Conciseness

The body is dense and assumes Claude's competence — tables, one executable Swift example, a checklist, and no explanation of known concepts. However, the Pattern Selection table's "Choose when" column and the Escalation Signals bullets substantially restate the same per-pattern criteria (e.g., "Presentation logic needs an independently testable adapter" vs. "substantial presentation transformation must be tested without rendering"), which is duplication that could be trimmed. This sits between the efficient and every-token-earns-its-place anchors, noticeably above the midpoint.

Actionability

The MV Default section provides copy-paste-ready @Observable TripStore/TripList Swift code, the pattern table gives concrete selection criteria, migration steps are numbered and specific, and the Common Mistakes table pairs each mistake with a fix. Specific examples cover the common cases, matching the fully-executable anchor.

Workflow Clarity

The Decision Workflow ends with an explicit validation feedback loop ("If behavior changes, restore the fixture, fix the smallest boundary, and rerun before migrating another slice"), Migration gates removal on "no callers or tests depend on it" with behavior comparison after each slice, and a Review Checklist is provided. Sequence, checkpoints, and error-recovery loops are all present, matching the top anchor.

Progressive Disclosure

The body is an overview that clearly signals the single one-level-deep reference ("Load [Architecture Pattern Recipes](references/architecture-patterns.md) for MVVM, MVI, TCA, Clean Architecture, Coordinator, and VIPER structure"); the reference file exists and itself contains no nested file references. A table of contents aids navigation, matching the clear-overview anchor.

Specificity

"Selects, reviews, and migrates Apple-platform app architectures across MV with Observation, MVVM, MVI, TCA, Clean Architecture, Coordinator, and legacy VIPER" lists multiple concrete actions and comprehensively enumerates the pattern space it covers, matching the comprehensive-coverage anchor. Only "reviews" is slightly less concrete than the rest, which is not enough to drop to the minor-gaps anchor.

Completeness

The description explicitly answers what ("Selects, reviews, and migrates Apple-platform app architectures") and when ("Use when choosing module and dependency boundaries, escalating a feature beyond simple SwiftUI MV, planning incremental architecture migration, or auditing state ownership and test seams") with concrete trigger phrases. It matches the anchor-5 example's structure.

Trigger Term Quality

Natural user vocabulary is present throughout: "SwiftUI", "MVVM", "MVI", "TCA", "Clean Architecture", "architecture migration", "module and dependency boundaries", "state ownership", and "test seams" are exactly the phrases a Swift developer uses when asking for architectural help. This matches the comprehensive natural-terms anchor.

Distinctiveness Conflict Risk

The Apple-platform architecture niche with named patterns is largely distinct, but "dependency boundaries" and "test seams" carry minor overlap risk with closely related sibling skills (e.g., swift-testing, swift-concurrency). This fits the "mostly distinct; minor overlap risk" anchor rather than the minimal-conflict anchor.
