UpdateSwitch

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

With no annotations, the description carries the full burden of disclosing behavior, but it reveals none. It does not state whether the operation is mutating, what effects it has, whether it can be reverted, or what inputs are needed beyond the schema.

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 sentence, which is concise, but it is under-specified rather than informative. It wastes the opportunity to convey meaningful information, making the brevity detrimental rather than helpful.

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 has no output schema and no annotations, the description is the only source of context. It fails to explain what the operation does, how it works, or what results to expect, leaving the agent completely in the dark.

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 covers 67% of parameters (region and project_id have descriptions), but the tool description adds no semantic meaning. The key parameter 'log_converge_switch' is left completely undocumented, and the description does not explain how the parameters relate to the operation.

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 UpdateSwitch' merely restates the tool name and provides no action or resource context. It does not specify what the switch does, what it updates, or how it differs from 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?

No guidance is given about when to use this tool versus the many sibling update tools (e.g., UpdateLogGroup, UpdateAccessConfig). There is no mention of prerequisites, contexts, or scenarios for which this operation is appropriate.

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