get_ipv6_status

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

No annotations are provided, so the description carries the burden. It implies a safe read by naming return fields, and discloses the data domains covered, but says nothing about permissions, rate limits, or whether IPv6 must be enabled for meaningful output — a notable gap for a WAN-state query on a router.

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 compact sentence-fragment with the resource front-loaded and no filler. It sacrifices a grammatical predicate for density but stays readable and scannable.

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 no explanation, and a zero-parameter read tool is low complexity. What is missing is only the sibling routing that usage_guidelines would normally supply.

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?

Zero parameters, so there is nothing for the description to disambiguate; the baseline applies. The field enumeration is technically about return values rather than inputs, which is harmless here.

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?

A specific verb+resource ('IPv6 status') followed by an explicit inventory of the fields returned (connection type/enable, LAN address & prefix, DNS, assign type). That field list distinguishes it from siblings like router_status or wifi_info, though it never names those siblings directly.

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 explicit guidance on when to call this versus router_status or get_wifi_radio, and no stated prerequisites. The only signal is the implied scope of 'IPv6 WAN + LAN', leaving the agent to infer routing from the name alone.

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