get_coupon_status

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

No annotations are provided, so the description carries the full burden. It discloses only that the call is read-only and is a SOAP operation; it says nothing about required permissions, error behavior when the coupon code is invalid/absent, or what the status response contains.

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?

Three short fragments, front-loaded, but 'GetCouponStatus' is repeated twice in adjacent sentences, making them partly redundant. Efficient if not informative.

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?

With no annotations, no output schema, and an undocumented parameter, the description is far too thin: an agent cannot tell what a returned coupon status looks like or how to call this 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 description coverage is 0% and the single parameter sCouponCode is documented nowhere. The description does not clarify what the coupon code is, its format, or that it is effectively needed despite being optional, so it adds no meaning beyond the schema.

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 largely restates the tool name: 'Calls GetCouponStatus on the Meser10 platform' plus 'SOAP operation: GetCouponStatus.' The only added value is naming the Meser10 platform. It does not say what a coupon status is or what the operation returns, so it is close to tautology.

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?

No guidance on when to use this tool versus the many sibling get_* / list_* tools. 'Read-only' implies a safe lookup, but there is no indication of context, prerequisites, or alternatives.

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