get_sketchfab_status

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only says 'Return availability status,' which is almost identical to the tool name and does not explain what 'status' entails (e.g., connectivity, service health, error handling). It also doesn't state that this is a read-only network check or any potential side effects. The description adds little beyond the name.

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 no wasted words. For a zero-parameter status check, this length is appropriate and front-loaded with the core action.

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 presence of an output schema covers return values, so the description doesn't need to explain them. However, given the lack of annotations and minimal prose, it might be helpful to mention that this checks network connectivity to Sketchfab or that it is a lightweight read-only call. Still, for a trivial tool, the description is functionally complete enough.

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 tool has zero parameters, so the baseline is 4. The description correctly implies there are no parameters to explain. Since the schema is empty and coverage is 100%, there is nothing more to add.

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 ('Return') and resource ('availability status for Sketchfab'), which is clear. However, it does not differentiate from sibling tools like get_polyhaven_status, which follow the same pattern. It is not a tautology but lacks distinguishing context.

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 on when to use this tool versus alternatives such as get_polyhaven_status or get_geometry_nodes_status. There is no mention of preconditions, exclusions, or specific scenarios. The agent is left to infer that it is for checking Sketchfab availability without any comparative context.

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