get_arp_log

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

The description adds no behavior beyond the readOnlyHint annotation; it simply restates the tool name. It does not mention what the ARP log contains, whether it is historical or current, or any output characteristics.

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 extremely concise with zero wasted words, but it is terse to the point of providing minimal semantic value. It is front-loaded and readable.

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 no-argument getter with an output schema, the description is adequate but thin. It does not explain the nature of the ARP log (e.g., event history vs. current table), leaving some ambiguity for the agent.

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 and an empty schema, so parameter descriptions are not needed. The baseline of 4 applies because there is no parameter complexity to document.

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 states a clear action and resource: '获取 ARP 日志' ('Get ARP log'). It identifies the specific ARP log among many sibling log tools, though it does not add scope details or explicit differentiation from similar get_*_log tools.

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 instead of alternatives like list_arp_bindings or get_connection_table. There are no usage conditions, prerequisites, or exclusions.

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