get_traffic_audit_by_user

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 no further behavioral context, such as what data is audited, time ranges, or any side effects. Since annotations cover the safety profile, the description adds minimal value but does not conflict.

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 sentence that immediately conveys the tool's function. It is appropriately sized with no unnecessary filler.

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 zero-parameter schema and the presence of an output schema, the description is adequate for understanding the tool's basic purpose. However, it omits any context about what 'account' refers to or how this relates to the MAC-based sibling, though output schema handles return details.

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 input schema has zero parameters, and schema coverage is 100%. The description contains no parameter information, but with no parameters to document, the baseline 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 '按账号审计终端流量' clearly states the tool audits terminal traffic by account, using a specific verb and resource. The 'by account' qualifier distinguishes it from the sibling get_traffic_audit_by_mac, though it does not explicitly name the alternative.

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 provides no guidance on when to use this tool versus the similar get_traffic_audit_by_mac. It simply states what the tool does, with no exclusions or alternative references, so the agent receives no usage direction.

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