ping

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

No annotations are supplied, and the description adds no behavioral information such as whether the check is read-only, what request is sent, timeout or failure behavior, or what result is returned. Calling it a “test” alone does not disclose those traits.

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 phrase is extremely compact and contains no filler. However, its brevity omits the target and result semantics, making it under-specified rather than fully efficient.

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?

A zero-argument connectivity check is simple, but the lack of annotations and an output schema leaves important context entirely to the description. It does not say what is tested or how success and failure are represented.

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 declared parameters, so there are no parameter meanings for the description to clarify and the baseline score applies. Although additionalProperties is allowed, no specific optional inputs are documented that the description would need to explain.

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?

“连通性测试” means “connectivity test,” so it conveys a diagnostic purpose rather than merely repeating “ping.” It does not identify whose connectivity is tested or distinguish the tool from siblings such as ACTION_NETWORK_STATUS or ACTION_HTTP_REQUEST.

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 only implied use is a generic connectivity check. There is no guidance on when a ping is appropriate, what prerequisites exist, or when to use a sibling network tool instead.

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