Files Create Folder

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

The description adds no behavioral detail such as whether parent directories are created, what happens if the folder already exists, or whether permissions are needed. The annotations provide only non-destructive/idempotency hints, and the description does not supplement them with any real behavior.

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 short, but brevity here is under-specification rather than effective conciseness. It front-loads no usable information and spends its only sentence on boilerplate framing.

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 mutating filesystem operation with one required path parameter, this description is functionally empty. Even with the output schema present, an agent cannot determine basic semantics, error behavior, or expected input format from this definition.

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 description needed to explain the meaning of the required 'path' parameter, but it does not. The agent is told a path is required without any clarification of whether it is a target directory, a parent path, or a full path including the new folder name.

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 only says it is a 'delegated Apple domain tool' exposed through Apple-Tools-MCP, which essentially restates the name without explaining the operation. It never explicitly states that this tool creates a folder at a given path, so a new agent must infer the entire purpose from the name alone.

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 about when to use files_create_folder, what prerequisites exist, or how it differs from sibling file operations like files_move_path or files_list_directory. The agent is left without any decision support for selecting this tool over alternatives.

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