ebay_get_inventory_items

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

No annotations are provided, so the description must disclose behavioral traits. It mentions OAuth scopes (authentication requirement) but does not state that the tool is read-only, what happens during retrieval (e.g., pagination behavior), or any other side effects. The description lacks sufficient behavioral context.

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 highly concise, with two sentences that directly state the purpose and required OAuth scope. No unnecessary words, and the essential information is front-loaded.

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 that there is no output schema and no annotations, the description should provide more behavioral and contextual details (e.g., pagination, rate limits, response format). It only covers the OAuth requirement, leaving significant gaps for a retrieval tool in a large set of siblings.

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 input schema covers both parameters (limit, offset) with descriptions, achieving 100% coverage. The description does not add additional meaning beyond the schema, so it meets the baseline but does not exceed it.

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 clearly states the tool retrieves all inventory items for the seller, using a specific verb and resource. However, it does not distinguish from siblings like ebay_get_inventory_item (single item) or ebay_create_or_replace_inventory_item, which could be inferred from the name but lacks explicit differentiation.

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 the required OAuth scope as a prerequisite but does not indicate when to use this tool versus alternatives (e.g., ebay_get_inventory_item for a single item, or ebay_bulk_get_inventory_item for bulk retrieval). No exclusions or context for selection are given.

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