FulfillmentInbound_listDeliveryWindowOptions

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

With no annotations, the description carries the full burden of behavioral disclosure. It at least notes that execution happens in the Kuudo deployment rather than locally, but it does not clarify side effects, required authorization, failure modes, or whether options must exist before calling. The read-only nature is implied but not stated.

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, but the core action is placed last, after two short but somewhat confusing contextual sentences. 'Catalog entry' does little to help invocation and the deployment note, while potentially important, is not elaborated. It is not overly verbose, but it is not cleanly front-loaded.

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 annotations and no output schema, this description leaves too much unspecified: how the agent supplies the shipment, what the returned options look like, and how this step fits into the generate/list/confirm flow. The deployment caveat is an unusual detail but does not compensate for the missing operational context.

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 yet allows additionalProperties, so no parameter names or formats are documented. The description says 'for a shipment' but never tells the agent how to identify that shipment, which is a meaningful gap when the underlying tool likely requires a shipment identifier.

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 statement 'Retrieves all delivery window options for a shipment' gives a clear verb and object, which distinguishes this from the generate/confirm delivery-window siblings. The confusing 'Catalog entry' opening and 'Runs in your Kuudo deployment' clause soften the clarity, but the core purpose is still identifiable.

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 generateDeliveryWindowOptions or confirmDeliveryWindowOptions. It does not mention sequencing, prerequisites, or cases where an alternative should be chosen, leaving the agent to infer usage from the name alone.

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