Agent skill
development-plugin-for-avalonia
Repo-local umbrella skill for building, reviewing, designing, porting, and migrating Avalonia applications with modern XAML/C# patterns on Avalonia 11.3.12. Use when working inside this repository and the request is broad Avalonia work; route quickly to the focused plugin skills for startup, bindings, styling, controls, layout, rendering, testing, design systems, or HTML/WinForms/WPF/WinUI/Avalonia 12 migration work.

Development Plugin for Avalonia
Use this as the repo-local entrypoint when Codex is operating inside this repository.
This wrapper keeps repo-local skill discovery separate from plugin skill discovery:
- repo-local discovery entrypoint:
.agents/skills/development-plugin-for-avalonia/SKILL.md - plugin manifest:
../../../.codex-plugin/plugin.json - plugin skills:
../../../skills/ - shared references:
../../../references/
Load the canonical umbrella workflow from:
../../../SKILL.md
Then follow the routing rules from ../../../SKILL.md instead of copying the full routing table here. The focused plugin skills under ../../../skills/ and the shared references under ../../../references/ remain the actual implementation surface.
Keep default guidance pinned to Avalonia 11.3.12 and treat Avalonia 12 work as an explicit migration lane.
