get_status

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It lists the output fields (connected, port, baud rate, device type), which is useful, but it does not explicitly state that the tool is read-only, what happens when not connected, or whether it may block or throw errors. The verb '获取' implies a read operation, but the description could be more transparent about side effects and edge cases.

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, front-loaded sentence that immediately conveys the purpose and key output details. It contains no fluff or repetition, making it highly concise and well-structured for quick comprehension.

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 (no parameters, no output schema, no annotations), the description is fairly complete: it states the purpose and enumerates the expected return fields. It falls short of describing error behavior or the exact response format, but for a status-checking tool, it covers the core information well.

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, so the schema coverage is trivially 100%. According to the rubric, the baseline is 4. The description adds no parameter information because there are none to describe; this is appropriate and does not detract.

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 verb '获取' (get) and the specific resource '当前连接状态' (current connection status), and enumerates the included details (connected, port, baud rate, device type). This is a specific, non-tautological purpose that effectively distinguishes the tool from siblings like connect, disconnect, and list_ports.

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 does not explicitly state when to use this tool over alternatives or provide exclusion criteria. However, the unique purpose of checking connection status is implied, which gives some guidance. There is no mention of 'use this when you need to verify connection' or 'use list_ports to enumerate available ports instead.'

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