CreateLogStream

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. However, it reveals nothing about side effects, required permissions, idempotency, or error behavior. For a creation operation, an agent needs to know what gets created, any constraints, and what happens on conflict, none of which are mentioned.

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 conciseness. The single sentence merely repeats the tool name and adds a generic cloud context ('Huawei Cloud LTS operation'), so it does not earn its place. It lacks any substantive content that would justify its brevity.

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?

Given the tool's complexity (nested objects, no output schema, no annotations), the description is entirely inadequate. It must explain what the operation does, what the body parameter expects, and how log_group_id relates to the creation, but it provides none of this. The agent is left with only an opaque name and partial 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 50%, with only region and project_id having descriptions ('Overrides HUAWEI_REGION', etc.). The description text adds no parameter information at all, leaving body and log_group_id almost entirely unexplained. The description fails to compensate for the missing schema documentation, providing zero added meaning beyond the schema.

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 CreateLogStream' merely restates the tool name and cloud provider without stating what the operation does, what resource it acts on, or what effect it has. It provides no specific verb or resource beyond the name itself, so an agent cannot determine the tool's purpose.

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 does not mention any conditions, prerequisites, or comparisons to sibling tools like CreateLogGroup or ListLogStreams. The agent receives no help in deciding between this and other LTS operations.

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