Conciseness

The same symptom→file routing map is restated four times: the Quick Reference table, the dot-format Decision Tree, the numbered Decision Tree list ("Outdated Swift patterns... -> `skills/swift-modern.md`"), and 12 Example Invocations that duplicate the table almost entry-for-entry; the Critical Patterns section then re-summarizes the referenced files. This is noticeably padded — roughly half the body is duplication — matching anchor 2. Not 1 because no section explains basic concepts Claude already knows and each unit is dense; not 3 because the dot graph and Example Invocations are wholesale duplications, not merely 'could be tightened'.

Actionability

Directives are concrete and specific ("See `skills/swift-modern.md`", "`swift-simplifier` agent — `/axiom-audit` swift-simplify"), but every referenced path is absent from the bundle — no references/ or skills/ files ship with SKILL.md — so the primary instruction cannot be executed as packaged, and there is no inline fallback content. Not 2 because the guidance gives exact paths and commands rather than high-level hints; not 4 because dangling targets are a genuine execution gap.

Workflow Clarity

The routing sequence is unambiguous and the Conflict Resolution section explicitly disambiguates overlapping triggers ("Use concurrency, NOT swift", "Use swift for ownership... Use performance if the question is COW"). Not 5 because there are no verification or feedback steps; not 3 because the sequence is clear and this routing-only skill involves no destructive or batch operations that would demand validation checkpoints.

Progressive Disclosure

References are one level deep, clearly and consistently signaled, and the body stays an overview — structurally this is good design. However, none of the five referenced files (`skills/swift-modern.md`, `skills/ownership-conventions.md`, `skills/transferable-ref.md`, `skills/deep-link-debugging.md`, `skills/tvos.md`) exist in the bundle, so the navigation cannot actually be followed. Not 4/5 because the bundle structure breaks every pointer; not 2 because the organization is strong and references are prominently signaled, not buried or inlined.

Specificity

The description names the domain ("Swift or its toolchain") and lists concrete topic nouns ("modern idioms, noncopyable types, drag and drop, debug deep links, tvOS targets"), but states no action the skill performs — there is not a single verb describing what it does. This matches anchor 2 ('names the domain but actions are minimal or generic'); not 3 because that anchor requires '1-2 concrete actions', which are absent, and not 1 because the enumerated topics are concrete rather than pure abstraction.

Completeness

The 'when' is explicit and detailed ("Use when the question is about Swift or its toolchain rather than a framework" plus five enumerated triggers), but the 'what' is entirely unstated — the skill's capability or action never appears. Not 4/5 because 'what' is missing, and not 2 because the when-clause is far richer than the vague 'Use when working with documents' anchor example, with the trigger list partially conveying scope.

Trigger Term Quality

Includes natural phrases users would actually say: "Swift", "drag and drop", "tvOS", "debug deep links", "modern idioms". Not 5 because common synonyms are missing (e.g., Transferable, ownership, ShareLink, Swift 6, SwiftUI interop); not 3 because keyword coverage is good and varied, well beyond 'some relevant keywords'.

Distinctiveness Conflict Risk

"rather than a framework" explicitly carves out SwiftUI-style questions, giving a clear language-level Swift niche with distinct triggers. Not 5 because "Swift or its toolchain" is broad and overlaps with sibling skills (concurrency, performance, SwiftUI per the body's own conflict section); not 3 because the framework exclusion actively disambiguates the most likely collision.
