list_purchase_option_offers

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

With no annotations provided, the description carries the transparency burden. It adequately conveys a non-mutating, read-only listing operation, but it does not disclose details such as return shape, pagination, active/inactive offer status, or potential wildcard performance implications. No annotation contradiction is present.

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, front-loaded sentence with no filler or repetition. It communicates the essential operation in minimal space.

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 simple input schema, presence of an output schema, and small number of parameters, the description is almost sufficient for an agent to select and invoke the tool. It could be more complete by mentioning offer state or pagination caveats, but these are minor gaps.

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 already covers 100% of the parameters with descriptions, so the baseline score of 3 applies. The description adds no extra semantic layer beyond referring to the parent 'one-time product purchase option,' but it does not need to because the schema is complete.

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 uses a specific verb ('List') and a precise resource ('offers for a one-time product purchase option'), clearly distinguishing this tool from the many sibling mutation, subscription, and product-management tools. It matches the tool name and the targeted entity accurately.

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 implies when to use the tool: when you need all offers for a one-time product purchase option. However, it does not explicitly mention alternatives such as batch_get_purchase_option_offers for targeted offer retrieval, nor does it say when not to use this tool, so usage guidance remains implicit rather than explicit.

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