excel_autofit_all_columns

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

With no annotations provided, the description carries full burden for behavioral disclosure. It states the action but fails to mention potential side effects (e.g., layout changes, data visibility impacts), permissions required, or error conditions. This leaves significant gaps for a mutation tool affecting workbook structure.

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, direct sentence with zero wasted words, clearly front-loading the core action and scope. It efficiently communicates the essential purpose without unnecessary elaboration, making it highly concise and well-structured.

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?

For a mutation tool with no annotations and no output schema, the description is insufficient. It lacks details on behavioral traits, error handling, or result format, leaving the agent with incomplete context to invoke the tool safely and effectively in complex scenarios.

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 input schema has 100% description coverage, detailing all three parameters with defaults and meanings. The description adds no parameter-specific information beyond implying column width adjustment, so it meets the baseline for high schema coverage without compensating further.

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 ('Auto-fit column widths') and scope ('for all worksheets in the workbook'), making the tool's purpose immediately understandable. However, it doesn't explicitly differentiate from the sibling tool 'excel_autofit_columns', which likely has a narrower scope, so it misses the highest score.

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 the sibling 'excel_autofit_columns' or other formatting tools. It lacks context about prerequisites, dependencies, or typical scenarios for application, offering minimal usage direction.

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