ebay_bulk_update_price_quantity

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

No annotations exist, so description carries full burden. It lacks disclosure on whether updates are additive or destructive, idempotency, error handling for partial failures, or required permissions and rate limits.

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 single sentence is concise, but it omits critical details needed for effective use, making it somewhat under-specified.

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 complexity of nested objects and no output schema, the description is too brief. It fails to explain required fields (offerId, price, currency, value), constraints, or result behavior.

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%, but description adds no extra meaning beyond the schema's structure. It does not explain complex nested fields like pricingSummary or the optional availableQuantity.

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 clearly states the verb 'update' and the resources 'price and quantity' for 'multiple offers'. It effectively distinguishes from sibling tools like 'ebay_update_offer' (single) and other bulk operations for different resources.

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 on when to use this tool versus alternatives such as 'ebay_update_offer' for single offers or 'ebay_bulk_create_offer' for creating offers. No context on prerequisites or constraints.

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