Set User Usage Location

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

The description adds little beyond the annotations. It does not disclose potential side effects, permission requirements, or consequences of setting the location. Annotations already indicate a non-read-only, non-destructive mutation, but the description does not elaborate on the openWorldHint or any subtle behaviors.

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?

One short sentence that is immediately clear and front-loaded. No wasted words.

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 tool is simple, but the description omits information about return values, parameter meanings, and behavioral nuances. The prerequisite note is helpful, but overall the description leaves the agent with unanswered questions, especially given no output schema.

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 0% and the description does not explain the semantics of 'user' or 'usageLocation' (e.g., that usageLocation is a two-letter country code). The parameter names are self-explanatory to a degree, but the description fails to compensate for the lack of schema descriptions.

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 action ('Set a user usageLocation') and identifies the resource, with a helpful prerequisite note ('required before license assignment'). This distinguishes it from sibling tools like assign_license.

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 phrase 'required before license assignment' provides clear context for when to use this tool (prior to assigning licenses). However, it does not explicitly mention alternatives or exclusion scenarios, stopping short of full when/not guidance.

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