The instructions your model reads when the skill loads.
Open prefab edit mode for a specific GameObject. In the Edit mode you can modify the prefab. The modification will be applied to all instances of the prefab across the project. Note: Please use 'assets-prefab-close' tool later to exit prefab editing mode.
gameObjectRef — reference to a scene prefab instance OR a prefab asset GameObject. The tool resolves the prefab asset path via PrefabUtility.GetPrefabAssetPathOfNearestInstanceRoot and opens the appropriate prefab stage.Asset-side GameObjects open via the simple OpenPrefab(path) overload. Scene-instance GameObjects open via OpenPrefab(path, gameObject) so the editor remembers which instance prompted the edit. Editor windows are repainted before returning. Throws when the GameObject cannot be resolved or the stage fails to open.
unity-mcp-cli run-tool assets-prefab-open --input '{
"gameObjectRef": "string_value"
}'
For complex input (multi-line strings, code), save the JSON to a file and use:
unity-mcp-cli run-tool assets-prefab-open --input-file args.jsonOr pipe via stdin (recommended):
unity-mcp-cli run-tool assets-prefab-open --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.
