FulfillmentInbound_getShipmentContentUpdatePreview

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

With no annotations, the description must carry the behavioral burden, but it only partially does so. It discloses that the tool 'Runs in your Kuudo deployment, not here,' which is useful context, and 'Retrieve' implies a read-like operation. However, it does not state side effects, prerequisites, error behavior, or what 'can only be confirmed…' means, and the sentence is cut off.

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 but poorly structured: it opens with the filler phrase 'Catalog entry,' then an environment caveat, and only then the core purpose. The main sentence is incomplete, ending with an ellipsis. Every sentence should earn its place, and these do not.

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 retrieval tool, the description should clearly state what the returned preview contains, how it relates to the generate/list/confirm sibling operations, and what 'can only be confirmed' refers to. The description gives some return-content context but is truncated and lacks workflow or prerequisite information. Without an output schema or annotations, this leaves a significant gap for an agent deciding whether and how to invoke the tool.

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 documented parameters and 100% schema coverage, so the baseline for parameter semantics is 4. The description does not need to explain parameters that are not present, and it adds some context about what the tool returns. The 'additionalProperties: true' schema is ambiguous, but with zero required parameters this is not a major gap.

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 and resource: 'Retrieve a shipment content update preview' and indicates it summarizes shipment content changes plus transportation cost implications. This distinguishes it from sibling operations like list/generate/confirm previews, though the leading 'Catalog entry' and deployment caveat add noise. The truncated final clause prevents it from being fully clear.

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 gives no guidance on when to use this tool versus siblings such as FulfillmentInbound_generateShipmentContentUpdatePreviews, FulfillmentInbound_listShipmentContentUpdatePreviews, or FulfillmentInbound_confirmShipmentContentUpdatePreview. 'Runs in your Kuudo deployment, not here' hints at an environment constraint but does not explain the intended workflow or alternatives. The agent is left to infer sequencing from the operation name.

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