ListLogStream

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

With no annotations provided, the description must disclose behavioral traits, but it offers none. There is no indication of read-only/write behavior, whether the operation supports pagination, what the return format is, or any side effects. The agent has zero insight into the tool's runtime behavior.

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 short, but it is under-specified rather than concise. The single sentence is a waste because it repeats the tool name without adding information. True conciseness would pack meaningful content into few words; this fails to do so.

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 tool with 3 parameters, no output schema, and no annotations, the description is completely inadequate. It should cover basic purpose, when to use it, and how parameters affect the operation. Instead, it provides nothing beyond the name, leaving the agent unable to select or 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?

The schema provides descriptions for region and project_id ('Overrides HUAWEI_REGION' and 'Overrides HUAWEI_PROJECT_ID'), but log_group_id has no description. The tool description adds no parameter semantics and does not clarify how log_group_id relates to the listing operation. Since schema coverage is only 67% and the description is silent, parameter meaning remains unclear.

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 a tautology: 'Huawei Cloud LTS operation ListLogStream' merely restates the tool name without specifying what the operation does. It fails to identify the resource (log streams) or the action (list) beyond the name itself. The existence of a sibling tool 'ListLogStreams' makes this even more confusing, as the singular/plural distinction is not explained.

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 versus alternatives. The description provides no context about the intended use case, such as listing log streams under a specific log group, nor does it mention any exclusions or alternatives among the numerous sibling tools.

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