Quality

Content

50%Weight 40%Scale 1-5

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

The body is well-structured and mostly actionable, with executable CLI examples and thorough schemas, but it is heavily padded by duplicated JSON schema boilerplate and generic CLI usage instructions. The batch workflow also lacks a verification step, and the large inline schemas belong in a separate reference file.

Suggestions

Deduplicate the JSON schemas: define the GameObjectRef structure once (or move both schemas to a references/ file) instead of repeating the identical $defs block in the Input and Output sections.

Replace the generic unity-mcp-cli invocation boilerplate (stdin/file/pipe instructions, npm troubleshooting) with one skill-specific example, and fix the example input so gameObjectRefs is an array of refs matching the schema.

Add a verification step after duplication, e.g. re-query via gameobject-find or check the post-call Selection to confirm the duplicates exist before reporting success.

Dimension	Reasoning	Score
Conciseness	Roughly 100 of ~170 lines are two JSON schemas that repeat the identical AIGD.GameObjectRef definition verbatim, and the "How to Call"/"Troubleshooting" blockquote is generic unity-mcp-cli boilerplate unrelated to this specific skill. Noticeably verbose with several padded/duplicated sections, matching anchor 2 rather than anchor 3's mostly-efficient profile.	2 / 5
Actionability	Provides executable CLI commands, complete input/output schemas, and a concrete troubleshooting section. Falls short of 5 because the example value "gameObjectRefs": "string_value" contradicts the schema's array type, so the primary example is not copy-paste correct.	4 / 5
Workflow Clarity	The Behavior section gives a coherent sequence (resolve refs atomically, invoke DuplicateGameObjectsUsingPasteboard, mark scenes dirty) and notes duplicates are reachable via post-call Selection, but there is no verification step for confirming the batch duplication succeeded. Per the rubric guideline, a batch operation without validation/verification caps workflow clarity at 3.	3 / 5
Progressive Disclosure	Section headers (Inputs, Behavior, How to Call, Input, Output) give reasonable structure, but the ~100 lines of duplicated schema content are API-reference material inlined in SKILL.md with no bundle files or external references at all. Some structure exists, but content that should be separate is inline, matching anchor 3.	3 / 5

Description

66%Weight 40%Scale 1-5

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 concrete, third-person, and reasonably distinctive, with good natural trigger keywords. Its main gap is the absence of an explicit "when to use this skill" clause — the gameobject-find reference is a prerequisite hint rather than a trigger.

Suggestions

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

Include natural synonyms such as "copy" and "clone" alongside "duplicate" to broaden trigger term coverage.

Dimension	Reasoning	Score
Specificity	"Duplicate a batch of GameObjects in the currently opened Prefab or active Scene. Marks each affected scene as dirty after duplication" names the domain and several specific behaviors (batch duplication, scene-dirty marking, find-first dependency). Not 3 because the actions are more detailed than a bare 1-2 action listing; not 5 because coverage is limited to the duplicate operation's core actions.	4 / 5
Completeness	The "what" is clear and concrete, but there is no "Use when..." trigger clause; "Use 'gameobject-find' to locate the source GameObjects first" is prerequisite workflow guidance, not when-to-use-this-skill guidance. Per the judging guideline, a missing explicit trigger clause caps completeness at 3.	3 / 5
Trigger Term Quality	Natural terms a Unity user would say are present: "duplicate", "GameObjects", "Prefab", "Scene", "batch". Missing common synonyms such as "copy" or "clone", which keeps it below anchor 5 but above anchor 3's thin keyword coverage.	4 / 5
Distinctiveness Conflict Risk	Duplicating GameObjects in a Prefab or Scene is a clear niche with a distinct action verb, distinguishable from sibling gameobject tools. Minor overlap risk remains with closely related Unity scene-manipulation skills, so not 5.	4 / 5
