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
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
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 }

---

smart_select_by_component

Select all objects that have a specific component.

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

Returns: { success, selected, component }
