Get Dynamic Dns Config

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

readOnlyHint=true already declares the safety profile, and the description contributes nothing further — no scope, no auth requirements, no caveats about what the returned configuration covers. With annotations carrying the safety burden, the description still needed to add behavioral context and adds none.

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 a single short phrase with no padding, but its brevity stems from under-specification rather than discipline — it conveys no information beyond the title. It is appropriately sized only in the trivial sense.

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?

An output schema exists, so return values need not be described, and with zero input parameters the surface area is small. However, the description still fails to explain how this config tool relates to the sibling get_ddns_config, leaving a real ambiguity for tool selection.

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?

The tool takes zero parameters, so there is no parameter semantics to document; the schema is fully closed with additionalProperties=false. Baseline 4 applies for a parameterless tool.

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 '获取动态域名 (DDNS) 配置' is essentially the tool title rendered in Chinese, restating verb (get) and resource (DDNS config) without adding any distinguishing detail. It does not differentiate from the closely named sibling get_ddns_config, so an agent cannot tell what this returns that the other does not.

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 when-to-use guidance at all: no mention of prerequisites, no reference to alternatives such as get_ddns_config or get_dns_config, and no indication of when a caller would reach for this tool. The description merely asserts existence.

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