Shader Review

Reviews Godot Shader/Material implementation for known pitfalls. Triggers AFTER implementation, when code involves ShaderMaterial, set_shader_parameter, .gdshader, VisualShader, hint_screen_texture, BackBufferCopy, instance uniform, or uniform declarations. Do NOT use this skill for planning or teaching — only for post-implementation review.

Shader Review

Post-implementation reviewer for Godot shader code. Checks against known gotchas that LLMs consistently get wrong.

When to trigger

After shader-related code is written or modified. Look for:

  • ShaderMaterial, .gdshader files, VisualShader resources
  • set_shader_parameter() / SetShaderParameter() calls
  • hint_screen_texture, BackBufferCopy nodes
  • instance uniform declarations
  • Uniform type assignments in scripts

Review process

  1. Read gotchas.md
  2. Scan the implemented code against each gotcha
  3. For each hit:
    • Cite the gotcha ID (e.g. G1)
    • Show the offending code
    • Provide the fix
  4. If no hits, report clean
  5. Optionally run checklist.md static checks for automated verification

When you need specific API details, delegate to the godot-api skill.
