set_domain_ipv6

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 does not mention that this operation modifies domain IPv6 settings, that it requires appropriate permissions, or whether changes are immediately effective or require propagation. For a mutation tool, this omission is significant.

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 short (four words in Chinese), but it is under-specified rather than concise. It provides no guidance beyond the tool's name, and the brevity leads to ambiguity about the exact effect of the operation.

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 no output schema and low complexity (only two parameters), the description is insufficient. It does not explain the outcome of setting IPv6, any domain constraints, or how it interacts with other settings. An agent would lack key context for correct invocation.

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 100%, so the baseline is 3. The description adds no additional meaning beyond the schema—it merely restates the domain and enable parameters. The schema already explains the enum values ('0=关闭, 1=开启'), so the description does not enhance understanding.

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 '设置域名 IPv6' clearly indicates the action (set) and resource (domain IPv6), making it easy to understand the tool's purpose. It aligns with the tool name, though it lacks differentiation from sibling tools like 'set_domain_force_https' or 'set_domain_http2'.

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, such as the related 'query_domain_ipv6' for reading or other 'set_' siblings for different configurations. No context about prerequisites or typical usage scenarios is given.

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