sheets_format_cells

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

No annotations are provided, and the description does not disclose behavioral traits such as whether formatting overwrites existing formats, permission requirements, or side effects. The description is too brief to offer meaningful transparency beyond the basic operation.

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 sentence that gets straight to the point. It could be slightly more detailed without becoming verbose, but it is efficient and front-loaded with key information.

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 lack of annotations and output schema, the description is insufficient for an agent to fully understand the tool's effects and return behavior. It does not explain how the tool interacts with existing formatting, what the response contains, or any constraints like range limits.

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 0%, so parameters 'range', 'format', and 'spreadsheetId' lack any explanatory text. The description hints at format contents ('colors, fonts, alignment, number formats') but does not clarify the structure or expected values, leaving the agent to infer meaning solely from parameter names.

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 cells') and the resource ('in a Google Sheet'), with specific formatting categories listed in parentheses. While it lacks explicit distinction from sibling tools like sheets_batch_format_cells, the purpose is directly communicated.

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 provided on when to use this tool versus alternatives such as sheets_batch_format_cells or sheets_update_values. The description does not indicate prerequisites, limitations, or comparative context.

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