set_property

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

无annotations提供安全信息，描述也未披露任何行为细节。未说明属性设置是覆盖还是合并，未提及权限要求、错误处理或对现有属性的影响。仅提到可以设置任意x-component-props或x-decorator-props字段，这属于参数类别而不是行为。整体行为透明度过低。

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?

描述仅两句话，第一句点明核心功能，第二句提供关键参考信息。结构紧凑，无冗余内容，核心信息前置，符合优秀工具描述的标准。

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?

无输出schema，描述也未说明操作成功与否的反馈方式。但对于一个修改操作，可能不需要详细返回值。不过描述没有说明错误情况、权限要求或对现有属性的影响等上下文信息，参考Skill文件可能补充部分但描述本身不算完整。在无annotations的情况下描述应承担更多责任，因此给3分。

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?

虽然schema已覆盖100%参数，但描述额外解释了propType的含义（对应component/decorator）并指出属性名映射参考Skill文件，这为key参数提供了重要指导。相比schema中较为泛泛的描述，描述增加了参数语义的深度，具有明显增值。

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'修改已添加组件的属性'，准确指出了操作对象和动作。与'add_component'等新增类工具区分明显，但没有明确与'set_full_schema'等整体替换工具的区分。虽然提到了'已添加组件'，但没有明确说何时该用此工具而非其他修改工具，但目的清晰，故得4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?

描述没有提供任何使用时机或替代工具的指引。没有说明何时使用本工具而非其他修改工具（如set_full_schema），也没有说明前置条件（如必须先有组件存在）。仅隐含了'已添加组件'这一前提，但缺乏明确的when/when-not说明。

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