list_blacklist

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

注解已提供 readOnlyHint=true、idempotentHint=true、destructiveHint=false，安全性信息充足。描述额外说明了“分页”这一行为特征，但没有进一步披露分页方式、游标含义或默认页大小等细节，属于中等补充。

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?

描述只有一句话，直接点出核心功能和分页特性，没有任何冗余内容。信息位置靠前，简洁且易于解析。

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?

工具本身较为简单，注解和输出 schema 已覆盖大部分安全性和返回结构。但描述缺少对 next_openid 分页语义的明确说明，也没有提供与兄弟工具的选择依据，整体上可用但仍有明显信息缺口。

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 对参数 next_openid 的描述覆盖率为 0%，描述仅通过“分页”间接暗示该参数与分页有关，但没有说明 next_openid 是下一页游标、首次请求应留空或如何使用返回值中的下一页标记。对于低覆盖率的 schema，描述未能充分补偿。

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?

描述使用了明确的动词“获取”和资源“公众号黑名单”，并限定为“分页”方式，清晰表达了工具功能。与兄弟工具如 blacklist_users、unblacklist_users（操作用户黑名单状态）和 list_users（获取用户列表）能明显区分。

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?

描述隐含了“查看黑名单列表时使用”的用法，但没有明确说明何时应使用此工具而非 list_users 或 blacklist_users，也没有提到分页游标的使用条件或替代方案。属于可推断但未明示的用法指导。

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