ping

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

With no annotations provided, the description must fully disclose behavioral traits, but it only restates the purpose. It does not mention side effects (though likely none), return behavior, success/failure indication, or whether the operation is read-only. This is functionally a tautology of the tool name 'ping'.

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 sentence with no wasted words. It front-loads the verb and purpose, making it immediately clear what the tool does. Ideal conciseness.

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 simple tool, the description is too sparse. There is no output schema, so the description should explain what the tool returns (e.g., round-trip time, success status). It also omits any usage examples or preconditions. The description lacks enough context to use the tool effectively, especially given the ambiguous parameter.

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?

Although schema coverage is 100%, the parameter description '姓名' (name) is generic and misaligned with the tool's purpose of testing a server connection. The description does not clarify what 'name' refers to (e.g., server hostname, connection identifier). This semantic gap makes the parameter ambiguous and the description fails to compensate.

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 '测试服务器连接' clearly states the tool tests a server connection, which is a specific action on a specific resource. It distinguishes itself from sibling tools like image or video by indicating a network connectivity check. However, it does not explicitly detail what kind of test (e.g., ICMP ping) or the exact resource being tested.

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 given about when to use this tool or how it compares to alternatives. The description simply states what it does but offers no context for selection, such as implying a health check or network troubleshooting scenario. Sibling tools are unrelated, so no differentiation is provided.

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