Unity Component Skills

> BATCH-FIRST: Use *_batch skills when operating on 2+ objects to reduce API calls from N to 1.

Operating Mode

• Approval：本模块 Mixed —— component_list / component_get_properties 标 SkillMode.SemiAuto，可直接执行；写类 skill (component_add / component_set_property / component_set_enabled / component_copy 等) 标 SkillMode.FullAuto，需 grant 单次执行返结果。
• Auto / Bypass：FullAuto 直接执行。
• 含 NeverInSemi 高危 skill：component_remove / component_remove_batch（Operation.Delete）。这些在 Approval/Auto 下返 MODE_FORBIDDEN，仅 Bypass 或 Allowlist 命中可调。

DO NOT (common hallucinations):

• component_create / component_get do not exist → use component_add (add) and component_get_properties (read)
• component_find does not exist → use component_list to list components on an object
• componentType is case-sensitive — Rigidbody not rigidbody, BoxCollider not boxcollider
• Custom scripts need exact class name; if namespaced, use Namespace.ClassName

Routing:

• To create a C# component script → use script module's script_create first, then component_add
• To set multiple properties at once → use component_set_property_batch
• To enable/disable a component → component_set_enabled (not component_set_property)

> Object Targeting: All single-object skills accept name (string), instanceId (int, preferred), and path (string, hierarchy path). Provide at least one.

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="Box1", componentType="Rigidbody", propertyName="mass", value=2.0)
unity_skills.call_skill("component_set_property", name="Box2", componentType="Rigidbody", propertyName="mass", value=2.0)
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

1. Add colliders before Rigidbody for physics
2. Use component_list to verify additions
3. Check property names with component_get_properties first
4. Some properties are read-only (will fail to set)
5. Use full type names for custom scripts (e.g., "MyNamespace.MyScript")
