qdii_a_index_jsl

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

Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and destructiveHint, covering the safety profile. The description adds the source URL and return type but does not disclose additional behavior such as data volume, columns, or potential pagination.

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 very short, but it consists of fragments rather than complete sentences and repeats the category 'T+0 QDII-亚洲市场-亚洲指数' twice. There is some redundancy, though it is not verbose.

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 no output schema, the description should explain what data the DataFrame contains, but it only gives a category name. The agent cannot infer the columns, row structure, or how to interpret the returned data, making the tool insufficiently specified for a simple data-listing tool.

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 only parameter 'cookie' has no description in the schema, and the description does not mention it at all. With 0% schema coverage, the agent has no clue what the cookie parameter is for or when to provide 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 identifies a specific resource (T+0 QDII-Asia Market-Asia Index) and its source (Jisilu URL), and states the return type (pandas.DataFrame). This clearly differentiates it from siblings like qdii_e_index_jsl and qdii_e_comm_jsl, though it lacks an explicit verb like 'fetch'.

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. There is no mention of exclusions, prerequisites, or scenarios where other QDII tools would be more appropriate.

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