Conciseness

The body is dense prescriptive guidance with no padding and no explanation of basics Claude already knows (it never explains what SwiftUI, safe areas, or Dynamic Type are; it only states skill-specific judgments like 'Size class is an environment category, not a device detector'). Every line earns its place.

Actionability

Guidance is concrete at the API level throughout ('ViewThatFits', 'AnyLayout', 'safeAreaInset', '@ScaledMetric', 'containerRelativeFrame', 'onGeometryChange', 'layoutPriority') with a requirement-to-signal table and a ranked pattern ladder, but no inline code examples or copy-paste patterns are shown — those live in the referenced files, leaving minor gaps versus the fully-executable top anchor.

Workflow Clarity

The Diagnostic Workflow is a clearly sequenced five-step process (reproduce smallest failing configuration, inspect hierarchy, classify cause, apply narrowest fix, verify) with an explicit validation step ('Verify the original failure plus neighboring configurations') and a dedicated Review Checklist, matching the top anchor's sequence-plus-checklist pattern.

Progressive Disclosure

A clear ~120-line overview with a table of contents, and both referenced bundle files (references/layout-diagnosis.md, references/adaptive-patterns.md) exist, are one level deep, and are well-signaled with when-to-read conditions ('Read... when investigating an existing failure', 'Read... before implementing a responsive variant').

Specificity

Concrete actions are stated ('Diagnose and implement adaptive SwiftUI layouts') with enumerated dimensions (window sizes, orientation, Dynamic Type, localization, safe areas, keyboard, multitasking) and routing actions, but the action verbs themselves are only two, leaving minor coverage gaps versus the comprehensive top anchor.

Completeness

Explicitly answers both what ('Diagnose and implement adaptive SwiftUI layouts across...') and when ('Use when views clip, overlap, truncate, move off-screen, or depend on brittle fixed frames') with concrete trigger phrases, matching the top anchor exactly.

Trigger Term Quality

Natural failure phrases users would actually say are covered with effective synonyms: 'clip, overlap, truncate, move off-screen', plus 'fixed frames', 'orientation', 'Dynamic Type', 'keyboard', 'iPhone and iPad'. The neighboring anchor 4 ('a few natural terms missing') fits less well given this synonym coverage.

Distinctiveness Conflict Risk

Clear niche (cross-size adaptation and layout-failure diagnosis) with explicit negative routing ('route ordinary container selection to swiftui-layout-components and measured runtime profiling to swiftui-performance'), which minimizes conflict risk with closely related skills.
