Modeling Command

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

With no annotations, the description carries the full behavioral burden and does substantial work: it names the underlying API and discloses the key return distinction — new-geometry commands (Current State to Object, Connect/Join, Split, Explode Segments) return handles to inserted results, while in-place commands (Make Editable, Subdivide, Triangulate) return the mutated targets. It stops short of covering error conditions, destructiveness, or potential dialog behavior, but the return semantics are the critical unknown for an agent calling this tool.

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

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

Two information-dense sentences front-load the operation and return behavior before a functional alias list. There is no filler; the list length is inherent to supporting 16 command aliases.

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

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

The return-value disclosure partially compensates for the missing output schema and the highly nested targets schema. Gaps remain: no guidance on which aliases support which mode values, no error behavior for invalid command/target combinations, and no indication of whether operations are destructive or undoable — notable for a mutation tool with zero annotations.

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

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

Schema coverage is 100%, so the baseline is 3; the description is genuinely additive by expanding the command parameter into its full alias set and hinting at params usage with the 'subdivision level' example. This enriches what the schema's terse one-line descriptions provide.

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

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

The description states a specific verb and resource: 'Run a Cinema 4D modeling operation via c4d.utils.SendModelingCommand on one or more target objects.' It goes further than most by disclosing the return-behavior split between geometry-producing and in-place commands and enumerating 16 aliases, which clearly separates it from the generic call_command sibling.

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

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

The alias list and 'modeling operation' phrasing imply this is the tool for C4D modeling commands, but there is no explicit statement of when to use it over siblings like call_command, nor any exclusions, prerequisites, or target-type caveats. Usage context is implied rather than stated.

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