ebay_get_privileges

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

The description discloses that the tool is a read operation (Get) and specifies what is returned (registration status, selling limit). Since no annotations exist, it adequately covers the behavioral traits. However, it could explicitly state it is a safe, non-destructive call.

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 one concise paragraph, front-loaded with the main purpose, followed by specific details and OAuth scope. Every sentence adds value without redundancy.

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 tool has no parameters and no output schema, the description explains the key return components (registration status, selling limit). It is reasonably complete, though it could mention if the response includes additional fields or is paginated.

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 baseline 4. The description does not need to add parameter meaning, and it does not try to.

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 retrieves seller's privileges, including registration status and selling limit details. It uses a specific verb 'Get' and resource 'privileges', and the detail on selling limit distinguishes it from other generic get tools.

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 implies usage when seller privileges are needed but does not explicitly state when to use or not use this tool versus alternatives. No guidance on when to choose this over other get_* tools among the many siblings.

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