list_screener_metrics

List all available screener metrics and their Chinese names for CN, HK, US markets. Filter by keyword to confirm correct metric spelling before running screen_stocks.

Instructions

列出选股器支持的全部指标及其中文名(雪球官方元数据)。

在使用 screen_stocks 前调用,以确认指标名的正确写法。 建议总是带上 keyword:不带时会列出全部指标,返回内容大约是带 keyword 时的 9 倍。

Args: market: CN / HK / US keyword: 按中文名或指标名过滤,如「市盈」「roe」。省略则返回全部指标

Behavior3/5

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

描述披露了无 keyword 时返回内容约为带 keyword 时的 9 倍,提示性能影响。但没有提及返回结构、分页或数据量上限。无注释信息,描述承担部分行为披露责任,但本工具为只读元数据列表,风险较低。没有与注释矛盾。

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

描述简洁,先说明用途和调用时机,再用建议强调 keyword 的重要性,最后列出参数含义。没有冗余信息,但参数部分重复了 schema 中的字段名(可接受)。结构合理,重点前置。

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

有输出 schema(未展示但存在),描述解释了工具用途、参数含义和使用建议。对于列出元数据的工具,已足够让代理正确调用。缺少对返回格式的显式说明,但输出 schema 已提供,因此不算关键缺失。整体完整。

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

schema 描述覆盖率为 0%,但描述对两个参数给出了明确含义:market 指定市场(CN/HK/US),keyword 用于按中文名或指标名过滤。描述补充了 schema 未提供的信息,但未说明 market 的枚举或默认值的具体行为,虽有默认值但未描述。覆盖了关键语义,略有不足。

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

明确说明该工具列出选股器支持的指标及其中文名(雪球官方元数据),并提及在 screen_stocks 前调用以确认指标名。动词+资源+具体内容都清晰,与兄弟工具区分度高(screen_stocks 执行筛选,此工具提供元数据)。

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

明确说明应在 screen_stocks 前调用,且建议总是带 keyword 以避免返回大量数据。虽未明确提及何时不用,但上下文已提供足够的使用时机。与兄弟工具的关系通过引用 screen_stocks 暗示。

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