# 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.
