SetMerchantOrderInfoList

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

With no annotations, the description should disclose behavioral traits. It only says 'send a batch of operations' without explaining idempotency, error handling, auth requirements, or side effects. Minimal transparency.

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?

Single sentence with key information: deprecation, purpose, and limit. No fluff, though it could benefit from a brief note on alternative (v3).

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?

Missing details: what 'merchant information' comprises, how to specify operations, and what the response looks like. No output schema, so description should cover return values.

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 (100% coverage by default), but the description implies the tool accepts a batch of operations (max 100). This adds meaning beyond the empty schema, but fails to describe the structure or format of those operations.

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 is deprecated, its purpose (batch set merchant info on orders), and a key constraint (max 100 items). It effectively distinguishes from sibling tools like SetMerchantOrderInfo (single) and v3 variants.

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 (e.g., SetMerchantOrderInfoListV3). Only a batch limit is mentioned, but no context about prerequisites, order states, or exclusions.

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