get_hotspot_stations

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

No annotations are provided, so the description carries the behavioral disclosure burden. It does disclose an important behavior: the tool errors when the device is not in hotspot mode, and it notes that iface is auto-detected when omitted. However, it leaves the read-only / no-side-effect nature implicit rather than stating it explicitly.

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 three short, purposeful sentences with the main action front-loaded. The parameter explanation is compact and useful, with no filler or redundancy.

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 simple getter with one optional parameter and an output schema, the description covers the purpose, the key error condition, and parameter behavior. The main remaining gap is the lack of positioning relative to the similarly named get_hotspot_clients, but this does not prevent a competent agent from invoking 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?

Schema description coverage is 0%, and the description compensates well by defining iface as an optional AP interface name and explaining that it is auto-detected if omitted. This adds meaningful semantic information beyond the schema's generic string/null type and default null.

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 a specific verb and resource ('List stations connected to the hotspot AP interface'), so the core purpose is clear. However, it does not differentiate itself from the sibling tool get_hotspot_clients, whose name suggests a very similar or overlapping function.

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 implies the intended context by stating that an error is returned when the device is not in hotspot mode, which tells the agent this tool is only relevant in hotspot mode. But it gives no explicit when-to-use guidance and does not mention any alternative such as get_hotspot_clients.

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