Clone Entity

clone_entity

Duplicate a Cinema 4D entity (object, tag, material, shader, render data, video post, or take), specifying optional parent placement, and return a handle to the new copy.

Instructions

Duplicate an entity. Supports object / tag / material / shader (via GetClone + parent insert), render_data (doc.InsertRenderData — copies VideoPosts too), video_post (rd.InsertVideoPost), and take (TakeData.AddTake, copying existing overrides). Objects default to dropping next to the source; pass parent to place the clone elsewhere. Returns a handle to the new entity.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
nameNoOptional name for the clone.
handleYesSource entity to clone.
parentNoFor objects: destination parent (defaults to source's sibling). For tags: required owner object. For shaders: required owner. For video_post: target render_data (defaults to source's host). For take: parent take as handle (defaults to source's parent).

TDQS

A4.5/5.0
Behavior4/5

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

With no annotations, the description carries the behavioral burden and reveals meaningful traits: API-specific behavior per type (GetClone, InsertRenderData, AddTake), copying of VideoPosts/overrides, parent defaulting, and return of a handle. It doesn't discuss side effects like whether child objects are duplicated, but it goes well beyond a bare 'duplicate entity'.

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?

Every sentence adds information: operation, supported types, type-specific mechanics, default placement, and return value. It is dense but front-loaded and free of filler.

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

Completeness5/5

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

For a complex multi-type tool with no output schema, it covers all entity kinds, parent behavior, defaults, and return type. Nothing essential is missing for an agent to invoke it correctly.

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?

Schema coverage is 100%, so the baseline is 3, but the description adds meaningful default behavior for parent and clarifies destination semantics per entity type. It also confirms the return handle, which complements the handle parameter.

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 opens with 'Duplicate an entity', a specific verb and resource, then enumerates the supported entity types (object/tag/material/shader/render_data/video_post/take). This cleanly differentiates it from creation tools like create_entity and from query tools like list_entities.

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

Usage Guidelines4/5

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

It states the operation clearly and gives type-specific context, such as 'Objects default to dropping next to the source; pass `parent` to place the clone elsewhere', so an agent can infer when to call it. It does not explicitly name alternatives or exclusion conditions, but the sibling set makes the use case evident.

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