ebay_get_compatibility_property_names

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

With no annotations, the description carries the full burden but only repeats the tool name. It fails to disclose any behavioral traits such as read-only nature, prerequisites, rate limits, or return format.

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 only 4 words, which is concise but under-specified. It lacks crucial details such as what the output includes or the context of use, making it uninformative for an agent.

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 nested input schema and no output schema, the description is severely incomplete. It does not explain the purpose of the tool (e.g., automotive parts), expected output, or how to use the complex input structure.

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%, so baseline is 3. However, the parameter description 'Request data for getting compatibility property names' adds no meaningful explanation of the nested fields (categoryId, categoryTreeId, etc.) beyond what the schema provides.

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 compatibility property names' clearly states a verb and resource, but it lacks context about automotive parts or categories, and does not differentiate from similar siblings like 'ebay_get_compatibility_property_values'.

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 is provided on when to use this tool versus alternatives (e.g., get_compatibility_property_values, get_automotive_parts_compatibility_policies). The description offers no context or exclusions.

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