ExternalFulfillmentShipments_createPackages

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

With no annotations provided, the description carries the full behavioral burden. It does disclose a notable trait: the operation executes remotely in the Kuudo deployment rather than in the current environment. However, it does not mention side effects such as persistent package creation, required permissions, idempotency, or expected outcomes, leaving substantial behavioral ambiguity.

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 'Catalog entry.' is a wasted fragment that does not explain anything. 'Runs in your Kuudo deployment, not here' is behaviorally relevant but placed without context. The final clause is the only actionable part, so the structure is only partially effective.

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 creation-like operation with no annotations, an empty schema, and no output schema, this description is insufficiently complete. It leaves out how to identify the shipment, what package details are required, what the response looks like, and whether there are side effects. The only useful contextual addition is the remote-execution note.

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 schema declares zero properties and sets additionalProperties:true, so there are no parameter names or types to rely on. The description's 'Provide details about the packages in the specified shipment' gives a general hint that the input should include package information and a shipment reference, which adds slight value, but it still falls short of describing the actual free-form body needed.

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 never states that the tool creates packages; instead it says 'Provide details about the packages in the specified shipment,' which reads as input instructions rather than a description of the operation. 'Catalog entry' is ambiguous and adds no action-oriented clarity. It does not distinguish this tool from sibling tools like updatePackage or updatePackageStatus.

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?

No guidance is given on when to use this tool versus alternatives in the sibling list. The note that the operation 'runs in your Kuudo deployment, not here' is an operational caveat, not a usage guideline. There are no mentions of prerequisites, exclusions, or conditions that would help an agent choose this tool.

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