SetMerchantOrderInfoV3

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

With no annotations provided, the description must fully disclose behavioral traits. Only 'Set' is mentioned, implying a write operation, but there is no detail on whether it replaces or appends merchant info, prerequisites, error conditions, or side effects. This is insufficient for an agent to predict behavior.

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 with five words, extremely concise and front-loaded. Every word is necessary, and there is no redundancy. It earns a high score for efficiency.

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 no parameters and no output schema, the description should clarify how the merchant information is specified (e.g., via context or implicit data). It fails to explain what 'merchant information' entails or how the operation is carried out, leaving significant gaps for an agent.

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 no parameters require documentation. The description does not add parameter meaning, but the baseline is 4 for zero-parameter tools. No contradiction or missing information exists here.

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 action (Set) and the resource (Order's merchant information), indicating a mutation operation. However, it does not differentiate from sibling tools like SetMerchantOrderInfo or SetMerchantOrderInfoList, which likely serve similar purposes for single or multiple orders.

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 no guidance on when to use this tool versus alternatives such as SetMerchantOrderInfo, SetMerchantOrderInfoList, or ClearMerchantOrderInfoV3. An agent would need external knowledge to decide which tool to invoke.

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