Get Priority Domain Settings

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

readOnlyHint=true already tells the agent this is a safe read, so the description carries little extra burden. It adds no behavioral context such as scope of the settings, whether defaults are returned, or any access requirements; the category path is navigational rather than behavioral.

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?

A single, front-loaded phrase with no filler or repetition. It is appropriately sized for a zero-parameter getter, though it is terse enough that it could carry one more clause of routing value.

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 explained, and annotations cover the safety profile. Still, for a tool embedded in a dense flow-control family, the description does not give enough to distinguish it from sibling getters or indicate when its result is relevant.

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 per the rubric the baseline is 4. There is nothing for the description to clarify beyond what the empty schema already conveys.

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?

States a specific verb (get) and resource (priority domain settings) and adds a navigation path ('智能流控 → 优先域名') that places it in the smart flow-control category. However, it does not differentiate itself from sibling getters like get_flow_control_strategies or get_flow_control_lines, leaving the agent to infer which 'settings' this returns.

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 gives no when-to-use, no prerequisites, and no mention of alternatives, despite a large family of flow-control and settings getters in the sibling list. The category path hints at the domain but provides no selection guidance.

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