CreateTags

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It does not mention side effects (e.g., creating or modifying resources), required permissions, or any other behavioral traits. The phrase 'operation' adds nothing about what actually happens, leaving the agent unaware of the tool's mutating nature.

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 this is under-specification rather than concise clarity. Every word merely restates the name and service context, contributing no useful information. While it is front-loaded, it does not earn its place as a functional 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?

The tool has 5 parameters, a nested object, and no output schema, making it moderately complex. Yet the description offers no information about input requirements, return values, or operational context. It is completely inadequate for guiding an agent to 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?

Schema description coverage is only 40%, and the description offers no parameter explanations beyond the shorthand 'Overrides HUAWEI_REGION' etc. The nested 'body' object, 'resource_id', and 'resource_type' are left undocumented. The description adds no meaning to the parameters, failing to compensate for the low schema coverage.

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 CreateTags' essentially restates the tool name and title. It provides minimal context (the cloud service) but fails to specify what the operation actually does, such as which resource tags are created on or how tags are applied. This is close to a tautology.

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 given about when to use CreateTags versus the many similar sibling tools (e.g., CreateLogGroup, CreateLogStream, CreateAccessConfig). There are no stated use cases, prerequisites, or alternative suggestions. The description leaves the agent without any direction on tool selection.

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