unity_gameobject_reparent

Move a Unity GameObject to a new parent in the hierarchy. Specify the object by path or instance ID, and choose the parent (empty for root). Optionally preserve world position.

Instructions

Move a GameObject under a new parent in the hierarchy.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
pathNoHierarchy path or name of the GameObject to move
instanceIdNoInstance ID (alternative to path)
newParentNoPath of the new parent (empty string for scene root)
worldPositionStaysNoMaintain world position after reparenting (default: true)
portNoTarget Unity instance port for parallel-safe routing. Get this from unity_select_instance. When working with multiple Unity instances, ALWAYS include this parameter.
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are present, so the description carries the full burden. It does not disclose side effects (e.g., impact on child GameObjects), reversibility (undo support), or failure conditions. The parameter descriptions in the schema cover details like worldPositionStays, but the description adds no behavioral context.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, front-loaded sentence with no wasted words. It is highly concise and immediately communicates the tool's purpose.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Despite having 5 parameters and no output schema or annotations, the description provides only a one-line summary. It omits high-level context such as required existence of the GameObject, the effect on transforms, or common use cases, leaving the agent underinformed.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so baseline is 3. The description adds no extra meaning beyond the schema's parameter descriptions (e.g., explaining the relationship between path and instanceId or that newParent can be empty for root).

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description 'Move a GameObject under a new parent in the hierarchy' clearly states the specific action (reparent) and the resource (GameObject), distinguishing it from sibling tools like unity_gameobject_delete or unity_gameobject_set_transform.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool versus alternatives such as unity_gameobject_set_transform for position changes or unity_gameobject_duplicate for duplication. No prerequisites or exclusions are mentioned.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
