create_sheet

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

No annotations are provided, so the description must carry the full burden. It does not disclose failure modes (e.g., duplicate sheet name, invalid spreadsheet ID), authentication requirements, side effects, or rate limits. Minimal transparency beyond the basic action.

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, direct sentence with no fluff or repetition. It is front-loaded with the core purpose and ends with the API context. Every word earns its place.

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 lack of an output schema, the description does not mention return values (e.g., new sheet ID or metadata). It also omits error conditions and success indicators. For a creation tool, this is a notable gap, but the description covers the basic input context adequately.

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 parameters are well-documented structurally. However, the tool description adds no additional meaning, such as data type formats, valid value ranges, or interactions between parameters (e.g., 'initial_data' with 'sheet_properties').

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 verb 'Create' and the resource 'new sheet within an existing Google Spreadsheet'. It uniquely identifies the tool's function, distinguishing it from siblings like 'delete_sheet' or 'list_sheets'.

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 the tool adds a sheet to an existing spreadsheet but provides no explicit guidance on when to use it versus alternatives (e.g., 'create_spreadsheet' for new spreadsheets) or mention of prerequisites like the spreadsheet ID must exist.

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