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

With no annotations, the description carries the burden of disclosing behavior. It explicitly states the action is permanent and cascades to all tabs, which are critical behavioral traits. It does not mention potential side effects (e.g., permissions or linked data), but the core irreversible nature is clearly conveyed.

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, front-loaded sentence of 13 words. Every word earns its place, conveying the verb, resource, and scope without redundancy.

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 tool's simplicity (1 param, no output schema), the description adequately covers the purpose and key behavior. While it does not detail return values or error responses, the absence of an output schema reduces the need for such detail, and the description is sufficient for a delete operation.

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 describes the single parameter 'id' as 'Sheet (workbook) ID' with 100% coverage. The description adds a small clarification by equating 'spreadsheet', 'excel', and 'workbook', but does not provide additional parameter syntax or format details, so the baseline 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 clearly states the action ('Permanently delete') and the resource ('a spreadsheet (sheet, excel, workbook)') with explicit scope ('and all its tabs'). This distinguishes it from sibling tools like delete_sheet_tab, which targets an individual tab.

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 implies usage for deleting entire workbooks, and the sibling tool delete_sheet_tab provides an obvious alternative for deleting only a tab. However, it does not explicitly state when to use this tool versus alternatives or mention any prerequisites.

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