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

With no annotations provided, the description carries full burden but offers minimal behavioral insight. It doesn't mention whether this is a read-only operation, if it requires specific permissions, how it handles large datasets, or error conditions. The phrase 'Get data' implies reading, but no safety or performance details are disclosed.

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, efficient sentence that front-loads the core purpose. Every word earns its place, with no redundancy or unnecessary elaboration.

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?

For a simple read operation with full schema coverage but no output schema or annotations, the description is minimally adequate. It covers what the tool does but lacks details on behavior, alternatives, or output structure, leaving gaps for an AI agent to infer usage.

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 documented in the schema. The description adds no additional semantic context about parameters beyond implying data retrieval from a sheet. It doesn't explain defaults, constraints, or interactions between optional parameters.

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 ('Get data') and resource ('from a sheet in a standalone spreadsheet'), specifying the return format ('as a 2D array'). It distinguishes from siblings like spreadsheet.getCell or sheet.getDataPaginated by focusing on bulk data retrieval, though it doesn't explicitly name alternatives.

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?

No guidance is provided on when to use this tool versus alternatives like spreadsheet.getCell (for single cells), sheet.getDataPaginated (for paginated data), or sheet.getRows (for row-based access). The description lacks context about use cases or prerequisites.

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