Can you create a directory called 'UI' inside the existing 'Assets/Prefabs' path in my project? I need the output to provide the folder GUID assigned upon completion.

The instructions your model reads when the skill loads.
Creates a new folder in the specified parent folder. The parent folder string must start with the 'Assets' folder, and all folders within the parent folder string must already exist. For example, when specifying 'Assets/ParentFolder1/ParentFolder2/', the new folder will be created in 'ParentFolder2' only if ParentFolder1 and ParentFolder2 already exist. Use it to organize scripts and assets in the project. Does AssetDatabase.Refresh() at the end. Returns the GUID of the newly created folder, if successful.
inputs — list of {ParentFolderPath, NewFolderName} entries. Each entry is processed independently; per-entry errors are collected in the response so a single bad input does not abort the batch.NewFolderName must be non-empty and must not contain any of /, \, <, >, :, ", |, ?, *, or control characters (these checks are cross-platform even on Linux/Mac).ParentFolderPath must already exist as an AssetDatabase.IsValidFolder path.unity-mcp-cli run-tool assets-create-folder --input '{
"inputs": "string_value"
}'
For complex input (multi-line strings, code), save the JSON to a file and use:
unity-mcp-cli run-tool assets-create-folder --input-file args.jsonOr pipe via stdin (recommended):
unity-mcp-cli run-tool assets-create-folder --input-file - <<'EOF' {"param": "value"} EOF
If unity-mcp-cli is not found, either install it globally (npm install -g unity-mcp-cli) or use npx unity-mcp-cli instead.
