s3_update_traffic_info

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

Annotations already mark the call as not read-only and not destructive. The description adds one useful behavioral fact beyond annotations: the operation is restricted to administrators. It does not explain side effects, what 'updating traffic info' changes, or expected outcomes, so transparency is only partial.

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 clear sentence with the action front-loaded. It loses slight credit because the parenthetical endpoint '(s3/update_traffic_info)' merely repeats the tool name and adds no information.

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 simple 2-parameter, no-output-schema tool the description is minimally adequate: it names the action and admin requirement. However, it does not state what the operation does concretely or what a successful call returns, leaving some ambiguity for an agent deciding whether to invoke it.

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 schema already documents both confirm and account_id. The description itself adds no parameter detail; per the baseline rule, a 3 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 uses a specific verb and resource: 'Обновить информацию о трафике S3-аккаунта' (update S3 account traffic info), which names the operation and its target. It is distinct enough from the many S3 sibling tools (s3_get_users, s3_delete_account, etc.), though it does not explicitly contrast with any sibling.

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 only usage guidance is the authorization constraint 'Доступно только администраторам' (admins only), and the schema hint points to s3_get_users for resolving account_id. No explicit when-to-use/when-not-to-use or alternative tool is given, so the usage context is mostly implied.

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