UpdateStructConfig

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

There are no annotations, and the description carries the full burden of behavioral disclosure. It fails to mention whether the operation mutates state, what resources are affected, whether permissions are required, whether it is idempotent, or what side effects may occur.

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 short, but brevity is not conciseness when no information is conveyed. It is a tautological restatement of the tool name and fails the requirement that every sentence 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?

For a tool with no annotations, no output schema, and a complex nested body parameter, this description is completely inadequate. It leaves the agent without any understanding of the operation's purpose, behavior, parameters, or return value, making correct invocation essentially impossible.

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 schema documents region and project_id as overrides, but the nested body object and its five properties are completely unexplained. The description adds no parameter meaning, and the body fields like template_id, log_group_id, and template_type are ambiguous without further context.

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 UpdateStructConfig' merely restates the tool name without explaining what the operation does. It does not specify a verb plus resource, nor does it distinguish this from closely named siblings like UpdateStructTemplate, CreateStructConfig, or ShowStructTemplate.

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 the many sibling tools. There is no mention of intended scenarios, prerequisites, or alternatives, leaving the agent without any basis for selection.

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