get_behavior_insight

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

The readOnlyHint annotation already indicates a safe read operation. The description adds minimal context beyond that, only specifying the data source (app protocol traffic history). It does not disclose any additional behavioral traits such as time ranges, aggregation, or limitations, but also does not contradict 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?

The description is a single concise phrase with no wasted words. It is front-loaded with the verb and resource, making it easily scannable.

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 short description is mostly sufficient. However, it could benefit from elaborating what 'behavior insight' entails or the scope of the historical data, making it slightly incomplete but still adequate for a simple read operation.

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 has zero parameters, so the schema fully covers parameter semantics (100% coverage). The description is not required to explain parameters; baseline of 4 is appropriate.

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 '获取行为洞察：应用协议流量历史数据' clearly states the action (获取/get) and the resource (行为洞察/behavioral insight based on application protocol traffic historical data). It distinguishes from other get_* tools by specifying the data type, though 'behavior insight' remains somewhat vague.

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?

No guidance is provided on when to use this tool versus alternatives. The description does not reference any sibling tools or conditions for use, leaving the agent without direction on selecting this tool over similar log/audit getters.

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