C2.9/5.0
Behavior3/5

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

Annotations already declare readOnlyHint=false, destructiveHint=false, and openWorldHint=true, so the safety profile is covered. The description adds only that the workbook is created empty and placed in a folder; it says nothing about permission requirements, name collisions, or side effects on the target folder. With annotations carrying the main burden, this is modest added value.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single efficient sentence with the key constraint ('empty') and location front-loaded. It is not padded, though the extreme brevity is arguably under-specification rather than optimal conciseness.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists so return values need not be described, but for a 3-parameter mutation tool with 0% schema coverage and no usage or behavioral detail, the description leaves too much unstated for an agent to call it confidently.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0% and no parameter is explained in the description. 'in a folder' weakly implies folder_id, but the required 'name' and the optional 'description' parameter are entirely undocumented, leaving the description unable to compensate for the schema gap.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

Specific verb (Create) + resource (workbook) with a scope qualifier ('empty', 'in a folder'), so an agent knows it produces a blank workbook rather than a copy. It does not, however, distinguish itself from siblings like workbooks_create_workbook_from_template or workbooks_duplicate_workbook.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description offers no when-to-use context, no prerequisites (e.g., folder must exist, name uniqueness), and no routing guidance among the many sibling creation tools. The agent must infer that this is the tool for a blank workbook versus template-based or duplicated ones.

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