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. It only states that a folder is created, without mentioning effects like duplicate handling, required permissions, folder_data structure, or any side effects. This is minimal and leaves important behavior undisclosed.

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 only one sentence and front-loaded, but it is under-specified rather than concise. It omits essential information about both parameters and the expected behavior, so the brevity is a weakness rather than a strength.

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 has two required parameters, one being a free-form nested object, and no annotations, this description is severely incomplete. An agent cannot determine what folder_data should include or how account_id should be used. The presence of an output schema does not make up for missing invocation guidance.

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 does not compensate. It does not explain what account_id represents or what folder_data should contain. Since folder_data is an unconstrained object with additionalProperties true, the agent receives no structural or semantic guidance for constructing valid input.

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 clear verb and resource: 'Create a new folder.' This distinguishes it from sibling tools like delete_folder and rename_folder. However, it is very terse and does not add any scoping detail about the account or folder data, so it stops just short of a top score.

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 gives no guidance on when to use this tool versus alternatives, no context for selecting it, and no exclusions. An agent must infer from the name that this should be used when a folder needs to be created.

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