Use component_add with the target GameObject identified by name, instanceId, or hierarchy path, plus the componentType such as Rigidbody or BoxCollider. For multiple objects, component_add_batch performs all additions in one call.

Use component_set_property with the componentType, propertyName, and value. Values support primitives, vectors as x/y/z objects, colors as r/g/b/a, enums as strings, and scene or asset references via referencePath or assetPath.

Yes, component_copy duplicates a component between a source and target GameObject. component_copy_exact additionally verifies that serialized Inspector fields match and reports any mismatches.

The componentType parameter is case-sensitive, so Rigidbody works but rigidbody does not. Custom scripts require the exact class name, and namespaced scripts need the full form like Namespace.ClassName.

Use component_get_serialized_properties to list Inspector SerializedProperty paths, then component_set_serialized_property with the propertyPath, for example items.Array.data[0], to write the value.

Use batch skills whenever operating on two or more objects. component_add_batch, component_remove_batch, and component_set_property_batch reduce N API calls to one, which is significantly more efficient for scene-wide changes.
