This is a moderately well-structured mobile design skill that provides genuinely useful platform-specific knowledge, concrete anti-patterns, and executable code examples. Its main weaknesses are: references to 8+ required files that don't exist in the bundle, some verbosity in philosophical framing, and a workflow that lacks explicit sequencing and feedback loops between its many sections. The anti-pattern tables and platform defaults are the strongest elements.
Suggestions
Provide the referenced bundle files (mobile-design-thinking.md, touch-psychology.md, etc.) or remove the 'REQUIRED' enforcement language — currently the skill demands reading files that don't exist.
Add explicit workflow sequencing: number the major sections as sequential steps and add a feedback loop for when MFRI scores are too low or checkpoint items can't be filled.
Trim philosophical framing (the 'Final Law' quote, 'Mobile is NOT a small desktop', 'Think constraints first, aesthetics second') — these don't add actionable value for Claude.
Remove the 'When to Use' section at the bottom as it's a meaningless placeholder that adds no value.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill contains useful mobile-specific knowledge Claude wouldn't inherently know (platform defaults, anti-patterns, performance patterns), but includes unnecessary philosophical framing ('Mobile is NOT a small desktop', 'Final Law' quotes), redundant emphasis markers, and some concepts Claude already understands (what Fitts' Law is, that fingers aren't cursors). The tables are efficient but the overall document could be tightened by ~30%. | 3 / 5 |
Actionability | Provides concrete, executable code examples for React Native FlatList and Flutter patterns, specific touch target sizes, clear anti-pattern tables with alternatives, and a usable checklist. Minor gaps: the MFRI scoring system is somewhat abstract and the checkpoint template is more of a form than executable guidance. The framework decision tree and platform defaults are highly actionable. | 4 / 5 |
Workflow Clarity | There's a clear sequence implied (assess MFRI → ask questions → read files → fill checkpoint → design/code → release checklist), but the workflow is spread across sections without explicit sequencing between them. The release checklist provides validation, but there's no feedback loop for what happens when checks fail. The mandatory checkpoint in section 8 is a good validation step but lacks error recovery guidance. | 3 / 5 |
Progressive Disclosure | The skill references 8+ external files (mobile-design-thinking.md, touch-psychology.md, platform-ios.md, etc.) which is good progressive disclosure design, but none of these files exist in the bundle. The references are clearly signaled in tables, but without the bundle files, the skill is incomplete — critical content like 'touch-psychology.md' and 'mobile-performance.md' are marked REQUIRED but unavailable. The main file itself is quite long (~200 lines) and some sections (anti-pattern tables) could potentially be in reference files. | 3 / 5 |
