s3_create_order

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

The description adds a critical behavioral fact beyond the annotations: the operation creates a real order/invoice and involves real money ('ДЕНЬГИ'). This is exactly the kind of context that helps an agent avoid harmful calls, and it does not contradict the provided annotations.

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 short, purposeful sentences. The first states the action and billing link; the second delivers the financial warning in a prominent way. No wasted words, and the key warning is front-loaded enough to be noticed.

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?

Given the schema fully documents parameters and annotations indicate this is a mutating operation, the description adds the essential financial-impact context. Minor gaps remain: it does not describe the response/return value or point to sibling tools like s3_list_plans/s3_get_locations for valid plan_id/location values, but these are not required to invoke the tool 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?

The input schema already provides descriptions for all three parameters (confirm, plan_id, location), so schema coverage is 100%. The tool description adds no parameter-level details beyond the overall 'paid order' context, which matches the baseline score of 3 for high schema coverage.

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 ('Создать') and resource ('платный заказ на S3-хранилище'), and explicitly ties it to billing by mentioning 'привязка к биллингу' and 'создаёт реальный заказ/инвойс'. This clearly distinguishes it from sibling tools like s3_create_account and s3_create_bucket, and the endpoint is included for reference.

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 provides clear context: use this when creating a paid S3 order linked to billing, and the 'ДЕНЬГИ' warning implies careful use. It does not explicitly name alternatives or state when not to use it, so it stops short of full routing guidance.

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