get_device_name

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

With no annotations provided, the description fully carries the burden of behavioral disclosure. It explicitly details the underlying API call ('GET /api/name via SettingsApi.get_name()') and the return structure ('Returns a NameInfo object containing: name (str)'). This is transparent for a read-only operation, though it does not address error conditions or network requirements, keeping it from a 5.

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 compact and well-structured. It front-loads the core purpose, then groups implementation detail, return data, and use case into clear sections. Every sentence contributes information without redundancy, making it highly readable and appropriately sized.

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 zero-parameter, no-output-schema tool, the description is exceptionally complete. It covers what the tool does, how it works (API call), what it returns (with example), and when to use it. Combined with the sibling context, an agent has everything needed to decide on and invoke this tool.

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 tool has zero parameters, which yields a baseline of 4 per the rubric. The description does not need to elaborate on parameters; it instead enriches the tool's semantics by describing the return value, which adds meaning beyond the empty schema.

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, specific verb-resource pair: 'Retrieve the device name configured on the Busy Bar device.' This unambiguously states the tool's function and distinguishes it from sibling get_* tools, which target transport, account, status, etc. No ambiguity exists.

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 a clear use case: 'Confirm or audit the display name shown on the device, especially useful in multi-device setups.' This gives context for when to use the tool, though it does not explicitly name an alternative or state when not to use it, so it stops short of a 5.

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