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

With no annotations, the description carries the burden of behavioral disclosure. It does disclose that the operation runs in the user's Kuudo deployment, not locally, and that it performs a purchase, implying a side effect. However, it does not detail financial implications, prerequisites, or what the returned documents contain.

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 short and front-loads key context: catalog entry, execution location, then the action and return value. The 'Catalog entry' phrase is slightly ambiguous, but overall the description is economical with no filler.

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 zero-parameter operation with no output schema, the description covers the essential action, execution context, and broad return type. It is incomplete in explaining what 'Catalog entry' means, whether prior rate selection is needed, and what specific purchase details or documents are returned.

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 defines zero parameters, and with 0 parameters the baseline is 4. The description does not add parameter-level detail, but none is required here. The schema's additionalProperties: true is not addressed, but it is not a practical concern given no documented parameters.

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 ('purchases') and a specific resource ('shipping service identifier'), and states that it returns purchase-related details and documents. This is clear, but it does not explicitly distinguish this from sibling tools like Shipping_purchaseShipment or Shipping_directPurchaseShipment.

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 provides no guidance on when to use this tool versus the many sibling shipping tools. It mentions that it runs in the Kuudo deployment rather than here, but this is environmental context rather than usage direction. No alternatives or exclusions are given.

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