fund_individual_detail_info_xq

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false. The description adds that the return is a pandas.DataFrame and includes the source URL, but does not disclose additional behavioral traits such as rate limits, authentication needs, or specifics about what the trading rules data contains. Since annotations cover the safety profile, this is adequate but not rich.

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 reasonably concise but structured as a docstring with a bare sample URL (https://danjuanfunds.com/djapi/fund/detail/675091) that is not explained. It would be improved by front-loading a clear purpose statement rather than leading with the title and URL. No unnecessary fluff, but the structure is somewhat mechanical.

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?

The description states the return type and source, which is useful, but it does not describe the content of the trading rules, which fund codes are supported, or any edge cases. With no output schema and many sibling fund tools, a bit more context would help, but the tool is simple and annotations cover safety.

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%, but the description provides docstrings for both parameters: symbol is '基金代码' (fund code) and timeout is described as 'choice of None or a positive float number'. This adds meaning beyond the raw schema, especially for symbol. The timeout semantics are minimal but still more than the schema provides.

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 clearly indicates the tool retrieves trading rules (交易规则) for a fund, with the title '雪球基金-交易规则' and the return type. It distinguishes among sibling fund_individual_*_xq tools by focusing on trading rules rather than basic info or holdings. However, it lacks an explicit verb like 'get' or 'query'.

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 provides no guidance on when to use this tool versus alternatives. It does not mention sibling tools like fund_individual_basic_info_xq or fund_individual_detail_hold_xq, nor any exclusions or prerequisites. The only context is a bare sample URL.

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