Ship Shipment Orders

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

Annotations already specify readOnlyHint=false, destructiveHint=false, and idempotentHint=true, so the safety profile is known. The description adds the outcome 'completes fulfillment' but does not disclose potential side effects like inventory changes, reversibility, or prerequisites (e.g., order must be in a certain state). This is adequate but not rich.

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 compact and well-structured: a one-sentence purpose, a brief Args list, and a one-line Returns note. No redundant information, and the most important content (the action) is front-loaded. Every sentence provides value.

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 one-parameter mutation with annotations covering idempotency and safety, the description gives the core information: action, parameter, and return value. It could improve by mentioning prerequisites or irreversible consequences, but given the simplicity and existing annotations, it is largely complete. However, the Returns line is vague ('the ship operation result from Logiwa') without a schema, and no usage guidance is included.

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?

Schema coverage is 100% and the schema already describes the parameter fully: 'Shipment order UUIDs to mark as shipped (required, >=1).' The description restates the parameter in the Args section as 'one or more order UUIDs to ship,' which adds minimal clarification (e.g., that they are UUIDs) but doesn't materially exceed the schema's own description. Baseline of 3 applies.

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 tool's action: 'Mark one or more shipment orders as shipped (completes fulfillment).' The verb 'mark as shipped' directly identifies the operation on shipment orders, and the parenthetical 'completes fulfillment' provides additional domain context. This clearly distinguishes it from sibling tools like cancel, create, or update.

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 provides clear context that this tool is for shipping orders and completing fulfillment, which implies its usage. However, it does not explicitly mention when not to use it or point to alternatives among the sibling tools, such as cancel_shipment_order or update_shipment_order. Thus it meets the 'clear context, no exclusions' level rather than the top tier.

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