ChangeOrderV3

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

No annotations are provided. The description merely states 'change' without detailing side effects, requirements, or safety implications. It fails to disclose behavioral traits beyond the minimal description.

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 a single sentence, concise but potentially too sparse. It does not waste words but lacks sufficient detail for a proper understanding.

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?

Given the complexity of sibling tools and lack of output schema/annotations, the description is woefully incomplete. An agent cannot determine prerequisites, outcomes, or specific actions beyond the vague 'accept, ship, etc.'

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 parameters, so schema coverage is complete. However, the description does not explain why no parameters are needed or how the tool determines which order and what change to apply, leaving the agent without invocation guidance.

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 indicates the tool modifies marketplace order information and provides examples (accept, ship). However, it does not distinguish this V3 from sibling tools like ChangeOrder, ChangeOrderListV2, or SetMerchantOrderInfoV3.

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 on when to use this tool versus alternatives. Given many sibling tools for order changes, the agent lacks context for selection.

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