query_domain_origin_host

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

No annotations are provided, so the description must disclose behavioral traits. It does not mention that this is a read-only operation, what the return value contains, or any side effects. For a query tool, the lack of return value explanation is a notable gap.

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 (4 Chinese characters) and front-loaded. It is efficient but could be slightly more structured with a brief explanation of the purpose or expected output.

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 simplicity (1 parameter, no output schema), the description is incomplete. It does not explain what the tool returns (the origin host value) or provide any additional context needed for an agent to use it correctly.

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 description coverage is 100% (one parameter 'domain' with description '域名'). The description adds no additional meaning beyond what the schema already provides, so the score is at baseline 3.

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 it queries the domain origin host (查询域名回源 Host). The verb 'query' and resource 'domain origin host' are specific, and it distinguishes from sibling tools like set_domain_origin_host (which sets) and other query tools for different attributes.

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. While the name implies its purpose, there is no explicit context about prerequisites or when not to use it. Given the large set of sibling tools, some usage advice would be beneficial.

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