Generates custom Shader Graph nodes from HLSL code. Use when the user wants a new Shader Graph node or to make existing HLSL work as a reflected function node.

## Install

```sh
git clone https://github.com/Unity-Technologies/skills /tmp/skills && ln -s /tmp/skills/skills/shader-graph-create-custom-node ~/.claude/skills/shader-graph-create-custom-node
```

## From README

Generating a custom Shader Graph node Step 1: Generate an HLSL function definition The function must be preceded by the preprocessor define UNITYEXPORTREFLECTION Step 2: Decorate with Shader Graph hint tags See resources/allhints.hlsl for all valid hint tags and patterns C\#-style documentation tags are supported outside of funchints or paramhints blocks Required function hints: sg:ProviderKey sg:SearchCategory sg:SearchTerms sg:DisplayName Step 3: Write the code to an asset Search the project for a ShaderInclude asset (.hlsl) that already contains custom Shader Graph nodes If a matching asset exists, show the user its current contents and ask for confirmation before appending the new code If no matching asset exists, create a new .hlsl asset Ensure the file begins with \#include "ShaderApiReflectionSupport.hlsl"
