Conciseness

The body is a dense symptom-to-file routing table plus conflict rules that assumes Claude's competence and explains nothing it already knows. Minor trims remain: the dot decision tree largely duplicates the Quick Reference table, and "You MUST use this skill for ANY macOS-specific development…" restates the frontmatter description.

Actionability

Mostly concrete routing — e.g. "Another team's app or app group container access denied without a prompt (`OS27`)" maps to an exact file, and rows like "See `skills/sandbox-and-file-access.md`" give unambiguous pointers. The gap keeping it from a 5 is the auditor block, which only says "Available: `axiom-audit-touch`" without specifying how to invoke it.

Workflow Clarity

The Decision Tree provides a clear branching sequence and the Conflict Resolution section gives explicit tie-break rules ("Use axiom-macos for macOS-only concerns… Use axiom-swiftui for cross-platform SwiftUI"). No validation checkpoints exist, though none are needed for a read-only router, and the auditor invocation is underspecified — so it sits at 4 rather than 5.

Progressive Disclosure

The body is a pure overview: every detailed topic sits behind a clearly signaled, one-level-deep reference ("See `skills/windows.md`", "See `skills/direct-distribution.md`", cross-suite routes labeled by suite), and nothing that belongs in a separate file is inlined. Navigation via the symptom table, cross-suite routes, and decision tree is easy.

Specificity

Lists several specific areas — "windows, menus, sandboxing, distribution, AppKit bridging or modernization (control events, state restoration, concentric corners), touch input" — with only minor gaps (e.g., notarization and Catalyst are absent). It stops short of a 5 because capabilities are phrased as topic areas rather than concrete actions like "extract" or "fill forms".

Completeness

"Use when building ANY macOS app" is an explicit and specific when-clause, and the enumerated topic list conveys scope. It is not a 5 because the 'what' is implied by the topic list rather than explicitly stated as concrete actions or deliverables.

Trigger Term Quality

Natural terms users would say are well covered: "macOS app", "windows", "menus", "sandboxing", "AppKit", "touch input", "SwiftUI". A few common variations are missing ("notarize", "Mac app", "menu bar", "Catalyst"), keeping it below the comprehensive synonym coverage of a 5.

Distinctiveness Conflict Risk

"macOS-specific SwiftUI patterns" plus AppKit/sandbox/distribution terms carve a clear niche distinct from sibling suites. The breadth of "ANY macOS app" creates minor overlap risk with closely related skills like axiom-swiftui, so it does not reach the minimal-conflict clarity of a 5.
