get_ipv6_lan_config

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

The description is consistent with the readOnlyHint annotation, confirming a safe read-only operation. However, it adds no extra behavioral context beyond what the annotation already provides, such as scope of returned data or network impact.

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—a single phrase—but it basically mirrors the tool name in Chinese. While it is not overly verbose, it misses the opportunity to add useful context like return value specifics or how it differs from similar getters.

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 the tool's simplicity (no parameters, output schema provided), the description is minimally sufficient. However, it does not clarify what specific 'IPv6 LAN settings' are included or how this relates to sibling tools, leaving some ambiguity for an agent.

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?

This tool has no parameters, and the input schema is fully covered. The description does not need to explain parameter semantics; the baseline for zero-parameter tools is 4, and the description does not introduce any ambiguity.

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 action ('获取' meaning 'get') and the resource ('IPv6 内网设置' meaning 'IPv6 LAN settings'). It is specific and the term '内网' distinguishes it from WAN-related siblings, though it does not explicitly name alternatives.

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 guidance on when to use this tool versus alternatives like get_ipv6_config or get_ipv6_wan_config. The description does not mention any prerequisites, exclusions, or scenarios for use.

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