Get Flow Control Lines

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

The readOnlyHint annotation already marks this as a safe read, and the description adds no behavioral context beyond that. It says nothing about return format, pagination, caching, or any other operational trait, so it provides no value beyond the structured annotation.

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?

It is a single front-loaded sentence with zero filler, perfectly sized for a simple zero-parameter read tool. Nothing is redundant or missing from a conciseness standpoint.

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 tool has no parameters, an output schema, and a readOnlyHint, the description is nearly complete for safe invocation. The remaining gap is the absence of any usage context relative to sibling flow-control tools, which keeps it from a perfect score.

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 are no parameter semantics for the description to clarify. The baseline for a parameterless tool is 4, and nothing here suggests that baseline should be adjusted downward.

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 states a specific verb (获取) and resource (流控线路配置), and adds the UI location (智能流控 → 流控线路), which reliably distinguishes it from the sibling get_flow_control_strategies and the setter set_flow_control_line. It is clear but does not explicitly name or contrast the alternatives, leaving that to inference.

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 guidance, prerequisites, or alternative tools. It only restates what is retrieved, so an agent receives no help deciding between this and get_flow_control_strategies or any other flow-control endpoint.

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