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

With no annotations present, the description carries the full behavioral disclosure burden. It does this well by revealing a meaningful side effect: the caller becomes the folder's owner, which is what enables sharing. It stops short of covering failure conditions, duplicates, or visibility, but the ownership consequence is important and non-obvious.

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?

Three sentences, front-loaded with the core action and then expanded with the conceptual model. Each sentence adds information, though the middle sentence is slightly roundabout ('access is granted on one' is a bit indirect). Overall it is efficient and readable.

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 create operation with one required parameter and no output schema, the description is largely complete: it covers purpose, usage timing, and the key ownership consequence. It does not describe return behavior or failure cases, but given the simple shape of the tool this is a minor gap.

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 description coverage is 100%, so the schema already explains both token and folder_path, including ordering and an example. The description adds no additional parameter-level meaning, which is acceptable because the schema carries the load; baseline 3 applies.

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 opens with a clear verb+resource pairing ('Make a folder') and goes further by defining why a folder is created: it is the unit that holds content and carries access for a project. This distinguishes create_org_folder from share/list-related siblings such as share_org_folder and list_org_folders.

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?

It clearly states when to use this tool: to start a project before putting anything in it, since content and access both attach to a folder. It does not explicitly name excluded alternatives or when not to use it, but the usage context is concrete and actionable.

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