get_device_ip

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states the tool returns IP addresses as JSON, which is helpful, but doesn't mention important behavioral aspects like whether this requires network permissions, if it returns both IPv4 and IPv6 addresses, whether it's a read-only operation, or if there are any rate limits or constraints.

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 extremely concise with just two sentences. The first sentence states the purpose, the second describes the return format. There's no wasted text, though some might argue it's too brief given the lack of behavioral context. The structure is front-loaded with the core purpose.

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 that this is a simple read operation with 0 parameters and an output schema exists (though not shown), the description is minimally complete. However, for a device information tool with no annotations, it should ideally mention more about what 'all IP addresses' means (network interfaces, loopback, etc.) and any behavioral constraints.

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 0 parameters with 100% schema description coverage, so the baseline is 4. The description doesn't need to explain parameters, and it doesn't attempt to describe any. This is appropriate for a parameterless tool.

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's purpose: 'Get all IP addresses of the device' - a specific verb ('Get') and resource ('IP addresses'). It distinguishes from siblings like get_device_id or get_device_info by focusing specifically on IP addresses. However, it doesn't explicitly differentiate from potential similar tools that might exist elsewhere.

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 guidance on when to use this tool versus alternatives. It doesn't mention prerequisites, context, or compare it to sibling tools like get_device_info which might also provide IP information. There's no 'when-to-use' or 'when-not-to-use' information.

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