Get Registration Status

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

The readOnlyHint annotation already establishes this is a safe read. The description's only added behavioral note ('faststart only accepts TYPE=all') references a TYPE parameter that does not exist in the schema for this parameterless tool, so it introduces confusion rather than useful behavioral context.

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?

Very short and front-loaded: purpose in the first line, supplemental note second. It is appropriately sized, though the second sentence is cryptic and arguably does not earn its place.

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?

With zero parameters, a read-only annotation, and an output schema that covers return values, the description's burden is light and mostly met. The main gaps are the unexplained overlap with get_cloud_binding_status and the unhelpful TYPE=all note.

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 there are no parameter semantics for the description to clarify; the baseline is 4. The stray TYPE=all remark refers to a parameter absent from the schema, which is odd but does not misdescribe an actual input.

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 clear verb and resource ('获取云服务注册/绑定状态' = get cloud service registration/binding status), so an agent knows what it retrieves. However it does not differentiate itself from the near-identical sibling get_cloud_binding_status, leaving the overlap unresolved.

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 statement of when to use this tool versus alternatives, nor any prerequisites or exclusions. The only supplemental sentence is a quirk note, not guidance on tool selection.

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