list_items

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

无注释，描述未披露行为特征，如是否只读、是否需要认证、返回格式等。仅提到分页，但对副作用和前提条件无任何说明。

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?

描述极简，一句完成，但牺牲了关键信息。可以适当扩展而不破坏简洁性，因此评为中等。

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?

6个参数、无输出模式、无注释，描述仅覆盖版本要求和分页概念，未能提供调用该工具所需的完整上下文，如返回格式、错误处理、认证要求等。

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?

模式描述覆盖率仅33%（page和size有描述），描述未额外解释必需参数（appId、env、clusterName、namespaceName），导致参数语义严重不足。

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?

描述明确说明工具用于分页获取Namespace下的配置项，动词和资源清晰。但未与兄弟工具如'get_item'或'list_namespaces'进行区分，因此略降一分。

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?

描述仅包含版本要求，未提供何时使用此工具而非兄弟工具（如'get_item'获取单个项）的指导，也未说明不适用场景。

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