qdii_e_index_jsl

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

The description adds that the return type is pandas.DataFrame, which is useful behavioral information. However, the return description ('T+0 QDII-亚洲市场') is misleading and contradicts the title, and no other behavioral traits (e.g., cookie usage, data freshness) are disclosed. With annotations already covering read-only/idempotent hints, the misleading return line prevents a higher score.

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 short but poorly structured: it starts with a title, then a URL, then a mislabeled return line that appears to be a copy-paste error. The information is not presented in a logical order, and the erroneous return statement wastes space and creates confusion.

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?

This is a simple tool with one optional parameter and no output schema, so the description carries a moderate burden. It fails to explain the cookie parameter, clarify the market focus, or reconcile the contradictory return line. The missing details on the cookie and correct return value make it incomplete for an agent to invoke correctly.

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?

The input schema has an optional 'cookie' parameter with zero description coverage. The description does not mention the cookie parameter at all, nor any other parameter details, so the agent cannot understand how or why to use it.

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 names the resource clearly (集思录-T+0 QDII-欧美市场-欧美指数) and includes a source URL, indicating it fetches European/American QDII index data from Jisilu. However, it lacks an explicit verb like 'get' or 'retrieve', and the return line says 'T+0 QDII-亚洲市场' (Asian market), which contradicts the stated European/American focus and confuses the actual purpose.

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 (e.g., qdii_a_index_jsl or qdii_e_comm_jsl). There are no prerequisites, examples, or exclusions mentioned, leaving the agent without context for selecting this tool.

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