CreateConsumerGroup

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 does not state that this is a mutating operation, what side effects it has, whether it requires prior resources, error conditions, or permissions. The agent has no insight into the operation's behavior beyond the name.

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 short sentence, but it is under-specification rather than conciseness. It omits all substantive content, making it ineffective despite its brevity.

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 creation tool with 5 parameters, a nested body, no output schema, and no annotations. The description fails to explain the operation's purpose, parameter semantics, side effects, or expected return value, making it completely inadequate for an agent to invoke it 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?

Schema description coverage is only 40% (region and project_id have minimal overrides). The description adds no parameter context whatsoever. The nested body properties (timeout, create_time, consumer_group_name) are unexplained, and it is unclear how top-level group_id/stream_id relate to body log_group_id/log_stream_id.

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 is a tautology: 'Huawei Cloud LTS operation CreateConsumerGroup' merely restates the tool name without explaining what the operation does. It does not identify the resource (consumer group) or the action (creation) beyond the name, and it is indistinguishable from sibling tools like CreateLogGroup or CreateAccessConfig.

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?

No guidance is provided on when to use this tool versus alternatives. The description does not mention use cases, prerequisites, or the relationship to other resources such as log groups and log streams, nor does it exclude other options.

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