"description": "AI-powered scene operations — SQL-like and spatial object queries plus automatic layout and auto-binding. Use when querying scene objects by condition or proximity, auto-arranging objects, or auto-wiring references, even if the user just says \"找出所有…的物体\" or \"自动排列\". AI 驱动的场景操作(类 SQL 与空间对象查询、自动布局、自动绑定);当用户要按条件或邻近关系查询场景对象、自动排布对象、或自动连线引用时使用。"

Operating Mode
- Approval：本模块 Mixed —— 只读查询 skill
smart_scene_query/smart_scene_query_spatial（标ReadOnly = true,Mode = SkillMode.SemiAuto）可直接执行；其余布局/绑定/变换类 skill (smart_scene_layout/smart_reference_bind/smart_align_to_ground/smart_distribute/smart_snap_to_grid/smart_randomize_transform/smart_select_by_component) 为SkillMode.FullAuto，需用户 grant 单次执行返结果。 - Auto / Bypass：直接执行。
- 含 NeverInSemi 高危 skill：
smart_replace_objects（Operation.Modify|Delete，会替换并删除原对象）。该 skill 在 Approval/Auto 下返MODE_FORBIDDEN，仅 Bypass 或 Allowlist 命中可调。

Skills
smart_scene_query
Find objects based on component property values (SQL-like).
| Parameter | Type | Required | Default | Description |
|---|---|---|---|---|
componentName |
string | Yes | - | Component type (Light, Camera, MeshRenderer) |
propertyName |
string | Yes | - | Property to query (intensity, enabled, etc.) |
op |
string | No | "==" | ==, !=, >, <, >=, <=, contains |
value |
string | No | null | Value to compare |
limit |
int | No | 50 | Max results |
query |
string | No | null | Unsupported shorthand; if provided alone returns a guidance error |
Example:
# Find all lights with intensity > 2
call_skill("smart_scene_query", componentName="Light", propertyName="intensity", op=">", value="2")
smart_scene_layout
Organize selected objects into a layout.

string | No | "X" | X, Y, Z, -X, -Y, -Z |
spacing |
float | No | 2.0 | Space between items (or radius) |
columns |
int | No | 3 | For Grid layout |
arcAngle |
float | No | 180 | For Arc layout (degrees) |
lookAtCenter |
bool | No | false | Rotate to face center |
Example:
# Arrange selected objects in a circle
call_skill("smart_scene_layout", layoutType="Circle", spacing=5)
smart_reference_bind
Auto-fill a List/Array field with matching objects.
| Parameter | Type | Required | Default | Description |
|---|---|---|---|---|
targetName |
string | Yes | - | Target GameObject |

fieldName |
string | Yes | - | Field to fill |
sourceTag |
string | No | null | Find by tag |
sourceName |
string | No | null | Find by name contains |
appendMode |
bool | No | false | Append instead of replace |
Example:
# Fill GameManager.spawns with all SpawnPoint tagged objects
call_skill("smart_reference_bind", targetName="GameManager", componentName="GameController", fieldName="spawns", sourceTag="SpawnPoint")
smart_scene_query_spatial
