CreateLogGroup

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

With no annotations provided, the description carries the full burden of disclosing behavioral traits like side effects, required permissions, or idempotency. The description provides none of this, giving no indication of what happens when the tool is invoked or what the consequences are.

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 extremely short, but this is under-specification rather than conciseness. It contains a single vague clause that provides no useful information, failing to earn its place by not conveying any actionable content.

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?

Given the tool has 4 parameters, nested objects, no output schema, and no annotations, the description is completely inadequate. It does not help the agent understand how to invoke the tool, what inputs are needed, or what to expect as a result. This is a critical gap for a create operation.

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 adds no meaning to any parameter. The schema covers only 50% of parameters with descriptions (region and project_id), leaving the body fields (ttl_in_days, log_group_name, etc.) undocumented. The description does not compensate, so the agent has no semantic understanding of what values to supply.

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 CreateLogGroup' is essentially a tautology—it restates the tool name without specifying what the operation does. It adds only the service context (Huawei Cloud LTS) but no actual verb or resource behavior, making it indistinguishable from a generic operation declaration.

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 any alternative. No mention of prerequisites, typical scenarios, or exclusions. The description simply states it is an operation, leaving the agent to infer usage entirely from the tool name.

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