ncloud_sens_get_alimtalk_reservation_status

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

The readOnlyHint annotation already signals a safe read operation, and the description adds the GET endpoint and the full set of possible statuses, which is useful since there is no output schema. It does not explain the semantics of statuses like STALE or SKIP, but it goes beyond what the annotation provides.

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 dense sentence that front-loads the action and resource, then adds the endpoint and status vocabulary. There is no filler or redundant restatement.

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 read-only status tool, the description plus the schema is sufficient: the required reserveId, optional serviceId discovery, and status values are all covered. It could be more complete by explaining status transitions or polling behavior, but nothing essential is missing for invoking it correctly.

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%, and both parameters have detailed schema descriptions, including the reserveId-to-requestId mapping and serviceId NRN/default/lookup guidance. The description itself adds no additional parameter detail, so it meets the baseline without exceeding it.

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 names a specific operation—getting the status of a scheduled AlimTalk reservation—and includes the exact endpoint and possible status values. This clearly distinguishes it from sibling tools like ncloud_sens_get_alimtalk_status and ncloud_sens_cancel_alimtalk_reservation.

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 clearly establishes the use case: checking the status of a scheduled AlimTalk request, which is distinct from listing, sending, or canceling reservations. It does not explicitly name alternatives or provide when-not-to-use exclusions, but the intended context is clear.

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