ebay_get_inventory_items

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

No annotations are provided, so the description carries full burden. It only mentions OAuth scopes, implying read-only behavior, but does not disclose rate limits, response format, side effects, or other traits beyond the scope statement.

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 concise with two sentences, first stating purpose and second providing scopes. It is front-loaded but lacks structure for guidelines or further details.

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 no annotations and no output schema, the description is incomplete. It fails to explain pagination behavior, response structure, or how to use parameters effectively, which is essential for a list tool.

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 coverage is 100% as both 'limit' and 'offset' parameters have descriptions in the input schema. The description adds no additional meaning beyond these schema descriptions, achieving baseline score.

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 'Retrieve all inventory items for the seller' with a clear verb and resource, indicating a list operation. It distinguishes from sibling 'ebay_get_inventory_item' by using 'all', but does not explicitly differentiate from 'ebay_bulk_get_inventory_item' or other bulk tools.

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 OAuth scope requirements but gives no guidance on when to use this tool versus alternatives like 'ebay_get_inventory_item' or 'ebay_bulk_get_inventory_item'. It does not mention pagination context or exclusions.

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