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

With no annotations present, the description carries the full burden. It discloses key runtime behavior: for payment=acquiring a payment link is returned, and for payment=deposit the amount is debited from the merchant's deposit balance. This is significant side-effect and response context beyond the schema.

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?

Two tight sentences with zero filler. The first front-loads the core action and resource; the second efficiently explains the two payment-mode outcomes. Every part earns its place.

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?

The description plus schema cover invocation needs: required parameters, enums, and the meaning of payment modes. The lack of output schema is partially mitigated by mentioning the acquiring link, but the deposit-branch response shape is not disclosed; still, this is a minor gap given a sibling get tool for later retrieval.

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 description merely echoes the payment enum semantics already present in the schema. It adds no new parameter-level meaning for by or payload, so the baseline 3 for schema-covered parameters 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 opens with the specific verb «Создаёт» and names the precise resource: «заказ на пополнение Steam-аккаунта». This distinguishes it from sibling tools like wata_dg_stars_order_create and generic wata_dg_order_create without needing to inspect the schema.

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 use case is clear from the resource name, and the payment-mode sentence explains when each mode applies. However, the description does not explicitly state when to prefer this tool over alternative order-creation siblings or when not to use it, so guidance is implied rather than direct.

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