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

No annotations are present, so the description bears full responsibility. It only states the basic operation without disclosing behavioral traits such as read-only nature, rate limits, error handling, or scalability for bulk requests.

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 sentence that effectively front-loads the purpose. Every word earns its place, though it sacrifices detail for brevity.

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 lack of output schema, nested parameter objects, and numerous siblings, the description is insufficiently complete. It does not explain return values, pagination, or behavior with invalid SKUs, leaving significant gaps for an agent to infer.

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%, providing a baseline of 3. The description 'Bulk inventory item get requests with SKU list' adds minimal context beyond the schema, confirming that the parameter is a list of SKUs but not explaining additional properties or constraints.

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 'Bulk get multiple inventory items' clearly states the action (get) and resource (inventory items), with 'Bulk' indicating multiple items. It distinguishes from single-get siblings but does not explicitly differentiate from related list 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?

No usage guidelines provided. The description does not specify when to use this tool versus alternatives like ebay_get_inventory_item or ebay_get_inventory_items, nor does it mention preconditions or limitations.

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