read_sheet

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

With no annotations present, the description bears the full burden of behavioral disclosure. It only states 'Read data from a Google Sheet', which is a basic functional description. It does not mention safety, idempotency, rate limits, error behavior, or any other behavioral traits. For a read operation, minimal disclosure is acceptable, but it still falls short of providing useful behavioral context.

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, concise sentence that front-loads the purpose. It is efficient with no wasted words. However, it is somewhat minimal and could benefit from including sibling differentiation or a hint about the output format without losing conciseness.

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 simplicity of the tool (one parameter, no output schema), the description adequately explains what the tool does but lacks completeness in describing the output. It does not mention what the returned data looks like (e.g., an array of rows/values), which is important since there is no output schema. The description also omits any usage context like typical use cases or prerequisites.

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 a single 'range' parameter that has a clear description and example ('Sheet1!A1:B10'). The tool description does not add any additional parameter information beyond what the schema provides. Baseline 3 is appropriate since the schema already does its job.

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 verb 'Read' and the resource 'Google Sheet', effectively conveying the tool's purpose. It distinguishes from sibling tools 'append_row' and 'update_cell' which are write operations. However, it could be more precise by explicitly mentioning that it reads from a specified range, as indicated by the required 'range' parameter.

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 explicit guidance is provided on when to use this tool versus alternatives. While the name and description imply it's for reading, and siblings handle writing, the description lacks direct statements of when/when-not to use it, nor does it mention exclusions or prerequisites. The agent must infer usage from context.

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