Lists multiple specific concrete actions and patterns: refactoring SwiftUI views, splitting long bodies, removing inline actions/side effects, reducing computed `some View` helpers, standardizing `@Observable` and view model initialization patterns, MV-over-MVVM data flow, stable view trees, explicit dependency injection.

Clearly answers both 'what' (refactor and review SwiftUI view files with specific architectural defaults) and 'when' (explicit 'Use when...' clause listing five concrete trigger scenarios like cleaning up views, splitting long bodies, removing inline actions, etc.).

Includes highly natural keywords a SwiftUI developer would use: 'SwiftUI view', 'subviews', 'MVVM', '@Observable', 'view model', 'dependency injection', 'refactor', 'review', 'splitting long bodies', 'side effects', 'some View'. These cover a strong range of terms users would naturally mention.

Highly distinctive — narrowly scoped to SwiftUI view refactoring with specific architectural opinions (MV-over-MVVM, stable view trees, Observation usage). Unlikely to conflict with general Swift skills, general code review skills, or other iOS development skills due to the precise domain and opinionated patterns mentioned.

The content is mostly efficient and avoids explaining basic SwiftUI concepts, but some sections are somewhat verbose—e.g., the 'Avoid' examples could be shorter, and a few guidelines repeat similar points across sections (e.g., 'prefer small subview types' appears in multiple places). The code examples earn their place but the prose surrounding them could be tightened.

The skill provides fully executable Swift code examples for each guideline, concrete 'Prefer' vs 'Avoid' patterns, and specific rules (e.g., store @Observable as @State, init pattern for view models). The workflow section gives a clear step-by-step refactoring process. Everything is copy-paste ready and directly applicable.

The 7-step workflow is clearly sequenced and covers the refactoring process well. However, there are no explicit validation checkpoints or feedback loops—step 7 says 'keep behavior intact' but doesn't specify how to verify this (e.g., run previews, check for compilation, compare before/after). For a refactoring skill that could introduce regressions, this is a notable gap.

The content is well-structured with clear headers and sections, and there's one reference to an external file (references/mv-patterns.md). However, at ~150+ lines with extensive inline code examples, some content (like the full Prefer/Avoid examples for each guideline) could be split into a reference file. The skill is borderline monolithic for its length.
