This Skill prevents frustrating Godot shader bugs by reviewing newly implemented shader and material code for known engine pitfalls that often fail silently.
Use the shader-review skill after your Godot shader code is implemented to have it scan the codebase for known shader/material pitfalls and return an issues-and-fixes report.

To catch silent Godot shader bugs, review your implemented .gdshader and ShaderMaterial code against known engine gotchas. This process scans for uniform type mismatches, shared material state bleeding, and incorrect hint_screen_texture usage to prevent incorrect rendering.
Your set_shader_parameter call causes shared material state bleeding because mutating a base ShaderMaterial affects all instances using it. Reviewing your code for this gotcha identifies the mutation risk and recommends fixes like using instance uniforms for per-object overrides.
Reviewing Godot instance uniform declarations involves scanning your .gdshader code to verify variable scope and ensure set_shader_parameter calls align with instance-level expectations. This detects incorrect uniform declarations that cause silent rendering failures.
The best way to check hint_screen_texture usage is to scan your shader code for matching gotchas regarding incorrect screen texture behavior and BackBufferCopy requirements. This identifies problematic snippets and provides targeted fixes for your specific rendering context.
Yes, the shader review process works with VisualShader nodes in Godot 4. It scans implemented VisualShader and .gdshader code for common engine gotchas, citing specific gotcha IDs with offending snippets and recommended fixes to align with Godot 4.x behavior.
You should run a Godot shader compilation verification checklist after implementing shader-related code changes to verify static and runtime checks. This ensures your ShaderMaterial compiles correctly and detects any remaining rendering bugs before shipping.
