The body avoids explaining concepts Claude already knows, but the Decision Tree (dot graph) duplicates the Quick Reference table's symptom-to-file mappings, and the Automated Scanning section overlaps the auditor launches — two parallel routing structures that could be collapsed.

Routing guidance is concrete and copy-paste ready: exact agent names ('Launch swiftui-architecture-auditor'), exact slash commands ('/axiom:audit swiftui-performance'), and exact file paths; an instruction-only router need not supply code when guidance is this actionable.

The decision tree gives clear diagnostic sequencing, and the 'still broken after debugging -> debugging-diag.md' / 'nav -> nav-diag.md' pattern is an explicit escalation feedback loop; the numbered Conflict Resolution sequence adds a try-first-then-escalate flow.

SKILL.md is a pure overview routing to one-level-deep, well-signaled references via the Quick Reference table and 'See skills/X.md' pointers, with no nested 2+ level chains; the cross-suite references are explicitly flagged ('Homed in another suite') rather than broken.

Lists multiple concrete actions ('building, fixing, or improving') and concrete sub-domains ('views, navigation, layout, animations, performance, architecture, gestures, debugging, iOS 26 features'), matching the 'lists multiple specific concrete actions' anchor.

Explicit 'Use when ...' clause supplies the trigger (when) while the enumerated actions and domains supply the what; the guideline only caps at 2 when a 'Use when' clause is missing, and it is present.

Natural developer-facing terms ('SwiftUI UI', 'views', 'navigation', 'layout', 'animations', 'gestures', 'debugging', 'iOS 26') are exactly what a user would say when needing this skill, giving good coverage.

Clearly scoped to SwiftUI with a distinct niche and trigger; the imperative 'Use when' form is the canonical third-person trigger, not second person, so no voice penalty applies.
