UpdateAlarmRuleStatus

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

No annotations are provided, so the description carries the full burden of disclosing behavior. It does not mention that this tool likely modifies an alarm rule's status, any side effects, required permissions, or potential errors. The description is behaviorally opaque.

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 brevity here is under-specification rather than conciseness. It contains only a restatement of the name and a vague 'operation' label. A well-structured description would front-load the purpose but still provide substantial guidance. This fails to convey any meaningful information.

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 a nested object parameter, no output schema, and no annotations, the description is grossly incomplete. It provides no context about expected inputs, behavior, or return values. An agent would be completely unable to craft a correct invocation based on this description alone.

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 description coverage is 67% (region and project_id have descriptions), but the description adds no parameter-level meaning. The 'body' parameter, which is an object with nested properties (type, status, alarm_rule_id), is completely undocumented. The description does not explain what these fields represent or how they relate to the tool's action.

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 UpdateAlarmRuleStatus.' It merely restates the tool name with a generic 'operation' label, offering no explanation of what the tool actually does (e.g., updating the status of an alarm rule). There is no specific verb or resource described beyond what is already in the name.

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?

The description provides no guidance on when to use this tool versus any alternative. It does not mention prerequisites, typical scenarios, or why one would choose this tool over sibling tools like UpdateKeywordsAlarmRule or UpdateSqlAlarmRule. There is no context to help an agent select it appropriately.

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