TDQS

C2.7/5.0
Behavior2/5

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

No annotations are provided, so the description carries the full burden. It does not disclose whether the directory must not already exist, whether parent directories are created, whether permissions are needed, or what happens on failure. This is a mutation tool with no side-effect or error information.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is one short, front-loaded sentence with no filler or redundancy. However, its brevity comes from under-specification rather than efficient coverage of the tool's important details.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given no annotations and an output schema that is not provided, the description is too minimal to allow correct invocation. It lacks essential context about error handling, existing-directory behavior, recursive creation, and the role of serial, making it incomplete for a real-world agent.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, and the description adds only minimal meaning by implying that remote_path is the directory to create. The optional serial parameter is completely unexplained, and there is no detail about path format, required permissions, or default behavior.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states a specific action ('create') on a specific resource ('directory') on the device, matching the tool name make_dir. It is distinguishable from siblings like list_files, delete_path, and move_path, though it does not explicitly differentiate itself from any alternative.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no guidance on when to use this tool versus alternatives. The description only states what the tool does, not when it should be preferred over other file-system tools such as push_file or move_path.

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