Conciseness

The body contains no concept explanations and every line routes somewhere, but the same symptom-to-file mapping is repeated four times across the Quick Reference table, the dot digraph, the numbered Decision Tree, and Example Invocations. That is noticeable redundancy that could be cut roughly in half, matching 'mostly efficient but includes some unnecessary explanation or could be tightened' rather than the lean anchor 5.

Actionability

As an instruction-only router, the guidance is concrete and directly executable: exact symptom strings and API names map to exact file paths, and Conflict Resolution gives explicit precedence rules ('Try uikit FIRST', 'Only use performance if...'). It falls short of fully executable because pointers like 'skills/uikit-bridging.md' and 'axiom-audit-resize' do not resolve anywhere in this bundle, and line 149 reads 'axiom-audit-resize (or axiom-audit-resize)', a literal self-duplicate.

Workflow Clarity

The routing workflow is clearly sequenced: a prioritized numbered decision tree (0/0b/0c, 1, 2, 2b...) with an explicit catch-all for pure-SwiftUI questions, plus conflict-resolution ordering rules. No validation checkpoints apply (no destructive or batch operations), so this sits at anchor 4 — clear sequence, minor gaps such as three parallel routing representations that a reader must reconcile.

Progressive Disclosure

The design is textbook router structure — a symptom table, a decision tree, and well-signaled one-level-deep references — but the actual bundle contains no files at all: none of the ~15 referenced 'skills/*.md' paths (nor an 'axiom-audit-resize' target) exist alongside SKILL.md, so the disclosure chain cannot be followed or verified from the skill directory.

Specificity

The description enumerates several concrete task areas — 'bridging UIKit and SwiftUI', 'modernizing UIKit apps (scene lifecycle, resizability)', 'debugging Auto Layout, Combine, TextKit, PencilKit, or UIKit animations' — which are specific and domain-grounded, matching the 'lists several specific actions; minor gaps in coverage' anchor. It falls short of 5 because it names task areas rather than stating concrete capabilities of the skill itself.

Completeness

The 'when' is explicit and strong ('Use when bridging... debugging...') but the 'what' is never stated — the description is entirely a trigger clause with the skill's actual capability (reference guides and debugging recipes) only implied by the topic enumeration. This sits between anchor 2 ('only when present without what') and anchor 4 (both present), landing on 3.

Trigger Term Quality

'UIKit', 'SwiftUI', 'Auto Layout', 'Combine', 'TextKit', 'PencilKit', 'scene lifecycle', 'resizability', 'animations' are the natural terms iOS developers would say, giving good keyword coverage. Not 5 because a few common user phrases are missing (e.g., 'UIViewRepresentable', 'UIHostingController', 'Unable to simultaneously satisfy constraints').

Distinctiveness Conflict Risk

The UIKit-vs-SwiftUI niche is clear and the scope is well-bounded ('bridging', 'UIKit apps', 'UIKit animations'), but 'Combine' and 'PencilKit' standing alone could pull in pure concurrency or drawing questions that belong to sibling skills — the body itself needs a Conflict Resolution section for exactly these overlaps, confirming minor overlap risk with closely related skills (anchor 4).
