create_directory

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

No annotations are provided, so the description carries the burden. It discloses recursive creation and drive compatibility, which is helpful. However, it does not state behavior when the directory already exists, permission requirements, or any error/return aspects. This is acceptable but leaves gaps.

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?

Two short sentences, front-loaded with the primary purpose followed by key behavioral traits. Every word earns its place, with no redundant filler.

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, single-parameter tool, the description is reasonably complete. It covers the core purpose, recursive behavior, and drive support. Missing details like existing-directory handling are not critical for basic usage, so the completeness is good, though not exhaustive.

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 provides 100% coverage for the single 'path' parameter, including a descriptive example. The description's mention of recursive creation reinforces that nested paths are valid but does not add standalone semantic value beyond the schema.

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 new directory'), specifies the resource (folder), and adds useful scope ('recursive creation', 'works on all drives'). It distinguishes itself from sibling file operations like write_file or delete_path, making the purpose unmistakable.

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 context is clear: use when you need to create a directory, including nested ones. There are no explicit alternatives or exclusions, but no sibling tool competes for this exact purpose, so the implied usage is sufficient.

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