test_alibaba_connection

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only states what the tool does (test connection status) without explaining what 'connection status' entails (e.g., network connectivity, API availability, authentication validity), what the output might include, or any side effects (e.g., rate limits, logging). For a diagnostic tool with zero annotation coverage, this is a significant gap in transparency.

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, clear sentence ('测试阿里云连接状态') that directly states the tool's purpose without any fluff or redundancy. It is appropriately sized and front-loaded, making it highly efficient for an agent to parse quickly.

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 tool's simplicity (0 parameters, no annotations, but with an output schema), the description is minimally complete. It states the basic purpose, but lacks details on behavior, output interpretation, or usage context. The presence of an output schema means the description doesn't need to explain return values, but it should still cover more operational aspects to be fully helpful.

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 0 parameters, and the input schema has 100% description coverage (though empty). The description doesn't need to add parameter semantics, so it meets the baseline expectation. A score of 4 reflects that the description is adequate for a parameterless tool, though it could theoretically mention why no parameters are needed (e.g., uses default configurations).

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 clearly states the tool's purpose as '测试阿里云连接状态' (test Alibaba Cloud connection status), which is a specific verb ('test') + resource ('Alibaba Cloud connection'). However, it doesn't distinguish this from potential sibling tools that might also test connections or verify cloud service availability, so it falls short of a perfect score.

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 alternatives. It doesn't mention prerequisites (e.g., authentication setup), scenarios where connection testing is needed, or how it differs from other diagnostic tools in the sibling list like those for monitoring CPU/disk usage. This leaves the agent with minimal context for tool selection.

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