shader-graph-create-custom-node — Claude Code skill: how to install

Q: How to install shader-graph-create-custom-node in Claude Code?

Run `npx skills add Unity-Technologies/skills --skill shader-graph-create-custom-node -a claude-code` in your terminal. This downloads the skill into `~/.claude/skills/`.

Q: Which package version does shader-graph-create-custom-node require?

It requires `com.unity.shadergraph` version 17.5.0 or newer, along with `#include "ShaderApiReflectionSupport.hlsl"` at the start of the HLSL file.

Generates custom Shader Graph nodes directly from HLSL functions. It handles reflection markup so Unity registers your shader code in the graph creation menu.

What shader-graph-create-custom-node does

The skill automates the creation of Shader Graph nodes using Unity reflection metadata. It prepends your HLSL function with UNITY_EXPORT_REFLECTION and applies the mandatory hint tags: display name, category, provider key, and search terms. Documentation in C# style can be included outside hint blocks.

Once the code is prepared, the skill targets a .hlsl asset. It checks the project for existing ShaderInclude files that already host custom nodes, showing the content to ask for confirmation before modifying anything. If no suitable file exists, it generates a fresh .hlsl asset headed by #include "ShaderApiReflectionSupport.hlsl".

Your Unity project must have the com.unity.shadergraph package at version 17.5.0 or newer. Without this minimum version, the reflection workflow fails to expose your HLSL functions inside the graph editor.

What it helps with

convert existing HLSL functions into reflected Shader Graph nodes
annotate HLSL code with search keywords and category hints for Unity
append new custom node definitions to existing ShaderInclude assets
scaffold a new HLSL include file with reflection support headers

Example prompts for the agent

Turn this HLSL noise function into a custom Shader Graph node named SimplexNoise
Expose my color correction HLSL helper as a reflected node in the Color category
Generate a custom Shader Graph node from this HLSL code and save it to our ShaderInclude asset
