ebay_get_inventory_location

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

With no annotations available, the description should disclose behavioral traits like authentication requirements or the nature of the read operation. It only states 'Get', which implies read-only but lacks explicit details, leaving significant gaps.

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 sentence with no fluff, but it lacks any additional structure or context that would improve readability. It is concise but could be expanded slightly without losing efficiency.

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 read operation with one parameter, the description provides the core purpose. However, it omits any mention of return values, prerequisites, or error conditions, which would be helpful given no output schema.

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 schema has 100% coverage, describing the one parameter 'merchantLocationKey' as 'The merchant location key'. The description adds no additional meaning, so it meets the baseline but does not enhance understanding.

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 inventory location' clearly states the verb 'Get' and the resource 'inventory location', with 'specific' distinguishing it from sibling tools like ebay_get_inventory_locations which retrieves multiple locations.

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 such as ebay_get_inventory_locations, or any prerequisites. The description is too minimal to aid in tool selection.

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