64%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This skill excels at progressive disclosure with a well-organized overview and extensive reference index, making it easy to navigate Apple's technology guidelines. However, it lacks concrete, executable guidance—there are no code examples, specific API patterns, or implementation snippets that would make the principles immediately actionable. The workflow is implicit rather than explicitly sequenced, which is acceptable for a design guidance skill but could be improved with clearer decision-tree logic for selecting and applying the right technology guidelines.
Suggestions
Add concrete examples for at least the most common technologies (e.g., a sample Apple Pay button implementation, a VoiceOver label example, a Sign in with Apple button placement) to improve actionability.
Define an explicit workflow sequence: 1. Check context file → 2. Identify which technology applies → 3. Consult specific reference → 4. Validate against key principles → 5. Produce output in specified format.
Remove the generic 'When to Use' section at the bottom, which adds no value and wastes tokens.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is mostly efficient, with well-structured principles that avoid over-explaining concepts Claude already knows. Minor verbosity in some principle descriptions (e.g., 'Health data is deeply personal' is slightly padded), and the 'When to Use' section at the bottom is generic filler. The reference table is appropriately concise. | 4 / 5 |
Actionability | The skill provides high-level design principles and a reference index but lacks concrete, executable guidance. There are no code examples, specific API calls, or copy-paste ready implementations. The 'Output Format' section gives a useful structure for responses, and the principles are specific enough to guide decisions, but the guidance remains at the level of design direction rather than executable steps. | 3 / 5 |
Workflow Clarity | The workflow is implicit rather than explicit: check context file → ask questions → consult references → produce output in specified format. The 'Questions to Ask' and 'Output Format' sections provide some structure, but there's no explicit sequenced workflow with validation checkpoints. For a design guidance skill this is somewhat acceptable, but the lack of a clear step-by-step process (e.g., when to consult which reference, how to validate recommendations against HIG) leaves gaps. | 3 / 5 |
Progressive Disclosure | Excellent progressive disclosure structure. The main file provides concise key principles as an overview, with a comprehensive reference index table pointing to 28 specific reference files organized by technology. References are one level deep, clearly signaled with descriptive topic and key content columns, and the file paths are consistent and well-organized. | 5 / 5 |
