Unity Smart Skills

Guardrails

Mode: Full-Auto required

DO NOT (common hallucinations):

• smart_create / smart_build do not exist → smart skills are query/layout tools, not creation tools
• smart_search / smart_query do not exist → use smart_scene_query (component property filters) or smart_scene_query_spatial (spatial region filters)
• smart_move does not exist → use smart_snap_to_grid or smart_align_to_ground

Routing:

• For creating objects → use gameobject module
• For simple object search → use gameobject_find or scene_find_objects
• For complex scene queries (SQL-like) → smart_scene_query (this module)

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.

| Parameter | Type | Required | Default | Description | |-----------|------|----------|---------|-------------| | layoutType | string | No | "Linear" | Linear, Grid, Circle, Arc | | axis | 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

---

smart_reference_bind

Auto-fill a List/Array field with matching objects.

| Parameter | Type | Required | Default | Description | |-----------|------|----------|---------|-------------| | targetName | string | Yes | - | Target GameObject | | componentName | string | Yes | - | Component on target | | 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

Find objects within a sphere/box region, optionally filtered by component.

| Parameter | Type | Required | Default | Description | |-----------|------|----------|---------|-------------| | x | float | Yes | - | Center X coordinate | | y | float | Yes | - | Center Y coordinate | | z | float | Yes | - | Center Z coordinate | | radius | float | No | 10 | Search sphere radius | | componentFilter | string | No | null | Only include objects with this component | | limit | int | No | 50 | Max results |

Returns: { success, count, center, radius, results }

---

smart_align_to_ground

Raycast selected objects downward to align them to the ground. Requires objects selected in Hierarchy first.

| Parameter | Type | Required | Default | Description | |-----------|------|----------|---------|-------------| | maxDistance | float | No | 100 | Maximum raycast distance | | alignRotation | bool | No | false | Align rotation to surface normal |

Returns: { success, aligned, total }

---

smart_distribute

Evenly distribute selected objects between first and last positions. Requires at least 3 objects selected in Hierarchy first.

| Parameter | Type | Required | Default | Description | |-----------|------|----------|---------|-------------| | axis | string | No | "X" | X, Y, Z, -X, -Y, -Z |

Returns: { success, distributed, axis }

---

smart_snap_to_grid

Snap selected objects to a grid.

| Parameter | Type | Required | Default | Description | |-----------|------|----------|---------|-------------| | gridSize | float | No | 1 | Grid cell size |

Returns: { success, snapped, gridSize }

---

smart_randomize_transform

Randomize position/rotation/scale of selected objects within ranges.

| Parameter | Type | Required | Default | Description | |-----------|------|----------|---------|-------------| | posRange | float | No | 0 | Position randomization range | | rotRange | float | No | 0 | Rotation randomization range (degrees) | | scaleMin | float | No | 1 | Minimum uniform scale | | scaleMax | float | No | 1 | Maximum uniform scale |

Returns: { success, randomized }

---

smart_replace_objects

Replace selected objects with a prefab (preserving transforms). Requires objects selected in Hierarchy first.

| Parameter | Type | Required | Default | Description | |-----------|------|----------|---------|-------------| | prefabPath | string | Yes | - | Asset path to the replacement prefab |

Returns: { success, replaced, prefab }

---

| Parameter | Type | Required | Default | Description | |-----------|------|----------|---------|-------------| | componentName | string | Yes | - | Component type name to search for |

Returns: { success, selected, component }
