Conciseness

The body is dense and high-signal — exact grep patterns, per-finding Issue/Fix pairs, no explanations of concepts Claude already knows — matching anchor 4's 'minor instances that could be trimmed' (e.g., Cross-Auditor overlap notes repeated across findings 2, 3, and 10, and the tool-use mandate restated in Phase 3). It is not a 5 because some repetition and rationale prose could be tightened without losing guidance.

Actionability

Every phase gives copy-paste-ready commands: literal grep patterns (e.g. `UIScreen\.main\.bounds`, `safeAreaInsets\.(left|right)\s*\*\s*2`), exact API names for fixes (`windowScene.sizeRestrictions?.minimumSize`, `panRecognizer.allowedScrollTypesMask = .all`), and a concrete validation command (`xcui resize sweep --sizes <breakpoints> --assert-id <id>`). Per the rubric's instruction-skill note, the absence of full code blocks is not penalized since the guidance is fully executable.

Workflow Clarity

Phases 1–5 are clearly sequenced with explicit validation checkpoints and feedback loops: "use Read to verify the surrounding context before reporting", "verify the translation against a known-positive string before trusting empty results", "Require evidence from the Phase 1 map — don't speculate", and present-the-map-before-proceeding. This matches anchor 5's explicit validation steps and error-recovery loops.

Progressive Disclosure

Sections are well organized with clearly signaled one-level-deep references to sibling skills ("axiom-uikit (skills/uikit-modernization.md)", "axiom-graphics (skills/resizable-rendering.md)"), but no bundle files exist in this skill and the ~150 lines of anti-pattern detail (Phase 2) could plausibly live in a reference file. This matches anchor 4's 'good structure, minor organization gaps' rather than 5's clean overview-with-references split.

Specificity

The description names concrete check areas ("window resizing support", "scene-lifecycle migration checking", "preparing an app for the 27-cycle resizing model") but never states what the skill actually does (audit/detect/report violations), matching anchor 3's domain-plus-limited-actions level. It is not a 4 because no explicit list of performed actions is given, and not a 2 because the check areas are concrete rather than generic.

Completeness

An explicit "Use when the user mentions…" clause answers *when* concretely, but the *what* is only implied by the trigger list (readiness checking, preparation) rather than explicitly stated. This sits between anchor 2 (only 'when' without 'what') and anchor 4 (both present); the rich, explicit trigger list places it at 3 rather than 2.

Trigger Term Quality

Comprehensive natural trigger phrases — "window resizing support", "resizable-window readiness", "iPhone Mirroring compatibility", "iPhone Duo readiness" — including synonyms users would naturally say, matching the comprehensive-coverage anchor. Neighboring anchors lack either the synonym spread or the niche specificity shown here.

Distinctiveness Conflict Risk

The description carves a clear niche (27-cycle resize readiness for UIKit/configuration code) with distinct triggers ("iPhone Mirroring", "iPhone Duo") that minimal other skills would claim. It is not a 4 because even the closely related SwiftUI layout-auditor territory is distinguishable from these triggers.
