get_device_model

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

With no annotations provided, the description carries the full burden. It indicates a read-only 'Get' operation and gives example return values, which is helpful. However, it does not disclose potential error cases, return format, or any device-specific quirks beyond the examples.

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?

A single, focused sentence that front-loads the verb and resource and adds useful examples. There is no wasted text or repetition.

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 getter with an output schema present, the description is fully sufficient. It states exactly what is retrieved and gives representative values; nothing else is needed to call the tool correctly.

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 takes zero parameters, so the default baseline of 4 applies. There is nothing to explain about parameter semantics, and the schema coverage is trivially complete.

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 uses the specific verb 'Get' with a clear resource, 'WLAN Pi hardware model', and provides concrete examples ('WLAN Pi Pro, R4, M4'). This precisely identifies what the tool returns and distinguishes it from sibling getters like get_device_info or get_device_stats.

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 clearly implies the usage condition: use this tool when the WLAN Pi hardware model is needed. While it does not name alternative tools or explicitly exclude them, the purpose is so specific that selection among the many getter siblings is unambiguous.

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