Create a folder

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

Annotations supply idempotentHint=true and openWorldHint=true, so the bar is lower. The description adds useful behavior beyond them: it creates any missing parent folders. However, it does not disclose authorization needs, error behavior, or what happens when the folder already exists beyond the idempotency annotation.

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 a single front-loaded sentence with no wasted words. It efficiently conveys the main action and the recursive-parent behavior. It is appropriately concise, though not richly structured or expansive.

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 create operation with no output schema, the description covers the basic action and project context. Annotations cover idempotency and open-world behavior. However, the required 'path' parameter remains undocumented, and authentication/permission expectations are absent, leaving notable gaps.

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 50%: the optional 'project' parameter has a schema description, but the required 'path' parameter has none. The description does not compensate by explaining the format or meaning of 'path' (e.g., relative path, nesting rules), so an agent still lacks key parameter semantics.

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 specific verb and resource: 'Creates a folder ... in a project.' It also clarifies that missing parent folders are created recursively. It does not explicitly differentiate itself from sibling tools like create_project, which is the only gap keeping it from a 5.

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 such as create_project, upload_file, or move_file. Usage is only implied by the verb 'Creates', with no exclusions or prerequisites stated.

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