read_sheet_data

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

With no annotations provided, the description minimally indicates the tool is read-only and uses the API directly. It lacks details on authentication, rate limits, pagination, or the effect of the value_render_option parameter, leaving behavioral traits underdisclosed.

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 very concise at one sentence, but it omits critical information like usage guidelines and parameter nuances. While efficient, it does not fully earn its place given the missing context.

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 presence of numerous sibling tools for reading and writing sheets, the description is incomplete. It does not explain return values, distinguish from get_sheet_data, or cover edge cases, leaving agents underinformed for selection and invocation.

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 coverage is 100% with descriptions for all three parameters, meeting the baseline. The tool description does not add any additional meaning beyond the schema, so no extra value is provided.

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 reads data directly via the Google Sheets API without requiring Apps Script, providing a specific verb and resource. However, it does not differentiate from sibling tools like get_sheet_data, which likely have overlapping functionality.

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 given on when to use this tool versus alternatives. The description implies it is for direct API reads but does not specify scenarios, prerequisites, or contrasts with siblings.

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