Batch Update One Time Products

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

With no annotations, the description carries the behavioral disclosure burden. It does disclose a meaningful restriction ('Disabled in read-only mode'), signaling this is a write operation with environment constraints. However, it does not mention partial-failure behavior, atomicity, permissions, or effects beyond 'update', leaving significant behavioral gaps.

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?

Two short sentences, with the core action front-loaded and the read-only mode restriction placed right after. Every sentence earns its place without redundant wording.

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?

For a two-parameter tool with fully described parameters and an output schema, the description is mostly complete. It clearly identifies the operation and the read-only restriction, though it could add a note about when to use patch_one_time_product instead or about batch failure semantics. Still, nothing essential is missing for invoking the 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 description coverage is 100%, so the schema already documents package_name and requests, including the UpdateOneTimeProductRequest structure with oneTimeProduct, updateMask, and optional regionsVersion/allowMissing. The description adds no parameter-level detail beyond what the schema provides, so the baseline of 3 is appropriate.

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 a specific verb ('Update'), resource ('one-time products'), and scope ('multiple ... in a single operation'), which clearly distinguishes it from single-product tools like patch_one_time_product and from batch_get/batch_delete variants. The title reinforces the same meaning.

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 phrase 'in a single operation' implies the tool is for updating multiple items at once, but the description does not explicitly say when to prefer it over alternatives such as patch_one_time_product for single updates or batch_update_purchase_option_offers for other resource types. Usage context is implied rather than spelled out.

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