get_monitor_overview

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

With no annotations, the description carries the full load, but it is a zero-parameter aggregate read and the output schema already defines the return shape, so the burden is light. It does state that no parameters are needed and that the result is a dashboard summary, yet it says nothing about access scope, whether the data is cached or real-time, or any rate limits.

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?

Purpose and content list are front-loaded in the first sentence; the query examples and the no-parameters note are short and each serves a routing or clarity function. No filler sentences.

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 zero-parameter read tool with an output schema that already documents the returned fields, the description is sufficient: it names the resource, lists the summary categories, and clarifies invocation. The only real gap is the absence of guidance on how this differs from sibling summary tools.

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, which is the baseline-4 case. The closing '无需参数' merely confirms what the empty schema already shows and adds no further semantics.

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 and resource ('获取所有监控的总览大盘数据') and enumerates the contents (active monitor count, today's collection/alerts, per-site distribution). This distinguishes it from the sibling get_monitor_list, which lists individual monitors rather than aggregating them, though the description never says so explicitly.

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 three example user phrasings ('给我一个监控总览', '我的所有商品监控情况怎样', '大盘数据看看') give an agent concrete routing signals for when this tool applies. However, no alternative is named and no case is excluded, so the agent must infer that get_monitor_list or get_price_summary cover narrower questions.

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