SetMerchantOrderInfo

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

With no annotations and a vague description, there is no disclosure of behavioral traits such as idempotency, overwrite behavior, or error conditions.

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?

A single sentence that includes the deprecation note is as concise as possible, front-loading the most critical information.

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?

The description is severely inadequate for a deprecated tool with no parameters, no output schema, and no annotations; it fails to explain prerequisites, side effects, or how to use it at all.

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, which is confusing for a 'set' operation; the description does not explain how the tool knows which order or what merchant info, leaving significant ambiguity.

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 it sets merchant information on an order and includes a deprecation warning, but it does not differentiate this tool from its siblings like SetMerchantOrderInfoList 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 or when to use alternatives; the deprecated note suggests avoiding it but no explicit alternative is provided.

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