ListActiveOrHistoryAlarms

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 state that this is a read-only listing operation, does not mention pagination, ordering, filtering, or any side effects. The name implies 'list' but the description itself is silent.

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 brief, but this is under-specification, not conciseness. It is a fragment that fails to convey necessary information, earning no place in a well-structured description.

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 complex tool with 7 parameters, nested objects, and no output schema or annotations. The description is a single phrase that provides almost no context, making it completely 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?

Schema description coverage is only 29% (only region and project_id have descriptions). The description does not compensate by explaining any of the 7 parameters or nested objects. It adds zero value beyond the schema.

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 ListActiveOrHistoryAlarms,' adds no information beyond the tool's name. It is a tautology: it merely restates the tool name with a generic 'operation' prefix. There is no verb, no resource, and no distinction from sibling tools.

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 zero guidance on when to use this tool versus the many sibling tools like ListKeywordsAlarmRules or ListSqlAlarmRules. No context, prerequisites, or exclusions are mentioned.

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