Kotlin UI DSL
Use Kotlin UI DSL (com.intellij.ui.dsl.builder, "version 2") for new IntelliJ forms: dialogs, settings pages, and form-like tool-window content. panel { } returns a DialogPanel with layout, data binding, and validation wired together.
Version 1 (the com.intellij.ui.layout builder: LayoutBuilder, CellBuilder, PropertyBinding, noteRow, titledRow, ...) was removed in July 2026 — never write against it and do not copy old snippets that import it. ComponentPredicate and ValidationInfoBuilder still live in the com.intellij.ui.layout package, but they are current v2 support code, not leftovers.
For component architecture (state flow, EDT, lifecycle) apply the Swing component architecture skill; for accessibility review apply the UI accessibility skill.
