ebay_get_multi_compatibility_property_values

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

With no annotations provided, the description carries full burden for behavioral disclosure. It only states 'Get multiple compatibility property values' with no mention of behavior such as whether it is read-only, required permissions, rate limits, or error handling. This is insufficient for an agent to anticipate tool behavior.

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 phrase front-loaded with the key action and resource. While it is efficient, it could include more useful information without becoming verbose.

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 complexity of the input (nested object with multiple subproperties) and absence of an output schema, the description is incomplete. It does not explain the return format, how results are structured, or how to interpret the response, leaving significant gaps for the agent.

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 the baseline is 3. The description adds no extra meaning beyond the schema's parameter descriptions. It does not clarify how to use the nested 'data' object or the relationship between 'propertyNames' and 'propertyFilters'.

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 multiple compatibility property values' clearly specifies the verb (Get) and resource (multiple compatibility property values). It distinguishes itself from siblings like ebay_get_compatibility_property_values (singular) and ebay_get_compatibility_property_names, making its purpose unambiguous.

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 on when to use this tool vs alternatives (e.g., instead of calling get_compatibility_property_values multiple times) is provided. The usage is only implied by the tool name, lacking explicit when/when-not or alternative references.

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