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

The description transparently states the tool's behavior: creates folders, recursively creates missing parents, and does nothing if the folder already exists. This aligns with the annotations (idempotentHint=true, readOnlyHint=false, destructiveHint=false) and adds useful context about parent creation that annotations alone do not convey.

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 exceptionally concise, using three short sentences to cover the core action, parent-creation behavior, and idempotency. Every sentence adds distinct value without redundancy or fluff.

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?

The description covers the essential functional details and the parameter adequately. However, given the presence of the sibling tool octopus_make_folder, it lacks a clarifying note about when to prefer this tool over the sibling, which slightly reduces completeness in the broader tool context.

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 description of the 'path' parameter is clear and includes an example ('/Tax/2026/'). This adds practical context beyond the schema's minimal string type and required flag, helping agents understand the expected format and nesting behavior.

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 verb 'create' and resource 'folder', with additional details about auto-creating parents and idempotency. However, it does not explicitly distinguish itself from the sibling tool octopus_make_folder, which appears to have a nearly identical purpose.

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 provides no explicit guidance on when to use this tool versus alternatives. It implicitly suggests it can create nested paths and is safe to call on existing folders, but it never references the similar octopus_make_folder or other folder-related tools, leaving selection ambiguous.

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