Changes observed during successful MCP inspections.
v0.1.0Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
注解已提供readOnlyHint和idempotentHint等安全特性，描述补充了'缺字段会明确提示'的行为信息，增加了价值。但未详细说明计算规则或边界情况，且与注解无矛盾。
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?
描述为一句紧凑的句子，直接说明核心操作并附有错误处理说明，无冗余内容，但稍微长了一点，可以更精简。
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?
无输出模式，描述未说明返回值或输出格式。对于简单计算工具，应至少提及结果形式，但描述仅说会提示缺字段，不够完整。
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?
模式覆盖率为0%，描述完全未提及report_id参数的含义或用法。描述只提及'报表'，但未说明该参数如何标识报表，未补偿模式中的缺失。
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?
描述明确说明了计算贡献利润的动作，并列出具体数据来源（收入、成本、物流、平台费、广告费、退款），区别于其他获取指标的工具。但未明确提及与兄弟工具的差异，例如与product_metrics_get的区别，因此未达到满分。
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?
描述仅隐含地表明用于利润计算，未提供显式的使用时机或排除条件，也未提及替代工具。缺少'当使用此工具时'或'在何种情况下不使用'的指导。
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
