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

Annotations already declare readOnlyHint=false and openWorldHint=true, indicating a write operation with possible external effects. The description adds the useful detail that missing parent folders are created, which is a behavioral trait. However, it does not disclose potential side effects, permission requirements, or failure modes beyond that.

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, efficient sentence with a clear title and the core behavior front-loaded. It includes the recursive parent folder detail without padding. The category tag adds metadata without bloating the text.

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 one-parameter tool with no output schema, the description covers the main behavior and the key nuance of recursive folder creation. It does not explain return values or error handling, but those are not critical for such a straightforward operation. The main gap is the lack of contrast with octopus_mkdir, which is a contextual completeness issue, but overall it is fairly complete.

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 covers 100% of the parameter and already provides an example ('/Clients/Acme'). The description adds meaning by explaining that parent folders are created implicitly, which goes beyond the schema's literal path interpretation. This enriches the agent's understanding of the path parameter.

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?

States a clear verb ('create'), resource ('folder'), and scope ('in the user's file storage'). Mentions the recursive creation of missing parent folders. However, it does not explicitly differentiate from the sibling tool octopus_mkdir, which likely serves a similar purpose, so it misses the chance to disambiguate.

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 explicit guidance on when to use this tool versus octopus_mkdir or other sibling tools. The recursive parent creation is implied but not framed as a differentiator or condition. The description provides no 'use when' or 'instead of' cues.

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