Uranian TNPs

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

Annotations already declare readOnlyHint=true, destructiveHint=false, idempotentHint=true. The description adds no behavioral context beyond stating the resource. It does not describe what the tool computes or how it uses inputs, so it adds no value over the annotations.

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 very short but poorly structured. The group label is helpful, but the example is vague and mismatched with the schema. The description is under-specified rather than concise.

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 11 parameters, no output schema, and no parameter explanations, the description is grossly incomplete. An agent cannot determine what data to provide or what the tool returns, making it unsuitable for use.

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 0%. The description does not explain any of the 11 parameters, even required ones like date and time. The example request body is incomplete and includes a 'chart' field not present in the schema, which is confusing. This leaves the agent without essential guidance for providing valid inputs.

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 '8 Hamburg trans-Neptunian bodies', specifying the resource but lacking an explicit verb like 'get' or 'list'. The title 'Uranian TNPs' provides context, but the purpose is only implied. It distinguishes from siblings by mentioning 'Hamburg' and 'trans-Neptunian', but the lack of an action reduces clarity.

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 provided on when to use this tool versus alternatives. There are many sibling cosmobiology tools, but the description does not compare or contrast them. The agent is left without context for selection.

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