create_file

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

The description only states the basic action without disclosing behavioral traits such as file size limits, the fact that it stores the file URL in a variable (output_variable_name), or any side effects. Since no annotations are provided, the description carries full responsibility for transparency, and the minimal text fails to convey important behavioral context.

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 sentence with no wasted words. It is appropriately concise for a simple tool, though additional context (e.g., what happens after saving) could improve usefulness without sacrificing brevity.

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 the tool's simplicity (3 required params, no complex output), the description is largely complete: it identifies the action and result. However, it does not explain the role of 'output_variable_name' (storing the file URL) or mention that the file is downloadable, which is partially covered by the schema descriptions.

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 100%, so the baseline is 3. The description does not add any meaning beyond what the input schema already provides; it merely restates the core purpose without elaborating on how parameters like 'output_variable_name' function in the tool's operation.

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 uses a specific verb ('Save') and resource ('text content as a downloadable file'), clearly indicating the tool creates a file from text. This distinguishes it from siblings like 'convert_file' (which converts existing files) and 'format_text' (which does not produce a download).

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 explicit guidance on when to use this tool versus alternatives (e.g., 'convert_file' for converting existing files or 'get_variable_from_database' for retrieving stored data). The description implies usage for saving text as a file but does not provide exclusions or context for when other tools would be more appropriate.

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