DeleteKeywordsAlarmRule

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 confirm that the tool deletes a resource, nor does it mention any side effects, irreversibility, permission requirements, or idempotency behavior. The description is even less informative than the update_drive example, which at least stated 'Update shared drive settings.' Here, the description merely names the operation without any behavioral detail.

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 effective conciseness. A concise description would use a clear verb and state the action, such as 'Deletes a keywords alarm rule in Huawei Cloud LTS.' Instead, it provides a fragment that restates the name, offering no structure or meaningful 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?

For a delete operation with three parameters and no output schema, the description is completely inadequate. It does not explain the effect of deletion, whether it is reversible, what happens on success/failure, or how the keywords_alarm_rule_id is used. The description lacks essential context needed to safely invoke the tool, especially given the absence of annotations and output schema.

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%, meaning region and project_id are partially documented, but keywords_alarm_rule_id has no description. The tool description adds nothing about any parameter, failing to compensate for the undocumented parameter. It does not explain what the parameters mean, how they relate, or provide any additional context beyond the schema. The description offers zero semantic value for parameters.

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 essentially a restatement of the tool name: 'Huawei Cloud LTS operation DeleteKeywordsAlarmRule.' It does not use a specific verb like 'deletes' or provide any functional explanation beyond what the name already conveys. It identifies the service context but fails to clearly state the tool's action, making it tautological rather than informative.

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 alternatives. It does not mention prerequisites, scenarios for deleting a keywords alarm rule, or differentiate it from sibling operations like UpdateKeywordsAlarmRule or DeleteSqlAlarmRule. There is no implied usage context beyond the name itself.

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