ebay_get_compatibility_property_values

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

No annotations are provided, and the description fails to disclose any behavioral traits like auth requirements, read-only nature, error handling, or rate limits. The one-line description offers no insight beyond the tool name.

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 short sentence, which is concise but fails to convey necessary detail. It is not front-loaded with key information; it's merely a restatement of the tool name.

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 complex nested input schema, lack of output schema, and no annotations, the description is severely incomplete. An agent cannot understand what the tool returns, how to structure the request, or what prerequisites exist.

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 description coverage is 100% (the top-level 'data' parameter has a description), but the tool description adds no meaning to the complex nested parameters. The agent would need to infer how to populate 'specification' and its subfields without any guidance from the description.

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 states 'Get compatibility property values', which is vague. It does not specify that it retrieves possible values for a given compatibility property, nor does it differentiate from sibling tools like ebay_get_compatibility_property_names or ebay_get_compatibilities_by_specification.

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 vs. alternatives. The description lacks context such as prerequisites, typical use cases, or exclusions.

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