Rules and patterns for writing tests of Avalonia UI visual elements (controls, dialogs, panels). Use when creating or modifying tests for XAML controls, dialogs, or panels.

Rules and patterns for creating Avalonia UI visual elements (controls, dialogs, panels, windows). Use when creating or modifying XAML controls, dialogs, panels, or windows in this project.

Use whenever writing, reviewing, or debugging .NET/C# code that uses the BallisticCalculator NuGet package (namespace BallisticCalculator) or its Gehtsoft.Measurements unit types — even when the user doesn't name the package explicitly but is clearly doing external/interior ballistics in .NET (bullet drop, velocity, energy, windage, spin drift, time of flight, zeroing a scope) for rifles, air rifles, bows, or artillery. Covers the full public API (Ammunition, Rifle, Atmosphere, Wind, ShotPara...

Author and modify documentation for projects that use Gehtsoft's docgen utility. Use this skill whenever the user mentions docgen, .ds files, the doc/ directory of a repository, project.xml or project.proj for documentation, or wants to write/edit/build/debug API documentation in any codebase that uses docgen. Also use it whenever the user asks about generating C#, C++, or Java API documentation that follows Gehtsoft conventions, even if they don't say "docgen" explicitly.

Design a rifle-scope reticle from a plain-language description and emit it as a BallisticCalculator `.reticle` file (BXml) plus a rendered SVG preview. Covers the complete `.reticle` element/attribute specification, reticle design principles (mrad vs MOA subtension, FFP/SFP, stroke-weight hierarchy, hash-mark ladders, christmas-tree wind holds, clutter budget, BDC anchors) and worked, verified patterns for duplex, mil-dot, hash-ladder, christmas-tree, chevron, circle-dot, dense-grid and range...
