Skill (Tool) / Create

How to Call

unity-mcp-cli run-system-tool unity-skill-create --input '{
  "path": "string_value",
  "code": "string_value"
}'

For complex input (multi-line strings, code), save the JSON to a file and use:

unity-mcp-cli run-system-tool unity-skill-create --input-file args.json

Or pipe via stdin (recommended):

unity-mcp-cli run-system-tool unity-skill-create --input-file - <<'EOF'
{"param": "value"}
EOF

Troubleshooting

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
`path`	`string`	Yes	Path for the C# (.cs) file to be created. Sample: "Assets/Skills/MySkill.cs".
CRITICAL — Assembly Definition placement: If the project uses Assembly Definition files (.asmdef), you MUST place the script inside a folder that belongs to an assembly definition which already references all required dependencies (e.g. com.IvanMurzak.McpPlugin, UnityEditor, UnityEngine). Placing the file in the wrong assembly will cause compile errors due to missing type references. Before choosing a path, inspect existing .asmdef files with the assets-find tool to identify the correct assembly folder.
`code`	`string`	Yes	C# code for the skill tool.
