get_connection_status

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

With no annotations, the description carries the full behavioral burden. It signals a non-mutating read ('读取') and emphasizes 'real-time', implying live state and no caching, which is useful. It does not state permission requirements, whether the call is cheap/safe to repeat, or how failures surface.

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 sentence enumerating the four returned fields, front-loaded with the most important part (real-time session). Nothing wasted, nothing repeated from the schema.

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 no output schema, enumerating the returned fields is exactly the right compensation, since there is no structured return definition. Only the read-only/non-destructive nature and auth expectations are unstated.

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 parameter semantics is a baseline 4. The description correctly adds no parameter discussion and instead spends its words on the returned content.

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 names a specific resource and enumerates its parts: real-time session, software version, local endpoint, and enabled capabilities. An agent can tell this is a status/diagnostics read, distinct from the document and sprite siblings. It never uses an explicit verb like 'returns' or 'reads' in a named form, but the resource is unmistakable.

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 guidance on when to call this versus other tools, no prerequisites, and no mention of when it is unnecessary. The agent must infer that it is a diagnostic check, likely at startup or before other operations.

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