Quality

Content

72%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The body is highly actionable with a concrete CLI command and precise behavioral detail, and it is well-organized for a single-tool skill. It loses points for redundant input descriptions and a missing verification checkpoint after the batch duplication.

Suggestions

Consolidate the gameObjectRefs input into one place (drop either the Inputs list or the Input table) and trim or externalize the full JSON schemas to cut tokens.

Add a post-duplication verification step, e.g. inspect the post-call Selection to confirm the duplicates were created, since this is a batch operation.

Dimension	Reasoning	Score
Conciseness	Mostly efficient with no concept-explaining fluff, but the gameObjectRefs input is described three times (Inputs list, Input table, and a full embedded JSON schema) and the large input/output schemas add tokens that could be trimmed or referenced.	2 / 3
Actionability	Provides a copy-paste-ready `unity-mcp-cli run-tool gameobject-duplicate` command with --input, --input-file, and stdin variants, plus concrete API behavior (resolves refs on the main thread, sets Selection, invokes Unsupported.DuplicateGameObjectsUsingPasteboard, marks scenes dirty).	3 / 3
Workflow Clarity	The find-then-duplicate sequence and atomicity-on-unresolved-ref are clear, but this is a batch operation with no post-duplication verification step, so workflow clarity is capped at 2 per the batch-operations guideline.	2 / 3
Progressive Disclosure	No bundle files exist and the body is a self-contained, single-tool skill organized into clearly labeled sections (Inputs, Behavior, How to Call, Troubleshooting, schemas) with no nested references.	3 / 3

Description

82%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description is specific, actionable, and well-differentiated, naming concrete actions and natural Unity terms. Its main weakness is the absence of an explicit 'Use when...' trigger clause, leaving the when-to-use guidance only implied.

Suggestions

Add an explicit trigger clause, e.g. 'Use when the user asks to duplicate or copy GameObjects in a Prefab or Scene.'

Include common synonyms like 'copy' or 'clone' alongside 'Duplicate' to broaden natural trigger coverage.

Dimension	Reasoning	Score
Specificity	Lists multiple concrete actions — 'Duplicate a batch of GameObjects', 'Marks each affected scene as dirty after duplication', and using 'gameobject-find' to locate sources — rather than vague language.	3 / 3
Completeness	It clearly answers 'what' (duplicate batch, mark scenes dirty) but lacks an explicit 'Use when...' trigger clause; 'Use gameobject-find to locate the source GameObjects first' is a prerequisite instruction, not a when-to-use trigger, so completeness caps at 2.	2 / 3
Trigger Term Quality	Covers the natural terms a Unity user would say — 'Duplicate', 'GameObjects', 'Prefab', 'Scene' — which are exactly the keywords that would trigger this skill.	3 / 3
Distinctiveness Conflict Risk	Occupies a clear niche — duplicating GameObjects in an opened Prefab or active Scene — with distinct triggers and a named companion tool, making conflict with other skills unlikely.	3 / 3
