UpdateKeywordsAlarmRule

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 behavioral disclosure. The description discloses nothing about side effects, permissions, whether it is destructive, or what the operation actually changes. This is a significant gap for a mutation tool.

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 a single sentence, but it is under-specified rather than concise. It provides no actionable information. The brevity is not a virtue here; it fails to earn its place by adding any value.

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 a deep nested request body, no output schema, no annotations, and many sibling tools. The description is completely inadequate for an agent to understand what the tool does, when to invoke it, or how to construct parameters.

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 67%, but that coverage is only for trivial override parameters (region, project_id). The main 'body' parameter is a large nested object with dozens of undocumented properties. The description adds zero parameter semantics, failing to compensate for the schema's opaque structure.

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 UpdateKeywordsAlarmRule' is purely tautological. It restates the tool name and adds a generic 'operation' label, with no verb describing the action (e.g., 'Updates a keyword alarm rule') or the resource affected. It does not distinguish from the many 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?

No guidance is provided about when to use this tool versus alternatives. There is no mention of prerequisites, use cases, or exclusions. Users are left to infer from the name alone.

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