The body is dense and mostly load-bearing (concrete grep patterns, defect categories, severity tables) without explaining known concepts, but the full output-format template and dual rating tables add length that could be trimmed without losing clarity.

Detection guidance is concrete — exact grep strings like "NavigationStack", ".fullScreenCover" and explicit search steps — but the per-category "Fix" lines are one-line abstract guidance ("Add dismiss button or cancel action") rather than executable code.

A clear five-phase sequence (map → detect → reason → cross-reference → score) with explicit verification checkpoints ("use Read to verify the surrounding context before reporting", "Require evidence from the Phase 1 map — don't speculate") and a false-positive list as a feedback guard.

There are no bundle files and the entire skill — all 11 detection categories, four phase tables, and the output template — lives inline in one ~250-line SKILL.md; sections are well-organized but content that could be split into a reference file is monolithic.

The description names the domain ("UX audit of their iOS app") and specific defect types ("dead-end views, dismiss traps, missing empty states"), but it never states a concrete capability verb; the action is only implied via the trigger "wants a UX audit" rather than an explicit "Detects/audits…" statement.

The "when" is explicit ("Use when the user mentions…"), but the "what does this do" is only implied through the trigger clause rather than stated as a distinct capability, so it does not clearly answer both.

It lists natural terms a user would say — "UX flow issues", "broken user journeys", "UX audit" — alongside specific defect phrasings, giving good coverage of likely user phrasings.

It carves a clear niche — iOS user-journey/UX-flow auditing — with distinctive triggers ("dismiss traps", "dead-end views") that are unlikely to fire for unrelated skills.
