sheets_batch_update

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

No annotations are provided, so the description must disclose behavioral traits. It only states 'Write' and provides a data example, but does not mention whether existing values are overwritten, whether the operation is atomic, required permissions, or any side effects. This is insufficient for a mutation tool.

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 two sentences with no fluff. The first sentence states the core action, and the second shows a data example. Highly concise and front-loaded.

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 simplicity (2 params, no nested objects), the description provides the essential information. However, it lacks details on edge cases like range validation, overwrite behavior, or response consequences. With an output schema available, this might be adequate, but it's still minimally complete.

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 schema has no descriptions for the two parameters. The description compensates by giving a concrete example of the 'data' array structure: [{'range': 'A1', 'values': [[...]]}], which clarifies the expected format. The spreadsheet_id parameter is self-explanatory. This adds meaningful value beyond the schema.

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 'Write' and the resource 'multiple ranges in one request', which distinguishes it from sibling tools like sheets_write that likely handle single-range writes. The data format example further clarifies the scope.

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 implies the tool is for batch writing to multiple ranges, but does not explicitly state when to prefer this over alternatives like sheets_write, nor does it mention any exclusions. Usage context is clear but underdeveloped.

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