FulfillmentInbound_cancelSelfShipAppointment

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

With no annotations, the description carries the disclosure burden, but it only states that the tool cancels a slot and runs in Kuudo. It does not disclose whether cancellation is reversible, what prerequisites exist, what happens to the shipment, or what response is returned, which is important for a cancel operation.

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 contains no filler, and the cancellation action is clear. However, the cryptic 'Catalog entry' and deployment note appear before the action, making the structure slightly less front-loaded than it could be.

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?

A cancel operation with no output schema, no annotations, and an empty schema needs more than a one-line action. The agent is left uncertain about how to identify the appointment or shipment and whether to invoke the tool at all, given the statement that it runs in the Kuudo deployment, not here.

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 the baseline for zero-parameter tools is 4. The phrase 'against a shipment' implies some identifying information may be needed, but with no declared parameters, there is little explicit parameter semantics to add.

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 states a specific verb and resource: 'Cancels a self-ship appointment slot against a shipment.' This clearly distinguishes the cancellation intent from sibling operations like scheduling or generating appointment slots. The 'Catalog entry' and Kuudo note add extra context but do 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?

No guidance is provided about when to use this tool versus alternatives such as scheduleSelfShipAppointment or generateSelfShipAppointmentSlots. The only contextual hint is that it runs in the Kuudo deployment, not here, which is an environment limitation rather than a clear usage rule.

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