ebay_bulk_get_inventory_item

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

No annotations are present, so the description must disclose behavioral traits. It only says 'Bulk get multiple inventory items' without mentioning idempotency, data returned, rate limits, or side effects. This is insufficient for safe invocation.

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, which is concise but too brief. It lacks important context without being overly verbose. It could be improved by adding a bit more substance while maintaining 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?

The tool is for bulk retrieval with a complex nested schema, but there is no output schema and no guidance on what the response contains (e.g., found items, errors, pagination). The description is incomplete for an agent to understand what to expect.

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 has 100% description coverage, with the schema already describing 'requests' as 'Bulk inventory item get requests with SKU list'. The description adds no additional meaning beyond what the schema provides, so it meets the baseline of 3.

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?

Description states 'Bulk get multiple inventory items' which is a clear verb+resource combination. It implies batch retrieval of inventory items by SKU, distinguishing from single-get (ebay_get_inventory_item) and possibly from list (ebay_get_inventory_items). However, it does not explicitly differentiate from siblings like ebay_bulk_create_or_replace_inventory_item.

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_item (single) or ebay_get_inventory_items (list). There are no prerequisites, limits, or exclusions mentioned. The description offers no context for appropriate usage.

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