61%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 lean, well-organized reference of mobile game development principles whose tables mostly respect token budget and contain several genuinely concrete numbers (44x44 points, 30 FPS, thermal tiers). Its weaknesses are the absence of executable guidance — many entries are abstract directives rather than instructive steps — and the dangling, meaningless 'When to Use' boilerplate at the end.
Suggestions
Convert abstract directives into actionable guidance, e.g., replace 'Limit CPU/GPU usage' with concrete techniques (frame budgeting, LOD, batching draw calls) and give measurable thresholds for the thermal trigger table.
Delete or rewrite the 'When to Use' section — 'This skill is applicable to execute the workflow or actions described in the overview' conveys nothing and wastes tokens; state actual applicability conditions.
Tighten filler table rows ('Responsive UI', 'Gestures available') or merge them with concrete values so every row carries actionable content.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is compact and table-driven with no explanations of concepts Claude already knows, so it is well above anchor 3. It falls short of anchor 5 ('every token earns its place') because of low-value rows like 'Responsive UI' and the vacuous closing 'When to Use' boilerplate ('applicable to execute the workflow or actions described in the overview'). | 4 / 5 |
Actionability | There are genuinely concrete specifics ('Minimum touch target: 44x44 points', '30 FPS often sufficient', 'Dark mode saves OLED battery', thermal trigger tiers), but much of the guidance is abstract principle with no commands or code ('Limit CPU/GPU usage', 'Throttle when hot', 'Cache and sync'). This matches 'some concrete guidance but incomplete' rather than 'mostly executable' (4). | 3 / 5 |
Workflow Clarity | This is a topical reference skill, not a multi-step process: sections are organized and coherent (so not below 3), but there is no sequence, no checkpoints, and no single unambiguous action that would earn the simple-skill exception's 5. Anchor 3 — structure present, process elements absent — is the best fit. | 3 / 5 |
Progressive Disclosure | No bundle files exist (references/, scripts/, assets/ are absent), and the ~105-line body is appropriately self-contained with clear section headers and tables — good structure with content appropriately placed (anchor 4). It is not a 5 because the body exceeds the <50-line simple-skill exception and has minor organization gaps (the redundant 'When to Use' section and heavy '---' separators). | 4 / 5 |
