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

With no annotations, the description must disclose behavioral traits. It states that it places an order and returns a confirmation with a snapshot of the cart, which is useful. However, it does not mention that checkout is likely irreversible, may trigger payment, or that the cart will be emptied—important details for a mutating action like this.

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 that clearly states the action and outcome. It contains no filler or redundant information, making it highly concise and well-structured.

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 tool is a checkout action that has significant side effects (financial transaction, cart clearing), yet the description only mentions placing an order and returning confirmation. It lacks prerequisites like having items in the cart or having payment details configured. An output schema exists for return values, but the behavioral context is still incomplete for such a complex action.

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?

The tool has zero parameters, so the baseline is 4. The input schema is empty, and no parameter descriptions are needed. The description adds no parameter semantics, but no such semantics are required for a parameterless tool.

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 'Оформляет заказ' (places/checks out order) with a clear resource 'текущей корзине' (current cart). It distinctly performs a final purchase action, differentiating it from sibling tools like view_cart and add_to_cart which manage the cart rather than complete it.

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 implies usage when the user has a current cart ready to check out, and returns a confirmation. However, it does not explicitly state when to use this tool over alternatives, such as mentioning it should be used after adding items to the cart or that it should not be used for merely viewing cart contents.

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