ebay_get_payment_policy

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

No annotations are provided, so the description bears full responsibility for behavioral disclosure. It only states 'Get a specific payment policy by ID' with no mention of read-only nature, authentication requirements, error handling, or what happens if the ID is invalid.

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 concise sentence with no unnecessary words. It directly communicates the purpose without extra details.

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 simple get-by-ID tool with one parameter and no output schema, the description is minimally complete. However, it lacks context on prerequisites (e.g., obtaining an ID from a list) and what the response contains, leaving some gaps.

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?

Schema coverage is 100%, with the parameter description already stating 'The payment policy ID'. The tool description adds no additional meaning, such as format or source of the ID, meeting the baseline for high schema coverage.

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 'Get a specific payment policy by ID' clearly states the verb (Get), resource (payment policy), and identifier (by ID). It effectively distinguishes from sibling tools like 'ebay_get_payment_policies' (plural) and 'ebay_get_payment_policy_by_name' (by name).

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 explicit guidance is provided on when to use this tool versus alternatives. It is implied that you use this when you have a known policy ID, while 'ebay_get_payment_policies' lists all and 'ebay_get_payment_policy_by_name' searches by name, but no such distinction is stated.

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