FulfillmentInboundV0_getLabels

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

With no annotations, the description must carry behavioral disclosure. It does reveal that execution happens in the Kuudo deployment rather than locally and that the operation returns labels, implying read-only behavior. But it does not state side effects, required permissions, output format, or error behavior, leaving important behavioral gaps for an unannotated tool.

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 the deployment context is front-loaded before the functional summary. It is slightly disjointed—'Catalog entry.' is a fragment and 'not here' is ambiguous—but it wastes little space and remains quickly scannable.

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 tool, the description gives the essential output ('package/pallet labels') and the execution environment. It is incomplete about what the output looks like, whether the tool is callable from the current server at all, and what prerequisites apply; no output schema or annotations exist to fill those gaps.

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 is empty with no required parameters, so there are no parameter semantics to explain. The description adds no parameter detail, but the zero-parameter baseline is 4, and nothing here violates that.

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 names a specific result—package/pallet labels for Amazon fulfillment center processing—so an agent can identify the tool's primary function. It does not explicitly distinguish this from sibling label/document tools (e.g., FulfillmentInboundV0_getBillOfLading, Awd_getInboundShipmentLabels), so it misses the top score. The 'Catalog entry... not here' phrasing adds deployment context but slightly muddles whether this tool actually returns labels in the current environment.

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 phrase 'for faster and more accurate shipment processing at the Amazon fulfillment center' provides a use context, and 'Runs in your Kuudo deployment, not here' states an exclusion. However, it never tells the agent when to prefer this over the many sibling label/shipping tools, nor what to use instead, so the guidance is only implied rather than explicit.

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