Миграция IdeaVim-плагинов на @VimPlugin API

engineering

extensions-api-migration is a Claude Code skill that helps migrate IdeaVim extensions from the legacy VimExtensionFacade API to the new annotation-based API using the `@VimPlugin` annotation. It targets authors of IdeaVim plugins and contributors who need to update existing extension code to follow current development patterns. IdeaVim is a Vim engine for JetBrains IDEs — including IntelliJ IDEA, PyCharm, GoLand, CLion, WebStorm, and others — so keeping extension APIs up to date is essential for compatibility. This skill is useful when refactoring Java-based plugin code to align with the modern IdeaVim extension model.
