UpdateLogStream

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

No annotations are provided, and the description contains zero behavioral information. It does not mention the effect of the update, potential risks, prerequisites, or permissions, leaving the agent entirely uninformed.

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 it is under-specified rather than concise. The single sentence adds no useful information and fails to earn its place.

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 5 parameters, a nested body, no output schema, and no annotations, the description is wholly inadequate. An agent cannot infer the semantics, required inputs, or potential side effects of this operation.

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 40%, and the description does not compensate. The schema defines parameters like body, log_group_id, and log_stream_id without explanation, and the description adds no meaning to any of them.

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 UpdateLogStream' merely restates the tool name with the generic word 'operation'. It lacks a specific verb and resource description, and does not distinguish this tool from sibling tools like UpdateLogGroup or UpdateAccessConfig.

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 or when to choose an alternative. Given the large set of sibling tools, the description provides no context for selecting this operation.

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