excel_create

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

Annotations provide readOnlyHint=false and destructiveHint=false, but the description adds no behavioral context such as what happens to existing files at outputPath, whether the workbook is initialized in memory or written to disk, or that other operations depend on it. It does not contradict annotations but also adds zero value beyond them.

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 short phrase, but it is under-specified and repeats the tool name without adding informational value. True conciseness requires that each word earns its place; here the phrase provides no insight and is better classified as under-specification.

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 that the tool has 4 parameters, 2 required, no output schema, and multiple sibling tools for the same domain, this description is severely incomplete. It does not explain the tool's role in the Excel workflow, the significance of template/theme, the output path behavior, or any side effects.

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?

All four parameters have descriptions in the schema (100% coverage), so the baseline is 3. The tool description does not add any extra meaning to parameters such as title, outputPath, theme, or template beyond what the schema already provides.

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 '创建 Excel 工作簿' is essentially the Chinese translation of the tool name excel_create. It states a verb and resource but adds no detail that distinguishes this from sibling tools like excel_add_sheet or excel_save. It is a tautology rather than a meaningful purpose statement.

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?

There is no guidance on when to use this tool versus alternatives, no prerequisites, and no workflow positioning (e.g., 'create the workbook first, then add sheets'). The description completely lacks usage context.

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