FulfillmentInbound_updateShipmentName

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It indicates the operation updates a shipment name but does not mention side effects, permissions, reversibility, failure modes, or whether the tool is actually invocable in this environment. 'Catalog entry' and 'Runs in your Kuudo deployment, not here' hint at behavior but do not meaningfully disclose operational consequences.

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 easy to read, but it is not well front-loaded: the core action appears only in the final sentence. 'Catalog entry' adds little value and reads as filler, while 'Runs in your Kuudo deployment, not here' is context that could have been placed after the main purpose.

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 mutation tool with no annotations, no output schema, and an empty input schema, the description is too sparse to support reliable invocation. It does not state required identifiers, new name input, return behavior, or prerequisites. The description may help an agent select the tool, but not confidently invoke it correctly.

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 has zero parameters, so the baseline is 4. The description adds minimal parameter meaning by mentioning the updated field ('name') and target ('existing shipment'), but it does not specify how to identify the shipment or what input is expected. Since the schema itself provides no parameter information, the description could have done more, but the zero-parameter baseline applies.

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 clearly states a specific verb and resource: 'Updates the name of an existing shipment.' This distinguishes it from sibling update tools such as FulfillmentInbound_updateShipmentSourceAddress and FulfillmentInbound_updateShipmentTrackingDetails. The extra context about being a catalog entry and running in Kuudo does not obscure the core purpose.

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?

Usage is implied by the action: use this when an existing shipment's name needs to be changed. However, no alternatives are named and there is no explicit when-not-to-use guidance. The 'Runs in your Kuudo deployment, not here' note provides some environmental context but not a clear routing decision.

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