set_dimension_size

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

The description explains the zero-based, half-open index notation and the dimension parameter options (COLUMNS/ROWS), adding behavioral detail beyond the tool name. However, it does not disclose side effects, required permissions, or error conditions. With no annotations, more transparency would be beneficial.

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, using two sentences with a clear note format for parameter details. No redundant information is present.

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?

The core action is explained, but the description lacks usage guidelines and full parameter coverage. Given 6 required parameters and no output schema, it is adequate but not fully 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?

Schema coverage is 0%, so the description must explain parameters. It clarifies dimension and start/end indices but omits explanations for spreadsheet_id, sheet, and pixel_size, which are only partially inferable. This leaves significant gaps.

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 explicitly states the verb "Set" and the resource "fixed pixel size for a band of columns or rows," making the tool's purpose very clear. It distinguishes from siblings like auto_resize_dimensions which automatically sizes dimensions.

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 provides no guidance on when to use this tool versus alternatives such as auto_resize_dimensions or freeze. It only explains the parameters, not the context of use.

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