获取股票/加密货币相关新闻

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

No annotations are provided. The description only states the basic function and does not disclose behavioral traits such as data source, freshness, rate limits, or whether it supports multiple markets. As the sole source of behavioral info, it is insufficient.

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?

The description is a single sentence with no wasted words, efficiently conveying the tool's purpose. It is front-loaded and appropriately sized.

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?

Given the tool's simplicity (2 params, no output schema), the description is minimal but adequate. However, it lacks specification of the news source or geographical scope, which is relevant given sibling tools named 'stock_news_global' and 'stock_news_us'. Some context is missing for full usability.

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 coverage is 100% as both parameters have descriptions. The description adds the word '近期' (recent) implying a time filter but no additional semantics beyond the schema. Baseline 3 is appropriate since the schema already covers parameter meaning.

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?

The description states the verb '获取' (get) and resource '近期相关新闻' (recent related news), with input '股票代码或加密货币符号' (stock code or cryptocurrency symbol). It is clear but does not differentiate from sibling tools 'stock_news_global' and 'stock_news_us' which may have different geographic or type scopes.

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?

The description indicates when to use (get news by symbol) but provides no guidance on when not to use it or alternatives. With many sibling news tools, the lack of differentiation or exclusion criteria is a significant gap.

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