gsheets_spreadsheets_values_get

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and openWorldHint=true, so the safety profile is covered structurally. The description adds nothing beyond that — no mention of behavior for missing/empty ranges, error cases, or whether the range must already exist — so it contributes essentially no behavioral context of its own.

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?

A single front-loaded sentence with zero padding. It is efficient, though arguably terse given the tool takes five parameters.

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?

Annotations cover the safety profile and the schema fully documents inputs, so the description's burden is lighter. Still, with no output schema, it says only that 'values' are returned without hinting at the row/column shape that majorDimension controls, which is the main thing an agent must reason about.

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% and the parameters (range, spreadsheetId, majorDimension, valueRenderOption, dateTimeRenderOption) are already richly documented in the schema, including an example for majorDimension. The description adds no parameter meaning at all, so the baseline 3 applies.

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?

States a specific verb and resource ('Returns a range of values from a spreadsheet'), which is clearly readable. However, it does not differentiate this from siblings such as gsheets_spreadsheets_values_update or gdocs_documents_get, leaving the agent to infer the read-vs-write distinction from the name alone.

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?

There is no when-to-use guidance, no mention of when NOT to use it, and no reference to the sibling update tool. The agent gets an implied read-only purpose from the verb but nothing explicit about context or alternatives.

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