Read-only

Calculate Average True Range (ATR) from Binance K-line data to measure volatility, using Wilder smoothing for stable indicator values.

Instructions

直连版：拉取 K 线后计算 ATR，返回稳定序列（衡量波动，默认 Wilder 平滑）。

  3. First observedv2.0.2

TDQS

A4/5.0
Behavior4/5

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

除注解readOnlyHint已经说明只读外，描述额外说明了计算过程（拉取K线、计算ATR）、默认平滑方式（Wilder）和返回特性（稳定序列），这补充了注解之外的实际执行行为。没有与注解矛盾。

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

Conciseness5/5

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

描述仅用一句话就包含了类型、计算方式、结果特性和默认参数，语义紧凑，前置了对“直连版”的限定，没有任何冗余。

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

Completeness3/5

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

在已有输出schema和只读注解的加持下，描述基本覆盖了核心调用背景，但“直连版”的设定没有上下文说明，也没有提及与潜在非直连版或交易类工具的边界。对于多工具开放环境，仍有模糊空间，尚算刚刚及格。

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

Parameters2/5

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

当前参数有4个，schema描述覆盖率为0%，描述中几乎没有对参数进行额外解释。只通过“默认Wilder平滑”间接暗示了period的默认风格，但symbol、interval、limit等参数均未在描述中说明对应语义或使用建议，描述未帮助填充schema空白。

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?

明确说明直接获取K线后计算ATR，并指出其为波动率工具，同时提到默认Wilder平滑。与其他指标工具（SMA/EMA/MACD等）在功能上有明显区分，动词和资源明确。

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?

描述中通过“衡量波动”点明了使用场景，且在指标类工具中能自然引导Agent在需要波动率时选择该工具。但未明说何时不应使用或与其他波动率工具的取舍，缺少明确的排除性指引。

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