Unity Component Agent Skill

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.

Skills Overview

Best Practices

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