Get Ipv6 Lan Config

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

The readOnlyHint annotation already establishes that this is a safe read operation. The description adds only the content scope (prefix delegation, RA, DHCPv6); it does not disclose permissions, side effects, or return behavior beyond what annotations and the output schema provide.

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 front-loaded phrase with no filler. Every part identifies the resource or scope; nothing needs trimming.

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 and a readOnly annotation, the description identifies the resource and covered subareas sufficiently to invoke it. It could better differentiate from related IPv6 config tools, but it covers what is needed for a simple read.

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?

There are no input parameters, so there is no parameter semantics to document. Per the rubric, zero parameters baseline to 4.

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 states a specific verb (获取/get) and resource (IPv6 内网设置/LAN settings) and enumerates covered subareas (prefix delegation, RA, DHCPv6). It implicitly distinguishes from the adjacent WAN tool by saying 内网/LAN, though it does not name the sibling explicitly, so it is clear but not fully differentiated.

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?

No when-to-use guidance or prerequisites are given. The description does not distinguish when an agent should call this versus get_ipv6_config or get_ipv6_wan_config, leaving selection implicit.

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