Get Ping Interfaces

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

readOnlyHint=true already tells the agent this is a safe read with no side effects, so the description is not obligated to restate safety. It adds only the fact that the returned interfaces are Ping-capable egress interfaces, with no detail on how they are ordered or filtered. Adequate but thin given annotations cover the safety profile.

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 short phrase that is front-loaded and wastes no words. It is efficient rather than padded, though its brevity borders on under-specification.

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 described, and zero params keeps the surface small. However, the description never ties this tool to the ping workflow or names the sibling it complements, leaving the agent to infer why it exists alongside ping_test and stop_ping.

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 baseline of 4 applies. The description correctly signals a no-argument listing operation.

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 gives a specific verb+resource: retrieve the egress interfaces available for Ping. It is clear what the tool returns, though it does not differentiate itself from similarly named siblings such as get_capture_interfaces or get_wan_status that also expose interface lists.

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 guidance, no prerequisite, and no mention of the related ping_test / ping_result tools this presumably feeds into. The agent must infer the workflow (pick source interface, then run ping) entirely on its own.

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