excel_create

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

With no annotations and no behavioral disclosure, the description fails to inform about side effects, file location, naming conventions, or whether the spreadsheet is saved or opened. A creation tool should at least hint at the outcome (e.g., 'creates a new file in the default location').

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 extremely concise: a single sentence with no wasted words. However, it is underspecified, which trades off against completeness, but for conciseness alone it scores well.

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 no parameters and no output schema, the description is too minimal. It does not explain what the tool returns (e.g., a success message, file path, or opens the app), nor does it provide any context about the creation process. A more complete description would include result or 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?

There are no parameters, so the schema coverage is 100% by default. The description adds no parameter information, but baseline is appropriately set to 4 since the schema is empty and nothing is needed.

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 ('Create') and resource ('new Excel spreadsheet'), making the purpose unambiguous. However, it does not distinguish itself from sibling creation tools like 'create_note' or 'create_reminder', which also create new files or items, but the context of 'Excel' makes it specific enough.

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 usage guidance is provided. The description does not indicate when to use this tool versus alternatives (e.g., 'excel_write_cell' for editing existing sheets), nor does it mention any prerequisites or conditions for use.

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