Call C4D Command

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

With no annotations provided, the description carries the full burden of behavioral disclosure, but it only says 'Invoke' and names the API. It does not warn that many commands mutate the scene, may block the main thread, may open UI, or may have no meaningful return value. The synchronous behavior is only mentioned in the timeout parameter description, not in the tool description.

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?

The description is a single, front-loaded sentence that states the action, the target resource, the mechanism, and the scope of supported commands with useful examples. There is no wasted text.

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 description and schema together cover the command_id, subid, timeout, and discovery path, which is enough to make a basic call. However, because there are no annotations and no output schema, the description leaves the agent uncertain about side effects, return values, and failure modes for a potentially mutating call.

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?

The input schema fully documents command_id with examples and discovery guidance, plus subid and timeout_ms. The description adds little beyond saying 'by plugin id', so a baseline score of 3 is appropriate because the schema handles the semantic load.

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 uses a specific verb ('Invoke') and names the exact resource ('Cinema 4D command by plugin id') and mechanism ('via c4d.CallCommand()'). It clearly differentiates this generic command invoker from specialized siblings like render or save_document by emphasizing the plugin-id/CallCommand path.

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 description implies usage for built-in commands and registered command plugins, and gives examples like render, save, and make editable. However, it does not explicitly state when to prefer this tool over dedicated siblings such as render or save_document, nor does it state when not to use it.

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