apple_list_win_back_offers

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

No annotations are provided, so the description must carry full behavioral disclosure. 'List' implies a read-only operation, but the description does not mention permissions, pagination behavior, filtering by status, or any return-shape expectations. The behavioral profile is therefore only minimally inferable.

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 wasted language. The parenthetical clarification earns its place by defining win-back offers.

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 simple one-parameter read-only listing tool, the description covers the subject and scope sufficiently for selection. However, with no annotations and no output schema, it leaves pagination and return behavior unaddressed, so it is not fully complete.

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% and the sole parameter is documented as 'Subscription ID'. The description reinforces that the subscription is the listing scope but adds no format or syntax details beyond the schema, so the baseline score 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?

The description uses a specific verb and resource: list win-back offers. It also states the scope, configured for a subscription, and clarifies the business meaning with churned/expired subscribers. This makes it clearly distinct from the sibling apple_get_win_back_offer retrieval tool.

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 scope 'for a subscription' and the parenthetical explanation imply when the tool is useful. However, it does not explicitly distinguish when to use this list operation versus apple_get_win_back_offer or the offer-code tools, and it provides no exclusions or prerequisites.

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