clone_object

Duplicate a 3D object to a new location in the scene by specifying source and target paths, with optional position offset.

Instructions

Duplicate an existing object to a new prim path.

Args: source_path: Prim path of the object to clone. target_path: Prim path for the cloned object. position: [x, y, z] position for the clone. Keeps original position if not set.

Input Schema

Behavior2/5

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

No annotations provided, so the description carries full burden. It does not disclose important behaviors like whether cloning is a deep copy, what happens if target_path exists, or error handling.

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 extremely concise: a single sentence stating the purpose, followed by a clearly structured parameter list with no fluff.

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

Completeness3/5

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

Covers basic input semantics well but lacks information about output (though output schema exists), error conditions, and side effects like overwriting behavior.

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

Parameters4/5

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

With 0% schema description coverage, the description adds clear, meaningful explanations for all three parameters, including an example for position.

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 clearly states the action (duplicate) and resource (existing object to a new prim path), distinguishing it from sibling tools like create_object and transform_object.

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

Usage Guidelines3/5

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

The description implies usage for copying objects but lacks explicit guidance on when to use versus alternatives or prerequisites.

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