Unity Component Skills
BATCH-FIRST: Use *_batch skills when operating on 2+ objects to reduce API calls from N to 1.Guardrails
Mode: Full-Auto required
DO NOT (common hallucinations):
component_create/component_getdo not exist → usecomponent_add(add) andcomponent_get_properties(read)component_finddoes not exist → usecomponent_listto list components on an objectcomponentTypeis case-sensitive —Rigidbodynotrigidbody,BoxCollidernotboxcollider- Custom scripts need exact class name; if namespaced, use
Namespace.ClassName
Routing:
- To create a C# component script → use
scriptmodule'sscript_createfirst, thencomponent_add - To set multiple properties at once → use
component_set_property_batch - To enable/disable a component →
component_set_enabled(notcomponent_set_property)
Object Targeting: All single-object skills acceptname(string),instanceId(int, preferred), andpath(string, hierarchy path). Provide at least one.
Skills Overview
| Single Object | Batch Version | Use Batch When |
|---|---|---|
component_add | component_add_batch | Adding to 2+ objects |
component_remove | component_remove_batch | Removing from 2+ objects |
component_set_property | component_set_property_batch | Setting on 2+ objects |
Other Skills (no batch):
component_list- List all components on an objectcomponent_get_properties- Get component property valuescomponent_set_enabled- Enable/disable a component (Behaviour, Renderer, Collider)component_copy- Copy a component from one object to another

import unity_skills
# BAD: 6 API calls
unity_skills.call_skill("component_add", name="Box1", componentType="Rigidbody")
unity_skills.call_skill("component_add", name="Box2", componentType="Rigidbody")
unity_skills.call_skill("component_add", name="Box3", componentType="Rigidbody")

unity_skills.call_skill("component_set_property", name="Box3", componentType="Rigidbody", propertyName="mass", value=2.0)
# GOOD: 2 API calls
unity_skills.call_skill("component_add_batch", items=[
{"name": "Box1", "componentType": "Rigidbody"},
{"name": "Box2", "componentType": "Rigidbody"},
{"name": "Box3", "componentType": "Rigidbody"}
])
unity_skills.call_skill("component_set_property_batch", items=[
{"name": "Box1", "componentType": "Rigidbody", "propertyName": "mass", "value": 2.0},
{"name": "Box2", "componentType": "Rigidbody", "propertyName": "mass", "value": 2.0},
{"name": "Box3", "componentType": "Rigidbody", "propertyName": "mass", "value": 2.0}
])Best Practices
- Add colliders before Rigidbody for physics
- Use
component_listto verify additions - Check property names with
component_get_propertiesfirst - Some properties are read-only (will fail to set)
- Use full type names for custom scripts (e.g., "MyNamespace.MyScript")
Additional Skills

targetPath | string | No* | null | Target hierarchy path |
componentType | string | Yes | - | Component type to copy |

Returns: {success, source, target, componentType}
component_set_enabled
Enable or disable a component (Behaviour, Renderer, Collider, etc.).
| Parameter | Type | Required | Default | Description |
|---|---|---|---|---|
name | string | No* | null | GameObject name |
instanceId | int | No* | 0 | Instance ID |
