fund_overview_em

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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is clear. The description adds the return type (pandas.DataFrame) but does not disclose additional behavioral details like pagination, rate limits, or data granularity.

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 concise and organized as title, URL, param, and return. It front-loads the key information and avoids verbosity, though it is slightly sparse.

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?

With only one parameter and no output schema, the description provides the return type but does not explain what fields are included in the '基本概况' (basic overview). This is a gap for users expecting to know the DataFrame columns, but the tool is simple and self-descriptive from the name and URL.

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 defines the parameter as '基金代码' (fund code), which adds basic meaning. It does not elaborate on format, constraints, or examples beyond the default '015641' in the schema.

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 '天天基金-基金档案-基本概况' (Tiantian Fund - Fund Archive - Basic Overview) and provides a URL, clearly indicating it retrieves basic fund overview information. However, it does not distinguish this tool from many sibling fund tools (e.g., fund_info_ths, fund_individual_basic_info_xq) beyond the title.

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?

No guidance is provided on when to use this tool versus alternatives. The description only gives a parameter and return type, with no context about selecting this tool among the numerous fund-related siblings.

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