66%Weight 40%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
A well-organized, single-purpose tool document whose calling convention and behavior are clear, but it is held back by redundant triple-statement of the inputs and a primary code example whose placeholder values are invalid against its own schema and constraints. Tightening the input documentation and showing one realistic, working invocation would raise both conciseness and actionability.
Suggestions
Fix the primary example so it is executable: show a real call such as `unity-mcp-cli run-tool screenshot-camera --input '{}'` (uses Camera.main defaults) or one with a valid AIGD.GameObjectRef (e.g. {"name": "Main Camera"}) and width/height > 0, since the current '"cameraRef": "string_value"' / '"width": 0' example violates the schema and the stated > 0 constraint.
Deduplicate the input documentation: keep the Input table and replace the 'Inputs' prose section (or vice versa), and trim the inlined $defs portion of the JSON schema to the cameraRef-relevant fields to save ~40 lines.
Add a one-line failure note for the no-camera case (what the tool returns/does when Camera.main and Camera.allCameras are both empty), since the fallback chain is described but its endpoint is not.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is mostly efficient, but the same input information appears three times: the 'Inputs' prose, the 'Input' table, and the 60-line inlined 'Input JSON Schema' ($defs for GameObjectRef, EntityId, System.Type) largely duplicate each other. The generic CLI boilerplate (input-file, stdin heredoc, troubleshooting) also repeats per-tool scaffolding rather than tool-specific knowledge. | 3 / 5 |
Actionability | The 'How to Call' section gives the exact CLI command and concrete fallbacks (npx, --input-file, stdin), but the primary example is not executable as written: '"cameraRef": "string_value"" contradicts the schema (cameraRef must be an AIGD.GameObjectRef object with required instanceID) and '"width": 0' / '"height": 0' violate the body's own rule 'Must be > 0'. No working invocation with realistic values (or an empty-input call using Camera.main defaults) is shown. | 3 / 5 |
Workflow Clarity | This is a simple single-task skill — invoke one CLI tool and receive an image — and that single action is unambiguous, with the 'Behavior' section clearly describing the internal render/readback/restore sequence. The Troubleshooting section covers the main failure mode (CLI not found → npm install -g / npx), giving an explicit recovery path. | 5 / 5 |
Progressive Disclosure | There are no bundle files (references/, scripts/, assets/ all absent), so the skill is self-contained with well-organized sections (Inputs, Behavior, How to Call, Troubleshooting, Input, Output) and nothing buried. It falls short of a 5 only because the ~60-line JSON schema block is inlined where a leaner summary (or a one-level reference) would keep SKILL.md closer to an overview. | 4 / 5 |
