Create folder

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

Annotations already declare readOnlyHint=false, destructiveHint=false, and openWorldHint=false, so the agent knows the safety profile. The description adds a genuinely useful trait beyond that — that intermediate directories are created recursively. It does not state the behavior when the folder already exists or whether permissions are required, so it earns credit but not full marks.

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?

Two short sentences with zero filler; the recursive-creation behavior is front-loaded with the core 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 single-parameter creation tool with no output schema, annotations covering the safety profile, and a fully documented param, the description contains what an agent needs. Minor gaps are existing-folder behavior and error semantics.

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 coverage is 100%, with the 'path' parameter fully documented as an absolute cloud path with an example, so the schema is doing the heavy lifting. The description implies the path may include missing intermediate segments, but adds no further syntax beyond that.

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 names a specific verb ('Create') and resource ('a folder in the Filen cloud'), so the agent can instantly distinguish it from siblings like write_file and upload_file. It is clear without being an explicit sibling comparison.

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 explicit guidance on when to create a folder versus writing a file that implies the path, nor on prerequisites such as authentication or parent-folder ownership. The usage is only implicitly derivable from the verb.

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