create_email_folder

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

The description only states the action without disclosing behavioral traits like authentication requirements, idempotency, error conditions (e.g., if folder already exists), or side effects. Since no annotations are provided, the description should cover these aspects but fails to do so.

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, concise sentence that immediately conveys the tool's action. It is front-loaded with the key information and contains no unnecessary words or filler.

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 tool with no parameters and no output schema, the description should at least explain the scope (e.g., 'in the default mailbox') or confirm that a folder is created interactively. The current text is too sparse to fully inform an AI agent about the tool's behavior and limitations.

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?

The input schema has zero parameters, and schema description coverage is 100% (vacuously). The baseline for zero parameters is 4, but the description does not explain how the folder is created without specifying a name or location, leaving ambiguity. A score of 3 reflects that while the schema is fully covered, the description adds no clarity beyond the action.

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 verb 'Create' and the resource 'email folder/mailbox', making the tool's purpose understandable. It is distinct from sibling tools like 'move_email' or 'list_emails' which serve different functions. However, it could be more specific about the type of folder (e.g., IMAP, local) and does not clarify whether 'mailbox' is synonymous with 'folder'.

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 guidance is provided on when to use this tool versus alternatives such as 'move_email' or 'outlook_create_event'. The description does not mention prerequisites, typical use cases, or situations where this tool is preferable. Implicitly, it's for organizing emails, but explicit recommendations are absent.

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