+# WGSL Shader Development
+
+Reference for WGSL shader development, buffer alignment, uniform struct layout, and shader asset management. Load this skill when working on shader code, graphics pipelines, or buffer alignment issues.
+
+## WGSL Uniform Buffer Alignment
+
+When creating uniform buffers for WGSL shaders, struct fields must be aligned:
+
+| Type | Alignment |
+|------|-----------|
+| `f32` | 4 bytes |
+| `vec2<f32>` | 8 bytes |
+| `vec3<f32>` | 16 bytes (treated as vec4) |
+| `vec4<f32>` | 16 bytes |
+| `mat4x4<f32>` | 16 bytes (64 bytes total) |
+
+Use padding fields to match WGSL struct layout exactly. Prefer `vec4` over individual floats to avoid alignment issues.
+
+## Shader Organization
+
+Shaders live in `src/shaders/` and are embedded via `include_str!()`.
