s3_create_account

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

Annotations already show this is a mutating call (readOnlyHint=false) and not destructive; the description adds that authorization is required and that the action binds a plan and bucket. It does not mention side effects such as billing/account creation implications or what happens after execution.

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?

A single sentence conveys the purpose, key binding details, and auth requirement with no filler. The essential information is front-loaded.

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 four-parameter tool whose schema documents every parameter, the description provides enough context about creating an S3 account. It could add a note on prerequisites/sources for plan_id and location, but those are already in the schema; no output schema exists, so return-value detail is not strictly required.

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 documented in the input schema. The description loosely maps plan_id and bucket to the 'tariff plan' and 'initial bucket' but adds no new semantic detail 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 uses a specific verb and resource — 'Создать S3-аккаунт' (create S3 account) — and clarifies it involves attaching a tariff plan and initial bucket. This distinguishes it from siblings like s3_create_bucket and s3_create_order.

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 usage is implied: it is the tool for creating an S3 account with a plan and initial bucket, and it notes authorization is required. It does not explicitly name alternatives, state when not to use it, or explain how it differs from s3_create_order/s3_create_bucket.

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