query_domain_http3

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

No annotations provided. Description implies a read-only query ('query') but does not explicitly state that no state changes occur. No mention of side effects, rate limits, or permissions. With zero annotation coverage, the description should provide more behavioral context.

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?

Description is a single sentence with no wasted words. However, it is slightly underspecified; could benefit from a brief statement about the return value. Still, conciseness is good.

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 simple query tool with one parameter and no output schema, the description is minimally complete: it states the action and resource. However, it lacks behavioral details and usage context, which would help an agent decide to invoke it. No output schema means description could hint at return format, but not required.

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 has 1 parameter 'domain' with description '域名' (domain), and schema coverage is 100%. The description adds no additional meaning beyond what the schema already provides. Baseline 3 is appropriate.

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?

Description clearly states 'query domain HTTP/3 settings', which is a specific verb and resource. It distinguishes from siblings like query_domain_http2 or set_domain_http3, though the distinction relies partly on the tool name. The purpose is clear.

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 guidance on when to use this tool vs alternatives (e.g., query_domain_http2 for HTTP/2, or set_domain_http3 for modifications). No context about prerequisites or conditions.

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