CreateHostGroup

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 says 'operation' and gives no information about side effects, permissions, resource creation, or any impact on LTS configuration. The name implies creation, but the description itself adds no 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 sentence but is under-specified rather than concise. It contains no useful information beyond the tool name and product domain, so the brevity is not serving a purpose.

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?

This is a create operation with a nested body schema, no output schema, and no annotations. The description fails to provide essential context such as what the tool creates, required fields, or any operational effects, making it inadequate for an agent to select and invoke the tool correctly.

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 description provides no parameter explanations. The schema has 3 top-level parameters, with only region and project_id having descriptions ('Overrides HUAWEI_REGION' / 'Overrides HUAWEI_PROJECT_ID'). The body parameter and its nested properties like host_group_name and host_group_type are completely unexplained, and the description does not compensate for this gap.

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 'Huawei Cloud LTS operation CreateHostGroup' merely restates the tool name and provides only a vague domain context. It does not state what creating a host group does, what a host group is, or how it differs from sibling tools like UpdateHostGroup or ListHostGroup.

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 use this tool versus alternatives. Sibling tools such as DeleteHostGroup, UpdateHostGroup, and ListHostGroup exist, but the description does not mention them or provide any decision context.

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