create_excel_workbook

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

There are no annotations, so the description carries the full burden of disclosing behavior. It states that a workbook is created, but does not disclose whether an existing file is overwritten, whether parent directories must exist, what permissions are required, or what side effects occur. This is a meaningful gap for a file-system mutation tool.

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 short, front-loaded with the main purpose, and the argument documentation is directly useful. There is no filler or redundant 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?

For a simple two-parameter creation tool, the description is mostly complete: it names the artifact type, the required path, and the optional sheet name. It lacks edge-case behavior like overwrite handling or return values, but the low complexity and single required parameter keep the gap relatively small.

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?

With 0% schema description coverage, the description does compensate by explaining that path is an absolute file path and sheet_name is the name of the first sheet. However, it adds only modest meaning beyond the schema's field titles and leaves constraints such as file-name validity or sheet-name rules unspecified.

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 states a specific verb and resource: create a new Excel workbook (.xlsx). This clearly distinguishes it from sibling tools like read_excel_workbook, write_excel_data, and create_word_document, so an agent can identify the tool's function at a glance.

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 the tool should be used when a new .xlsx workbook is needed, but it gives no explicit when-to-use or when-not-to-use guidance. It does not mention alternatives like write_excel_data or read_excel_workbook, so an agent must infer routing from the tool name and sibling list.

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