extract_chinese_page_tool

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

Discloses key behavior of removing ads and navigation interference. With no annotations provided, the description fulfills transparency for a read-like operation, though it could mention if any authentication is needed.

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?

Two sentences efficiently convey purpose, suitable sites, and behavior. No redundant information.

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?

Description covers what the tool does, for which sites, and what it removes. With an output schema present, lack of return value details is acceptable. Could mention that results are in Chinese.

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 description coverage is 0%, and the description only mentions URLs should be from Chinese web pages, but does not add constraints like required format, encoding, or examples for the 'url' parameter.

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?

Description clearly states the tool extracts main text from Chinese web pages, with specific examples (Zhihu, Bilibili, 36kr, CSDN) that distinguish it from search-focused siblings like baidu_search_tool and bilibili_search_tool.

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?

Explicitly states it is 'suitable for reading' content from Chinese websites, indicating when to use. While it doesn't specify when not to use, the context of siblings suggests it's for extraction rather than searching.

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