webgpu-wgsl-uniformity

What problem does it solve?

Use this Skill when WGSL shaders fail uniformity analysis or when optional language and device features need to be enabled safely. It prevents shader-creation errors caused by sampling, derivatives, barriers, or diagnostics being placed in the wrong control flow.

Core Features & Use Cases

• Uniformity Fixes: Identifies when texture sampling, derivatives, or workgroup barriers must be moved into uniform control flow.
• Directive Guidance: Explains how to place enable, requires, and diagnostic directives correctly at the top of a shader.
• Feature Gating: Helps pair shader features with host-side device checks so f16, subgroups, and other optional capabilities compile reliably.
• Use Case: Debug a fragment shader that triggers derivative_uniformity, then rewrite it so sampling is hoisted safely and the shader validates on WebGPU.

Quick Start

Ask for help fixing a WGSL shader that triggers a uniformity diagnostic, and the Skill will show the correct control-flow rewrite, directive placement, and feature gating.
