create_spreadsheet

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

No annotations are provided, so the description must stand alone. It clearly states that the tool creates a new spreadsheet and returns the id and URL. This is sufficient for a creation tool, though it could mention irreversible nature or permissions.

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 two sentences: the first states the core function and return value, the second explains the optional parameter. It is concise, front-loaded, and contains no unnecessary words.

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?

The tool has 2 parameters (both explained), no output schema but return values are described (id and URL). For a simple creation tool, this is complete enough. It doesn't mention error handling, but that's acceptable for basic tools.

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 0%, so the description adds value by explaining the 'title' parameter as the spreadsheet title and 'sheet_titles' as optional seed for multiple named sheets. It provides enough meaning beyond the raw schema.

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 tool's purpose: 'Create a new spreadsheet and return its id and URL.' It uses a specific verb ('create') and resource ('spreadsheet'), and distinguishes it from sibling tools which are all about modifying existing spreadsheets.

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 provides guidance on using the optional parameter 'sheet_titles' to seed multiple sheets. While it doesn't explicitly state when to avoid this tool, there are no sibling tools for creating spreadsheets, so the context is clear enough.

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