FulfillmentInbound_listPrepDetails

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

No annotations are provided, so the description must carry the behavioral burden. It does add useful context: the tool runs in the Kuudo deployment, not locally, and MSKUs with certain characters need encoding. However, it does not disclose authentication requirements, side effects, or return behavior; 'Get' implies read-only but that is left implicit.

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 brief and mostly to the point, with no redundant elaboration. The opening 'Catalog entry.' is cryptic and not clearly necessary, but the rest of the description is efficiently structured.

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?

With an empty schema, no output schema, no annotations, and a large sibling toolset, the description is materially incomplete. It tells the agent what the tool does conceptually but not how to construct a valid request or interpret the response. The deployment note and encoding caveat are helpful but fill only a small portion of the gap.

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 an empty object with additionalProperties allowed, so there are no documented parameter names. The description adds core semantics by mentioning a list of MSKUs and a specified marketplace, plus the encoding note, but it never tells the agent how to pass those values or what parameter names to use. This is useful but not fully actionable.

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 the operation: 'Get preparation details for a list of MSKUs in a specified marketplace.' This is a specific verb and resource combination. It does not explicitly differentiate from sibling tools like setPrepDetails or getPrepInstructions, so it misses the top score.

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 when-to-use guidance or comparison to alternatives. The phrase 'Runs in your Kuudo deployment, not here' is an environment caveat rather than usage direction. An agent receives no help choosing this over FulfillmentInboundV0_getPrepInstructions or FulfillmentInbound_setPrepDetails.

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