s3_cancel_account_deletion

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

Annotations indicate a non-read-only, non-destructive operation, and the description adds a meaningful behavioral outcome: canceling the deletion process and restoring the active account status. It lacks edge-case details such as behavior for already-deleted accounts, but with annotations present the additional context is reasonably sufficient.

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, focused sentence that front-loads the action and outcome. The parenthetical endpoint reference is a useful implementation detail and does not add unnecessary length.

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 two-parameter mutation with full schema coverage and no output schema, the description plus schema provide all essential context: what operation is performed, when it applies, and what the expected result is. No critical guidance is missing.

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 fully documents both parameters: confirm (must be true) and account_id (with guidance to check via s3_get_users). The description itself adds no new parameter-level meaning, so the 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?

The description uses a specific action ('Отменить' / cancel) and clearly identifies the resource: the S3 deletion process initiated through billing, with the explicit outcome of restoring the account's active status. This clearly differentiates it from mutating siblings like s3_delete_account or s3_delete_payment_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 description specifies the condition 'инициированный через биллинг' (initiated through billing), giving the agent a clear context for when to use this tool. It does not explicitly name alternatives or state when not to use it, so it falls 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.
