Creates a new profile folder in the specified workspace.

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

Annotations already declare this is a non-read-only, non-idempotent, non-destructive creation. The description goes beyond them by disclosing the tariff/quota ceiling on folder count and the validity preconditions on workspace ID and location, which are real operational constraints. It still omits what happens on failure or whether the call is safe to retry.

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?

Purpose and precondition are correctly front-loaded, but the middle sentences describing a folder's identifier, name, location and profile quantity are largely expository filler already covered by the schema and don't help an agent invoke the tool. Four sentences for a simple three-parameter create is longer than needed.

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?

There is no output schema, yet the description never says what the call returns (presumably the new folder's identifier), which an agent would need for chaining. Annotations cover the safety profile and parameters are fully documented, so the remaining gap is the return value and the absence of alternative-routing 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?

Schema description coverage is 100%, so the schema already defines name, location (with the Local/Cloud enum and default) and workspaceId (-1 for default). The description restates location values and the folder's attributes without adding format, length, or uniqueness rules for the name parameter, so 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 first sentence gives a clear verb+resource ('creates a profile folder'), and the name plus surrounding description distinguishes it from create_proxy_folder and create_profile. However, it never explicitly names or contrasts with the sibling 'create_proxy_folder', so sibling differentiation is only implied by the noun.

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 supplies a precondition ('caller must ensure that the specified workspace ID and location are valid') and a quota constraint ('profile folders count is limited by tariff'), which implies when the call is appropriate. But there is no explicit when-to-use/when-not guidance and no routing to alternatives such as create_proxy_folder or the bulk/update variants.

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