Conciseness

The body is dense, rule-style writing without padded prose, but the ~70-line Review Checklist section restates the Core Guidelines bullets nearly verbatim (e.g., '@State properties are private', 'ForEach uses stable identity'), which is significant duplication that could be tightened. This fits anchor 3 ('mostly efficient but includes some unnecessary explanation or could be tightened') better than anchor 4, where trimming would be minor rather than removing an entire redundant section.

Actionability

Concrete, specific guidance throughout: exact property-wrapper rules, named modifiers ('.animation(_:value:)', 'glassEffectID' with '@Namespace'), a debug command ('Self._printChanges()'), and one copy-paste-ready Liquid Glass code block with an #available fallback. Not anchor 5 because common state-management and animation patterns lack inline code examples (they are delegated to reference files), leaving minor gaps in executable coverage.

Workflow Clarity

The three workflows (review/improve/implement) are clearly sequenced by user intent, each with an ordered checklist of steps and a final Review Checklist section acting as validation checkpoints, plus '#available' fallback handling. It falls short of anchor 5 because there is no explicit feedback loop (e.g., 'after fixes, re-run the checklist') and no guidance on prioritizing which issues to fix first.

Progressive Disclosure

Excellent structure: an overview, a decision tree routing to one-level-deep references that are clearly signaled inline and cataloged in a dedicated References section with per-file descriptions. However, the 14 cited 'references/*.md' files are not present in the bundle (no references/ directory exists), so the navigation as shipped is broken and cannot be verified, keeping this below anchor 5.

Specificity

Names concrete actions ('Write, review, or improve SwiftUI code') and four named focus areas ('state management, view composition, performance, and iOS 26+ Liquid Glass adoption'), comparable to the anchor-4 example of several specific actions with minor gaps. It falls short of a 5 because 'following best practices' is slightly generic and covered sub-topics like accessibility and navigation are absent, while it is clearly above anchor 3's '1-2 concrete actions'.

Completeness

Explicitly answers both what ('Write, review, or improve SwiftUI code following best practices for state management, view composition, performance, and iOS 26+ Liquid Glass adoption') and when ('Use when building new SwiftUI features, refactoring existing views, reviewing code quality, or adopting modern SwiftUI patterns') with concrete trigger phrases, matching the anchor-5 example pattern. Not anchor 4 because the when-clause is fully explicit with multiple concrete triggers, not merely adequate.

Trigger Term Quality

Good natural keyword coverage: 'building new SwiftUI features', 'refactoring existing views', 'reviewing code quality', 'adopting modern SwiftUI patterns', plus 'SwiftUI', 'state management', 'performance', 'Liquid Glass'. A few natural terms are missing (e.g., 'Swift', 'SwiftUI views', 'iOS app UI'), so it fits anchor 4 rather than anchor 5's comprehensive synonym coverage, but it is well above anchor 3's partial coverage.

Distinctiveness Conflict Risk

The SwiftUI/Liquid-Glass niche is clear and mostly distinct, but the trigger 'reviewing code quality' is broad and creates minor overlap risk with general code-review skills, matching anchor 4. Not anchor 5 because that generic review trigger could fire outside SwiftUI; not anchor 3 because the domain is tightly scoped to SwiftUI and unlikely to collide with unrelated skills.
