caller can fix the project first", the domain-reload Processing/resume flow, and CLI-not-found fallbacks (npm install -g / npx). Minor gaps keep it at 4: these checkpoints are scattered across sections rather than sequenced, and there is no explicit verify step for confirming tests actually ran post-reload.

Progressive Disclosure

Section structure is clear (Filters, Response toggles, Domain reloads, How to Call, Input, Output) and the /unity-initial-setup reference is one level deep, but ~160 lines of raw input/output JSON schemas are inlined in SKILL.md — content that clearly belongs in reference files given no bundle directory exists. This matches the anchor "some structure but... content that should be separate is inline" rather than 2, since structure and navigation are otherwise good.

Specificity

"Execute Unity tests (`EditMode` or `PlayMode`) and return per-test results. Supports filtering by test assembly, namespace, class, and method. Refreshes the AssetDatabase first; defers execution across domain reloads if scripts changed" — multiple specific concrete actions with comprehensive coverage of the tool's behavior, including boundary conditions (dirty scenes abort the run). No filler or vague language.

Completeness

The "what" is clearly and thoroughly answered, but there is no "Use when..." clause or equivalent explicit trigger guidance — the rubric explicitly caps completeness at 3 in that case. Not score 2 because the "what" is concrete, not vague; not score 4+ because the "when" is entirely absent rather than merely implicit.

Trigger Term Quality

Good natural keywords: "Unity tests", "EditMode", "PlayMode", "test assembly", "namespace", "class", "method" — phrases a user working in Unity would naturally say. A few common variations are missing (e.g., "run tests", "test suite", "unit tests"), so it falls just short of the comprehensive-synonyms anchor.

Distinctiveness Conflict Risk

"Execute Unity tests (`EditMode` or `PlayMode`)" with Unity-specific triggers (EditMode, PlayMode, AssetDatabase, domain reloads) carves out a clear niche with minimal overlap risk against generic test- or document-related skills. Re-checked against the 4 anchor: this is more distinct than "minor overlap risk" — the Unity-specific terminology makes mis-triggering unlikely.
