render_turntable

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

No annotations are provided, so the description carries the burden of behavioral disclosure. It usefully discloses that it returns one image path per view and instructs the agent to inspect all of them. However, it is silent about side effects, blocking behavior, output file management, or whether existing renders are overwritten.

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?

Three short sentences with no wasted words. The purpose is front-loaded, the rationale is useful, and the output instruction is placed last. Every sentence contributes to correct use.

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?

With six schema parameters, no annotations, and no output schema, the description is too thin to fully support correct invocation. It explains one use case and the output format, but leaves parameter semantics and tool selection guidance uncovered. An agent would still need to guess at several optional parameters' meanings.

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 very low (17%), with only 'views' described as 'Angles to render'. The description reinforces the views concept but does not explain 'label', 'objects', 'engine', or 'samples', several of which are not self-evident. With such low schema coverage, the description needed to compensate and did not.

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?

Uses a concrete verb ('Render') and a clear resource ('the same subject') with an explicit multi-angle scope ('several angles at once'). It also states the output shape ('one image path per view'), making the core function unmistakable. The emphasis on multiple views distinguishes it from the sibling render_preview without needing to name it.

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?

Gives a clear use case: catching problems that a single view would hide, with a concrete example ('a front view will not show that the back is hollow'). It does not explicitly name when to prefer render_preview over this tool, so it stops short of a full when-to-use/when-not-to-use statement.

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