batch_get_subscription_offers

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It makes clear this is a read operation for multiple offers, but doesn't disclose batch size limits, partial-failure behavior, authentication requirements, or whether the operation is atomic. The presence of an output schema mitigates the need to describe return values, but batch-specific behaviors remain undisclosed.

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?

A single concise sentence that directly states what the tool does. Every word carries meaning and there is zero filler or redundancy. The structure is front-loaded with the verb and resource.

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 batch read operation with an output schema and a self-explanatory name, the description is mostly adequate. However, it would benefit from noting important operational details like the maximum number of requests allowed per call or behavior when one offer in the batch is invalid. The description is sufficient for a simple read but lacks edge-case context.

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% — all four parameters have descriptions in the input schema (e.g., 'Parent subscription product ID', 'List of GetSubscriptionOfferRequest bodies'). With high schema coverage, the baseline is 3, and the description doesn't need to compensate for missing parameter context. The schema itself notes the '-' wildcard for base_plan_id, which is valuable contextual info.

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 ('Get details') and clearly identifies the resource ('multiple subscription offers') with batch semantics ('in a single operation'). This effectively conveys the tool's purpose and distinguishes it from the singular get_subscription_offer. However, it doesn't explicitly contrast with list_subscription_offers, which might serve a similar lookup purpose.

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?

'In a single operation' implies a batching use case, suggesting this tool is for fetching multiple offers efficiently. However, the description never explicitly states when to prefer this over alternatives like calling get_subscription_offer in a loop or using list_subscription_offers, nor does it mention any request limits or constraints on batching.

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