mkdir

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

Annotations are absent, so the description carries the burden. It mentions return type (dict with 'message' and 'code') but fails to disclose critical behavior such as error handling (e.g., if directory already exists), required permissions, or whether parent directories are created.

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 concise (80 words) and well-structured with Args, Returns, and Examples. Every sentence is informative, with no waste.

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 the tool's simplicity (2 required parameters) and presence of an output schema (though not shown), the description adequately covers purpose, parameters, return value, and examples. Minor lack of behavior on existing directories prevents a perfect score.

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 0%, so the description must fully explain parameters. It does so clearly: endpoint_id is 'The UUID of the endpoint' and path is 'Path where the directory should be created', adding substantial meaning beyond the property names.

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 the action 'Create a directory' on a specific resource 'Globus endpoint', with a specific verb and resource. It distinguishes from sibling tools like ls, rm, transfer, which have different purposes.

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?

No guidance on when to use this tool versus alternatives. It does not mention prerequisites or scenarios where mkdir is appropriate compared to other tools like transfer or rename.

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