Create Folder

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

With no annotations, the description carries the full burden of behavioral disclosure. It does mention the duplicate-folder behavior, which is useful, but it omits other behavioral traits such as whether relative paths are supported, permissions required, side effects, or what the success return looks like.

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 two sentences and both contribute useful information. The only slightly wasteful phrase is 'This function will', but overall it is efficient and front-loaded with the primary action.

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 simple one-parameter tool, the description covers the core operation and the duplicate case. However, it does not describe the success response, the structure of the duplicate message, or any path-related behavior, and there is no output schema to fill those gaps. Adequate but 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%, so the description must compensate for the undocumented 'folder' parameter. It does clarify that the folder parameter is the name, but it fails to specify whether it should be a bare folder name, a path, or any formatting constraints. Minimal compensation.

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 specific verb and resource: create a folder with a given name. Among sibling tools, only delete_folder relates to folders, and this describes the inverse operation, so there is no ambiguity.

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 about when to choose this tool over alternatives like bash or write_file, nor are any prerequisites or conditions stated. The description only explains what the tool does, not when to use it.

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