create_folder

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

With no annotations provided, the description carries the full burden of behavioral disclosure, yet it offers nothing beyond a one-line Italian phrase. It doesn't explain what happens when a folder with the same name exists, where folders are created (e.g., in mail? drive?), authentication requirements, or side effects. This is a significant gap for a tool that likely has side effects (creating a resource).

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 'Crea una nuova cartella.' which is concise, but this is under-specification rather than effective conciseness. It's not well-structured for an English-speaking agent; the tool name is in English while the description is in Italian, which could cause confusion.

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 there's no output schema, no annotations, and minimal schema, the description needed to provide context about return values, side effects, and prerequisites. It does none of this. The sibling tools suggest this is part of an email system (send_mail, list_folders) but without context, it's very incomplete.

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%, and the description adds no parameter meaning. The schema shows `name` (string, required) and `account_id` (integer or null, default null), but nothing explains what `account_id` is, why it's needed, or what format `name` should take. The description doesn't compensate for the lack of schema documentation.

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 'Crea una nuova cartella' (Create a new folder) uses a verb and resource but is extremely minimal. It doesn't specify what kind of folders, where, or clarify what 'folder' means in this context. It doesn't distinguish itself from the sibling tool `delete_folder` or other folder-related tools beyond the obvious.

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 vs. alternatives. The sibling tools include `create_event`, `send_mail`, etc., but no exclusions or context is provided. The description fails to mention scenarios where this tool should or shouldn't be used, making it hard for an agent to know when this is the right choice.

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