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

With no annotations provided, the description carries full burden for behavioral disclosure. It states this is a read operation but doesn't mention authentication requirements (beyond the user_google_email parameter), rate limits, error conditions, or what happens with invalid ranges. The return type is mentioned but without format details.

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 efficiently structured with a clear opening sentence followed by organized sections for Args and Returns. Every sentence adds value, and there's no redundant information. The formatting makes it easy to scan and understand.

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 moderate complexity (3 parameters, read operation) and the presence of an output schema (though not shown here), the description covers the basics adequately. However, with no annotations and incomplete behavioral context, it leaves gaps about authentication flow, error handling, and practical usage scenarios.

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 description adds significant value beyond the schema, which has 0% description coverage. It explains what each parameter represents (e.g., 'range_name' examples like 'Sheet1!A1:D10'), clarifies defaults, and distinguishes required vs. optional parameters. This compensates well for the schema's lack of descriptions.

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 ('Reads values') and resource ('from a specific range in a Google Sheet'), making the purpose immediately understandable. However, it doesn't explicitly differentiate from sibling tools like 'get_spreadsheet_info' or 'modify_sheet_values', which would be needed for a perfect score.

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 no guidance on when to use this tool versus alternatives like 'get_spreadsheet_info' or 'list_spreadsheets'. It mentions required parameters but offers no context about prerequisites, permissions, or typical use cases.

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