get_device_status

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

No annotations are provided, so the description carries the full behavioral burden. '读取' implies a read-only operation and the description lists the state categories (connection, profile, GATT), but it does not disclose side effects, permissions, rate limits, or whether the call is safe to repeat. The output schema covers return values, but behavioral context remains thin.

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, front-loaded sentence with no filler. It efficiently conveys what state is read and whose state it is.

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 zero-parameter read tool with an output schema, the description is mostly complete: it names the state categories being returned. It lacks usage context relative to connect/disconnect siblings, but given the low complexity and available output schema, the gap is minor.

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 the schema does not require parameter-level description. The description adds no parameter details, but none are needed, making this a baseline 4.

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 states a specific verb (读取/read) and resource (device connection, profile, and GATT status held by MCP itself). It distinguishes this from querying a device directly by specifying that the status is MCP-held. However, it does not explicitly differentiate from siblings such as list_devices or connect_device.

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 explicit guidance on when to use this tool versus alternatives like list_devices or connect_device. Usage is only implied by the tool name and purpose; no when-to-use, prerequisites, or exclusions are stated.

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