FulfillmentOutbound_updateFulfillmentOrder

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

With no annotations provided, the description carries the behavioral burden. It discloses that the operation is a mutation, may both update and request shipment, and runs in the Kuudo deployment rather than locally. However, it does not mention permissions, side effects, reversibility, or what 'requests shipment' concretely triggers.

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 front-loads the core operation while adding a useful deployment caveat. 'Catalog entry' and 'Runs in your Kuudo deployment, not here' overlap slightly, so it is concise but not maximally tight.

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?

There are no annotations and no output schema, and this is a mutating operation. The description explains what the tool is for but not how the agent should invoke it, what payload fields are expected despite the empty schema, how the update/request-shipment choice is made, or what response/side effects to anticipate. It supports selection but not confident invocation.

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 properties, so the 0-param baseline applies; no parameter documentation is strictly needed. The description adds no parameter detail, but there are no declared parameters for it to explain. The additionalProperties:true allowance could be flagged, but it does not reduce the baseline.

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 ('Updates and/or requests shipment') and names the exact resource ('fulfillment order') with a distinguishing condition ('with an order hold on it'). This clearly separates it from the many FulfillmentOutbound sibling tools like create, cancel, or get.

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 implies when to use it: for a fulfillment order with an order hold. However, it does not explicitly state alternatives or when not to use it, such as using createFulfillmentOrder for non-held orders or cancelFulfillmentOrder to void. The usage context is present but left to inference.

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