RegisterDmsKafkaInstance

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

No annotations are provided, so the description carries the full burden for behavioral disclosure. It discloses nothing about side effects, required permissions, or operational characteristics. The agent cannot know if this tool mutates state, creates resources, or is safe to invoke.

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 short sentence, but conciseness is not the same as under-specification. This text provides almost no useful content, so the brevity is not a virtue. It is closer to a placeholder than a carefully crafted concise 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?

With no annotations, no output schema, a nested body object, and no behavioral context, the description is completely inadequate. An agent would have no idea what this tool does, what inputs mean, what results to expect, or what side effects may occur.

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 input schema includes a 'body' object with kafka_name, instance_id, and connect_info, but the description provides no explanation of these or how they relate. Although region and project_id have descriptions in the schema, the crucial body parameter is untouched. The description adds zero semantic information beyond what the bare field names imply.

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 RegisterDmsKafkaInstance' merely restates the tool name and adds a generic platform prefix. It does not specify what 'RegisterDmsKafkaInstance' does, what resource it acts on, or how it differs from any of 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?

There is no guidance on when to use this tool vs alternatives. The description provides no context, prerequisites, or conditions under which an agent should select this tool over similar LTS operations.

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