macro_china_insurance_income

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

The annotations already declare this as read-only, idempotent, and non-destructive, so the description has a lower burden. It adds a source URL and states the return type (pandas.DataFrame), but provides no additional behavioral context such as data coverage, frequency, or update schedule.

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 and includes a useful source URL. However, it repeats the term '原保险保费收入' three times (in title, description, and docstring), which is slightly redundant but 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?

For a no-parameter macro data tool, the description gives the source URL and return type, which is a reasonable starting point. However, it does not specify the DataFrame's columns, time range, units, or whether it is historical or current, leaving some gaps for an agent.

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 tool has zero parameters, and the schema is fully covered. With no parameters to document, the description is not expected to add parameter details, and any additional info would be optional.

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 identifies the resource: China original insurance premium income, and provides a source URL. While it lacks an explicit verb like 'fetch' or 'list', the intent is unambiguous. It does not explicitly differentiate itself from the sibling macro_china_insurance, but its specificity is clear.

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?

There is no guidance on when to use this tool versus alternatives. It does not mention context, exclusions, or comparisons with sibling macro tools, leaving the agent to infer usage from the name alone.

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