set_domain_origin_host

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

No annotations are provided, so the description carries the full burden. It does not disclose behavioral traits such as whether this is an update, if it requires specific permissions, or if it is destructive. It merely restates the tool's function.

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 very concise (a single 4-word Chinese sentence). It is not verbose, but also lacks structure or supplementary information. It is minimally acceptable but not well-structured.

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 simple parameters, the description does not cover return values or prerequisites. While the schema covers parameter details, the description fails to provide higher-level context about the operation's effects or success criteria.

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 does not elaborate on the meaning of origin_host_type values or the conditional requirement of origin_host.

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 '设置域名回源 Host' clearly states the action (set) and the resource (domain origin host). It is specific and distinguishes from sibling tools like query_domain_origin_host (read) and set_domain_origin (sets the origin, not the host).

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 vs alternatives. There is no mention of prerequisites, context, or why one would choose this over related set_ tools such as set_domain_origin or set_domain_https.

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