Get Line Monitoring

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

readOnlyHint=true already declares this is a safe read, and the description adds the useful scope detail that data covers all WAN/LAN interfaces at once. It does not say whether results are a live snapshot, whether values are averaged over a window, or anything about refresh behavior, so it adds only modest context beyond the 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?

A single front-loaded sentence with the verb, resource, and the three returned metrics; no filler, no repetition of the title.

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?

With zero parameters and an output schema present, the description does not need to enumerate return fields, and it adequately conveys scope and metric coverage. The only real gap is routing guidance against the many adjacent monitoring tools, which is a usage-guidelines concern more than a completeness one.

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 nothing for the description to disambiguate; the baseline of 4 applies. The description correctly implies the call is unfiltered and returns all interfaces.

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+resource (获取线路监控) and scopes it precisely: real-time rate, connection count, and packet loss for all WAN/LAN interfaces. That distinguishes it from monitoring siblings like get_wireless_monitoring or get_load_monitoring, but it never names or explicitly contrasts with them.

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, no exclusions, and no mention of alternatives such as get_wan_status or get_load_monitoring. Usage is only weakly implied by the phrase '线路监控'.

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