render_multiview

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

With no annotations, the description carries the full burden of behavioral disclosure. It does communicate the key output characteristic (a single grid image) and notes the default view set, which is useful. However, it does not mention potential side effects (if any), error behavior, output format details, or execution context such as whether the input code must be valid OpenSCAD.

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 concise sentence with the core idea front-loaded and a useful parenthetical clarifying the default view set. There is no wasted wording.

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 tool with five parameters, a nested object, no output schema, and no annotations, this description is too sparse. It does not explain how 'params' should be used, what the return output actually is beyond 'grid image', or how it relates to siblings. An agent would likely need additional inference to use all capabilities correctly.

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 description coverage is high (80%), and the description adds no detailed parameter semantics beyond what the schema already provides. It does reinforce that 'views' typically includes front, right, top, and perspective, but the 'params' nested object remains unexplained by both schema and description.

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 ('render') and a resource ('multiple views of the model in a single grid image'), and even enumerates the default views. This makes the tool's function clear and somewhat distinguishes it from siblings like 'render' and 'render_turntable', though it does not explicitly contrast them.

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?

There is no guidance about when to use this tool versus alternatives such as 'render' or 'render_turntable'. The name and description imply a grid of multiple views, but no exclusions or alternative routing are provided.

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