List MoGraph Clones

list_mograph_clones
Read-only

Reads per-clone transforms from MoGraph generators (Cloner, Matrix, Tracer). Forces a scene pass to populate MoData, then returns clone indices, positions, optional matrices, and a supported flag.

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.

  2. First observedv0.3.1

TDQS

A4.5/5.0
Behavior5/5

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

Annotations declare readOnlyHint=true, which the description aligns with by using 'Read'. Beyond that, the description discloses a forced scene pass to populate MoData, a meaningful side effect, and the exact return shape including the 'supported:false' condition. This adds substantial behavioral context that annotations do not cover, so it earns a 5.

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?

Two sentences with no fluff. The first sentence leads with the core action and supported inputs, the second covers return format and failure cases. Every sentence adds value, and the structure is front-loaded.

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 read-only tool with high schema coverage and no output schema, the description fully covers what an agent needs: what it does, the side effect of forcing a scene pass, the return structure, and when it returns supported:false. No missing information blocks correct invocation.

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 the schema already documents all three parameters (handle, max_count, include_matrix) with descriptions. The tool description adds no extra parameter-level meaning, but it does explain the overall data flow and return structure. Per the baseline rule for high coverage, a 3 is appropriate because the description does not need to repeat parameter semantics.

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 it reads per-clone transforms from a MoGraph generator, with specific verb 'Read' and resource 'per-clone transforms'. It also gives examples of generators (Cloner/Matrix/Tracer) and distinguishes itself from sibling tools like sample_transform that operate on individual objects, making its purpose unambiguous.

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?

The description implicitly communicates when to use this tool (to read clone transforms) and lists failure conditions (unsupported builds or non-MoGraph handles). It does not explicitly name alternatives or state when to prefer other tools, but the specialized resource makes the context clear. A small gap remains in not contrasting with siblings like sample_transform, so a 4 is warranted.

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