Quality

Content

65%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.

A well-structured overview skill: lean principle statements, excellent one-level-deep progressive disclosure verified against the actual bundle, and a concrete output contract. The main weaknesses are qualitative directives without executable specifics and a workflow whose sequence must be inferred from section order rather than explicit steps.

Suggestions

State the workflow as an explicit numbered sequence — check apple-design-context.md, ask only unanswered intake questions, consult the matching references/ file, then respond in the Output Format — so the flow is written rather than implied.

Inline a few executable specifics (widget size families, system update budget figures, or one worked example recommendation) so directives like 'Budget updates wisely' and 'Feature content that entices' become actionable.

Add guidance on selecting which references/ file to consult per platform, so Claude knows how to route a question about, say, watch complications vs. tvOS top shelf.

DimensionReasoningScore

Conciseness

The body is a terse, principle-per-line overview with no explanations of concepts Claude already knows, and it correctly defers detail to references. Minor trimmable padding remains: the boilerplate 'When to Use' line ('This skill is applicable to execute the workflow or actions described in the overview') and the promotional footer add tokens without value, holding it below 5.

4 / 5

Actionability

Concrete directives are present ('3-4 most common tasks', 'Deep-link on tap', 'Support multiple sizes with distinct layouts', 'Use threading and grouping') plus a five-part Output Format and intake questions, but many principles stay qualitative ('Budget updates wisely', 'Feature content that entices') with no inline specifics — no widget size families, update budget numbers, or a worked example recommendation. Not score 4 because these gaps are more than minor for an instruction-only skill.

3 / 5

Workflow Clarity

Workflow components exist — an explicit context-file checkpoint ('Check for .claude/apple-design-context.md... only ask for information not already covered'), a Questions-to-Ask intake list, and an Output Format — but the overall sequence connecting them is implicit: the sections are parallel lists rather than ordered steps, and there is no verification checkpoint on the final recommendation. Not score 2 because the pre-check step and output template give a coherent rough sequence.

3 / 5

Progressive Disclosure

A clear overview body pairs with a well-labeled Reference Index table describing each topic; all nine referenced paths match actual files in references/, and inspection of those files shows they are one level deep (external Apple URLs only, no nested local references). Navigation is easy and the split is appropriate — details live in references while the body stays an overview.

Description

56%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 clearly scopes a distinct niche with excellent natural keyword coverage across all nine component types, but it states only one generic capability ('guidance') and entirely lacks a 'Use when...' trigger clause, which caps completeness. It reads as a topic index rather than a capability-plus-trigger statement.

Suggestions

Add an explicit trigger clause, e.g., 'Use when designing or reviewing widgets, Live Activities, notifications, complications, or other Apple platform system surfaces outside the app.'

Replace the generic 'guidance' with concrete capabilities, e.g., 'Recommends the right system surface, defines content and update strategy, and specifies size variants and deep-link behavior.'

Include common synonyms and phrases users actually say: 'Dynamic Island', 'Lock Screen', 'Siri', 'Spotlight', 'iOS widgets'.

DimensionReasoningScore

Specificity

The description names the domain ('Apple HIG guidance for system experience components') and enumerates nine component types, but the only stated capability is the generic verb 'guidance' — no concrete actions like design, recommend, or evaluate. It matches 'Names the domain but actions are minimal or generic' rather than score 3, which requires 1-2 concrete actions.

2 / 5

Completeness

There is a clear 'what' (HIG guidance for nine enumerated system experience components), but no 'Use when...' clause or equivalent explicit trigger guidance, so completeness is capped at 3 per the judging guidelines. Not score 2 because the 'what' is specific and comprehensive, not vague.

3 / 5

Trigger Term Quality

Strong natural keyword coverage — 'widgets', 'live activities', 'notifications', 'complications', 'home screen quick actions', 'app clips', 'app shortcuts' are exactly the terms a user would say when needing this skill. Falls short of 5 because common variations and synonyms are missing (e.g., 'Dynamic Island', 'Lock Screen', 'Siri', 'Spotlight', 'iOS').

4 / 5

Distinctiveness Conflict Risk

The Apple HIG system-experience niche is mostly distinct thanks to the explicit component enumeration, but the body reveals closely related sibling skills (hig-components-status, hig-technologies) that overlap on widgets/Live Activities/Siri, and the description offers no trigger phrasing to disambiguate. Not 5 because 'distinct triggers' are absent; not 3 because the enumerated scope is far more specific than 'somewhat specific'.
