mkdirs

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

Annotations are absent, so the description bears full responsibility. It reveals only that the tool creates directories recursively, but does not mention error handling, idempotency, permission requirements, or behavior when directories already exist. This lack of behavioral context is a significant gap.

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 concise sentence with no filler, front-loading the key behavior. It is appropriately sized for a simple tool.

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?

Despite its simplicity, the description leaves critical gaps: no path semantics, no error behavior, and no differentiation from the sibling create_directory tool. The presence of an output schema does not compensate for these missing details.

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?

The schema contains a single 'path' parameter with no description (0% coverage). The description does not specify the expected format, absolute vs relative, or any constraints for the path. It only indirectly indicates that path refers to the directory to create, which is insufficient.

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 the tool recursively creates multi-level directories in Nutstore, using a specific verb ('create') and resource ('multi-level directories'). The terms 'recursively' and 'multi-level' distinguish it from sibling tools like create_directory, which likely creates a single directory.

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 implies usage for creating nested directories but provides no explicit guidance on when to use this tool versus alternatives like create_directory, nor any exclusions. Usage context is implied by the phrase 'multi-level' but not explicitly stated.

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