sheets_batch_format_cells

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

Annotations already provide idempotentHint: true and destructiveHint: false, covering the safety profile. The description adds the batching behavior but does not disclose additional traits like overwriting existing formatting or performance implications.

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 12-word sentence that front-loads the purpose without any filler or redundant information. Every word earns its place.

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 rich schema and annotations, the description is adequate for a straightforward batch formatting tool. However, it lacks guidance on constructing format objects and does not mention potential side effects like replacing existing formatting, leaving some gaps for complex use cases.

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%, with both parameters (spreadsheetId and formatRequests) already described. The description adds no extra meaning beyond the schema, so the baseline of 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?

The description clearly states the action (Format) and scope (multiple cell ranges in a Google Sheet), distinguishing it from the single-range sibling tool sheets_format_cells by emphasizing 'multiple' and 'in a single operation'.

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 batching ('multiple cell ranges', 'single operation') but does not explicitly state when to use this tool over alternatives like sheets_format_cells, nor does it provide any exclusions or prerequisites.

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