Create Storage Box Subaccount

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

Annotations indicate it is not read-only or destructive, and description confirms it creates a subaccount. However, it does not disclose potential side effects, authentication needs, or behavior under duplicates. Annotations partially cover safety, but description adds limited behavioral context.

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 14-word sentence that is entirely front-loaded and to the point. There is no unnecessary information, and every word contributes to understanding the tool's primary action.

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?

Given the tool has 7 parameters, nested objects, and no output schema, the description is too brief. It does not describe the return value, confirm that the subaccount is created immediately, or address any potential responses. The agent lacks context on what to expect after invocation.

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 coverage is 100%, so baseline is 3. The description reiterates the purpose of home_directory, password, and access_settings but does not add new meaning beyond the schema descriptions. It adds no novel parameter semantics.

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 tool creates a subaccount on a Storage Box with scoping to a home directory, password, and access settings. It distinguishes from siblings like create_storage_box (creates the box itself) and update/delete subaccount tools.

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 vs alternatives, nor any when-not-to-use conditions. It does not mention prerequisite steps or exclusion criteria.

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