FulfillmentInbound_listInboundPlanItems

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

No annotations are provided, so the description carries the behavioral burden. It does disclose that the operation is a paginated list and that it runs in a different deployment, which is useful context. However, it does not describe the return shape, pagination mechanism, or any read-only guarantees.

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 mostly front-loaded, with the key functional statement near the end. The opening 'Catalog entry' is slightly redundant, but overall it wastes little space.

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 tool with no output schema and no annotations, the description is too thin. It does not explain what item packages are, how pagination works, what the returned items look like, or what prerequisites exist, so an agent cannot confidently invoke it.

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 exposes no properties and allows additional properties, but the description gives no parameter names or invocation details. Since the tool lists items 'in an inbound plan,' an agent still needs to know how to identify that plan, and the description does not compensate for the empty schema.

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 clear verb and resource: it provides a paginated list of item packages in an inbound plan. This is enough to distinguish it from create/update operations, though it does not explicitly differentiate it from sibling list tools like listInboundPlanBoxes or listShipmentItems.

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?

There is no guidance on when to use this tool versus the many similar FulfillmentInbound list tools. The note that it runs in the Kuudo deployment and not here is an environment constraint, not usage guidance.

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