Статус переноса S3-хранилища

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

The description presents the operation as a read-only status query, but annotations declare readOnlyHint=false, contradicting the implied read-only nature. This is a significant inconsistency that confuses the agent about whether the tool may have side effects. Flagged as annotation contradiction.

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, information-dense sentence that front-loads the main action and includes a useful list of returned attributes plus usage advice. It could be slightly more structured (e.g., separating usage from return values) but is efficient overall.

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 simple tool (1 param, no output schema), the description covers the purpose, return content, and usage context. It could add details about polling behavior or error conditions, but the provided information is largely sufficient for an agent.

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 schema already documents bucket_id with 100% coverage, including a required-field note. The description adds no additional parameter-specific meaning beyond establishing that this is the bucket being transferred, so a baseline score of 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?

Description explicitly states 'Возвращает статус переноса хранилища' (Returns transfer status) and specifies the resource (S3 bucket from third-party provider to Timeweb Cloud). Lists specific statuses and metrics, clearly distinguishing it from sibling tools like transfer_bucket (initiates transfer) and get_bucket (general bucket info).

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 phrase 'Используй после transfer_bucket' provides explicit temporal guidance for when to call this tool. However, it does not mention when not to use it or suggest alternative tools for other scenarios, so it falls short of a full 5.

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