create_blank_file

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

No annotations are provided, so the description carries the full burden. It discloses the core behavior (creates a blank Excel file) but does not state whether the tool overwrites existing files, whether it creates parent directories, what happens if the file already exists, or what the output schema represents. For a creation tool with no annotation support, this is a notable gap.

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 sentence, front-loading the action and resource. It is concise and to the point, though it could add a bit more detail without becoming bloated.

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 tool is simple (one required parameter) and has an output schema, so the description is close to sufficient. However, the absence of any overwrite/conflict behavior or path details means an agent might make incorrect assumptions when calling it. It is adequate but not complete for a creation tool with no annotations.

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 description coverage is 0%, so the schema provides no meaning beyond the parameter name and type. The description adds that the parameter is a 'path' for the new file, which adds context. However, it does not specify path format (absolute vs relative), file extension handling, or whether the path should include .xlsx/.xls. Baseline is 3 due to low coverage, and the description does add some but not full value.

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 ('Create') and resource ('a new blank Excel file') and includes the key parameter ('at the given path'). It clearly distinguishes from siblings like list_sheets or set_cell_value, though it doesn't explicitly name an alternative.

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 a use case: creating a new blank Excel file. It doesn't specify when to use this tool versus add_sheet or add_data_to_sheet, nor does it mention any prerequisites (e.g., the file must not already exist, or parent directory requirements). No exclusion or alternative guidance is given.

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