s3_create_order

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

The description goes beyond the annotations by clearly warning 'ДЕНЬГИ: создаёт реальный заказ/инвойс', disclosing a real financial side effect. This is exactly the behavioral context an agent needs before invoking a billing-affecting tool.

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 very short and front-loaded with the core purpose and the financial warning. There is no redundant or filler content.

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 low-complexity tool with fully documented parameters, the description is mostly complete. The main remaining gap is the absence of any return-value or post-condition information, but given the lack of an output schema and the clear billing warning, this is a minor gap rather than a blocking one.

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%, so the parameters are already fully documented. The description adds no additional meaning about plan_id, location, or confirm beyond what the schema provides, which is acceptable but not value-adding.

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?

Description states a specific verb and resource ('Создать платный заказ на S3-хранилище') and explicitly ties it to billing. The 'ДЕНЬГИ: создаёт реальный заказ/инвойс' warning further distinguishes it from non-billing S3 tools like s3_create_bucket and s3_create_account.

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 intended use is implied: this is the monetarily charged S3 order operation among the siblings. However, there is no explicit guidance about when to use it versus alternatives such as s3_list_plans or s3_create_bucket, nor any stated prerequisites like an existing billing account.

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