futures_settle_ine

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

Annotations already declare readOnlyHint=true and idempotentHint=true, so safety is covered. The description adds valuable behavioral context: accepted date formats (YYYY-MM-DD, YYYYMMDD, datetime.date), default to current trading day, and return type pandas.DataFrame. This goes beyond what annotations provide and clarifies expected input flexibility.

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 uses a compact docstring style with a title line, source URL, and parameter/return documentation. It is not excessively verbose and each part is informative. The title line is slightly redundant with the tool name but serves as a clear subject statement, and the structure is logically organized.

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?

For a simple one-parameter data retrieval tool, the description provides adequate context: the source URL, parameter semantics, default behavior, and output type. However, it does not describe the contents of the returned DataFrame (e.g., columns or meaning of settlement parameters), which could be useful for agents. Given the low complexity, it is mostly complete.

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 sole parameter 'date' is thoroughly documented in the description with format options, default behavior, and accepted types. This fully compensates for the 0% schema description coverage and provides clear guidance for constructing valid inputs. The description also specifies the return type, adding further semantic value.

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 begins with the Chinese title '上海国际能源交易中心-结算参数' which identifies the resource (Shanghai INE settlement parameters) but lacks an explicit verb like 'retrieve' or 'get'. It is more of a label than a functional statement, though the URL and parameter docs add some clarity. It does not explicitly distinguish from sibling tools like futures_settle_shfe or futures_settle_cffex beyond the name itself.

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. It does not mention that this is specific to the INE or compare with other futures_settle_* siblings. There are no preconditions, exclusions, or examples of appropriate use cases.

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