assets-prefab-open

# Assets / Prefab / Open 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. ## Inputs - `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. ## Behavior 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. ## How to Call ```bash 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: > ```bash > unity-mcp-cli run-tool assets-prefab-open --input-file args.json > ``` > > Or pipe via stdin (recommended): > ```bash > unity-mcp-cli run-tool assets-prefab-open --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.
