ChangeOrder

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

The description only mentions that the tool changes order information, without specifying any side effects, permissions, or behavioral constraints. Given the lack of annotations, the description should provide more context for safe usage.

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 extremely concise: a single sentence with a clear deprecation flag upfront. No superfluous words, and the structure efficiently communicates the essential 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?

For a deprecated tool with zero parameters and no output schema, the description is minimally adequate. However, it lacks a pointer to the replacement tool, which would improve completeness without much extra text.

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 the baseline is 4. The description implies that some input (like which order and what change) is needed, but since no parameters are defined, the description is consistent and adds no semantic conflict.

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 verb 'Change' and the resource 'your marketplace Order Information', with examples such as accept and ship. This effectively conveys the tool's purpose despite the deprecation notice.

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 deprecation marker serves as a guideline to avoid using this tool, but it fails to explicitly recommend an alternative like 'ChangeOrderV3' or 'ChangeOrderListV3'. The guidance is partial.

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