create_folder_tool

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

No annotations are provided, so the description carries full burden. It discloses that it creates all necessary parent folders and returns creation status. However, it does not mention what happens if a folder already exists or any permission requirements, which would strengthen transparency.

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 well-organized with clear sections for usage, not-usage, and returns. It is concise yet thorough, with every sentence adding value.

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 no output schema, the description covers purpose, usage, behavior, and return format. It could be improved by detailing error scenarios or the exact placeholder file behavior (e.g., .gitkeep vs README.md), but overall it is sufficiently complete for a folder creation tool.

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 67%, so baseline 3. The description adds value by explaining that folder_path supports nested paths and that placeholder creation defaults to true. However, the 'ctx' parameter is not described, and the schema already covers the other two parameters adequately.

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 it creates a folder including all parent folders. It distinguishes itself from sibling tools like create_note_tool by focusing on folder creation only, and provides explicit examples of when to use.

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 explicitly lists when to use (e.g., setting up project structure, deep hierarchies) and when NOT to use (e.g., when notes create folders automatically). This provides clear decision rules for the agent.

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