ebay_create_notification_destination

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It merely states 'Create a notification destination' without revealing any behavioral traits such as whether the operation is idempotent, what happens on duplicate names, whether it requires prior configurations, or what the response contains.

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 (6 words) but lacks structure. It is front-loaded with the core action but omits important context. While brevity is valued, the description is too minimal to be fully useful, scoring at the middle of the range.

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 incomplete given the tool's complexity and lack of output schema. It does not explain what the output of the creation is (e.g., returns a destination ID), nor does it mention prerequisites, required scopes, or relationships to other notification tools. A more complete description would include these elements.

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 100% coverage with descriptions for all parameters. The description adds no additional meaning beyond what the schema provides. Baseline of 3 is appropriate since the schema already documents each parameter adequately.

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 'create' and the resource 'notification destination'. It distinguishes this tool from sibling tools that perform other operations on notification destinations (e.g., delete, update) or related notifications (e.g., subscription). However, it does not define what a notification destination is, which could be ambiguous for an agent unfamiliar with eBay's API.

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 provides no guidance on when to use this tool versus alternatives. For example, it does not mention that creating a destination is a prerequisite for creating a notification subscription, or any relationship with other tools like ebay_create_notification_subscription or ebay_update_notification_destination.

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