List MoGraph Clones

list_mograph_clones
Read-only

Read per-clone transforms from Cinema 4D MoGraph generators such as Cloner, Matrix, or Tracer. Forces a scene pass so clone positions and matrices are populated before sampling.

Instructions

Read the per-clone transforms from a MoGraph generator (Cloner / Matrix / Tracer / …). The bridge forces a scene pass so the MoData array is populated before sampling. Returns {count, returned, clones: [{index, pos, matrix?}]}. supported:false when the build lacks c4d.modules.mograph or when the handle isn't a MoGraph generator.

  3. First observedv0.3.1

TDQS

A4.3/5.0
Behavior5/5

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

Annotations only give readOnlyHint=true; the description adds real behavioral context: the bridge forces a scene pass to populate the MoData array before sampling, and it discloses the supported:false failure conditions. This is exactly the kind of detail that goes beyond structured fields.

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?

Four tight sentences, each earning its place: purpose, internal mechanism, return shape, and failure mode. Front-loaded with the verb and resource.

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?

No output schema exists, so the description carries the return contract and does so explicitly ({count, returned, clones:[{index,pos,matrix?}]}). Combined with the supported:false semantics, an agent has everything needed to call and interpret it.

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 description coverage is 100%, so handle, max_count and include_matrix are already documented in the schema. The description adds only the 'matrix?' optionality of the return items, so the baseline 3 applies when the schema does the heavy lifting.

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?

States a specific verb (Read) and resource (per-clone transforms from a MoGraph generator), and names concrete generator types (Cloner / Matrix / Tracer). An agent can immediately distinguish this from mesh/transform siblings like get_mesh or sample_transform.

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?

Explains applicability to MoGraph generators and the failure case (supported:false when the build lacks c4d.modules.mograph or the handle isn't a generator), which is useful context. However, it never states when to prefer this over alternatives such as sample_transform, leaving the agent to infer the routing.

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