The instructions your model reads when the skill loads.
Audit SwiftUI view performance from a reproducible symptom to measured
remediation. Route animation design to swiftui-animation, production telemetry
to metrickit, ownership/leak analysis to ios-memgraph-analysis, navigation
behavior to swiftui-navigation, state architecture to swiftui-patterns, and
layout construction to swiftui-layout-components.
