# Assets Shader Get Data > Get detailed data about a shader asset in the Unity project. Returns shader properties, subshaders, passes, compilation errors, and supported status. Use 'assets-find' tool with filter 't:Shader' to find shaders, or 'assets-shader-list-all' tool to list all shader names. - Skill: `idocohen560/assets-shader-get-data` (Agent Skill) - Install (CLI): `npx skillmds@latest add idocohen560/assets-shader-get-data` - Raw SKILL.md: https://api.skillmd.com/api/skills/idocohen560/assets-shader-get-data/raw - Safety review: pending - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: AI & ML - Author: IdoCohen560 (https://skillmd.com/u/idocohen560) - Updated: 2026-09-17 - Page: https://skillmd.com/skills/idocohen560/assets-shader-get-data --- # Assets / Shader / Get Data ## How to Call ```bash unity-mcp-cli run-tool assets-shader-get-data --input '{ "assetRef": "string_value", "includeMessages": "string_value", "includeProperties": "string_value", "includeSubshaders": "string_value", "includeSourceCode": "string_value" }' ``` > For complex input (multi-line strings, code), save the JSON to a file and use: > ```bash > unity-mcp-cli run-tool assets-shader-get-data --input-file args.json > ``` > > Or pipe via stdin (recommended): > ```bash > unity-mcp-cli run-tool assets-shader-get-data --input-file - <<'EOF' > {"param": "value"} > EOF > ``` ### Troubleshooting If `unity-mcp-cli` is not found, either install it globally (`npm install -g unity-mcp-cli`) or use `npx unity-mcp-cli` instead. Read the /unity-initial-setup skill for detailed installation instructions. ## Input | Name | Type | Required | Description | |------|------|----------|-------------| | `assetRef` | `any` | Yes | Reference to UnityEngine.Object asset instance. It could be Material, ScriptableObject, Prefab, and any other Asset. Anything located in the Assets and Packages folders. | | `includeMessages` | `any` | No | Include compilation error and warning messages. Default: true | | `includeProperties` | `any` | No | Include shader properties (uniforms) list. Default: false | | `includeSubshaders` | `any` | No | Include subshader and pass structure. Default: false | | `includeSourceCode` | `any` | No | Include pass source code in subshader data. Requires 'includeSubshaders' to be true. Can produce very large responses. Default: false | ### Input JSON Schema ```json { "type": "object", "properties": { "assetRef": { "$ref": "#/$defs/com.IvanMurzak.Unity.MCP.Runtime.Data.AssetObjectRef" }, "includeMessages": { "$ref": "#/$defs/System.Boolean" }, "includeProperties": { "$ref": "#/$defs/System.Boolean" }, "includeSubshaders": { "$ref": "#/$defs/System.Boolean" }, "includeSourceCode": { "$ref": "#/$defs/System.Boolean" } }, "$defs": { "System.Type": { "type": "string" }, "com.IvanMurzak.Unity.MCP.Runtime.Data.AssetObjectRef": { "type": "object", "properties": { "instanceID": { "type": "integer", "description": "instanceID of the UnityEngine.Object.
