Get Behavior Insight

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 bar is lower. The description adds the one behavioral fact that the data is historical (as opposed to realtime), but discloses nothing about time range, granularity, aggregation, retention, or latency, which matters for an 'insight' endpoint.

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; appropriately sized for a zero-parameter tool. It is on the terse side, but nothing in it is wasted or padded.

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 there are no parameters to document. However, scope is left entirely open: the description does not say whose traffic (all terminals? one user?), over what window, or what 'insight' concretely contains, leaving an agent unable to predict whether the result answers its question.

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 4 baseline applies. The absence of any filtering parameters also means the agent should expect an unscoped, whole-system result, which the description hints at but never states.

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 names a clear verb (获取/get) and a resource (行为洞察/behavior insight) and then specifies the resource as 应用协议流量历史数据 (application-protocol traffic history), so an agent knows what data domain it returns. It offers no differentiation from lookalike siblings such as get_traffic_audit_by_mac, get_traffic_audit_by_user, or list_app_protocol_rules, which is the main gap.

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 statement, no prerequisites, and no mention of alternative tools that also surface traffic or protocol data. The agent must infer usage purely from the name.

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