get_ip_address

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

With no annotations, the description carries the full burden. The word 'Return' implies a read-only query, which is the key behavioral trait, and 'default wlan0' discloses defaulting behavior. However, it says nothing about error/empty behavior (e.g., no address on the interface) or connectivity requirements.

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 sentence that front-loads the action and resource, with the default parenthetically tucked in. Zero 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?

An output schema exists, so return values need not be explained, and the tool is a simple read. But the 'serial' parameter and any failure conditions are left unaddressed, leaving the definition adequate rather than complete.

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% for two parameters, so the description must compensate. It explains the 'iface' parameter ('on an interface, default wlan0'), which is genuinely useful, but says nothing about the 'serial' parameter, leaving half the inputs undocumented.

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?

States a specific verb and resource: 'Return the device's IPv4 address on an interface'. An agent can tell this retrieves a network address, distinct from siblings like get_prop or get_device_properties. No explicit sibling differentiation, but the resource is precise.

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?

There is no when-to-use guidance, no mention of alternatives (e.g., get_prop/get_setting for network values), and no prerequisites such as needing a connected device. Usage is only inferable from the purpose, which is thin for a tool among many get_* siblings.

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