wieslawsoltes/development-plugin-for-avalonia

A Codex AI plugin delivering specialized skills for Avalonia UI development across 12 focused domains (bootstrap, bindings, threading, styling, controls, rendering, accessibility, and testing), with dedicated migration paths from WinForms/WPF/WinUI and HTML/CSS. Pinned to Avalonia 11.3.12 with curated Avalonia 12 migration guidance, it uses a shared reference corpus and plugin manifest discovery to route broad requests into focused skill modules rather than duplicating guidance. The architecture separates repo-local skill discovery from marketplace plugin distribution, supporting both Codex working paths through `.codex-plugin/plugin.json` manifests and local testing via `.agents/plugins/marketplace.json`.
