Call C4D Command

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

With empty annotations, the description carries the full transparency burden, but it only references the underlying c4d.CallCommand() mechanism and lists example commands. It does not disclose side effects, blocking behavior, potential data loss (e.g., 'Make Editable'), undo implications, or error behavior — significant for an arbitrary-command passthrough.

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 efficient sentences with the verb+object front-loaded. The first sentence states what the tool does; the second narrows scope with useful examples. No wasted words.

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?

For a 3-parameter tool whose schema covers each parameter well, the surface is simple and mostly adequate. However, as a passthrough to arbitrary commands with no annotations or output schema, the description omits warnings about long-running or destructive commands (the schema hints at sync behavior in timeout_ms, not the description), leaving clear gaps for an agent deciding whether to call it.

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 schema already documents command_id, subid, and timeout_ms well, including ID examples, discovery via list_plugins, and a default timeout. The description adds marginal value by categorizing built-in commands, matching the baseline 3 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.

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

The description gives a specific verb+resource: 'Invoke a Cinema 4D command by plugin id via c4d.CallCommand()', with concrete examples of the commands it runs (render, save, make editable). It does not explicitly differentiate itself from siblings like modeling_command, render, or preview_render, so it misses the top mark, but the purpose is unambiguous.

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?

No guidance is given for when to pick this tool over the 77 siblings; 'Works for built-in commands ... and any registered command plugin' describes scope of supported commands rather than when to use this tool vs. alternatives like render or save_document. No exclusions, prerequisites, or 'use X instead' hints are provided.

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