macro_usa_current_account

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

Annotations already declare readOnly, idempotent, and non-destructive behavior, so the description only adds minor context: the data range, a source URL, and the DataFrame return type. This is useful but does not disclose deeper behavior like units, frequency, or column structure.

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 and front-loaded with the core meaning, followed by a source URL and return type. Some redundancy exists ('美国经常帐报告' appears multiple times), but the overall structure is efficient and scannable.

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 only says the return is a DataFrame containing the current account report. It lacks details about columns, units, release schedule, or how the data is structured, which would help an agent use the result effectively. It is adequate for a simple zero-parameter tool but not rich.

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 takes zero parameters, so the input schema is trivially complete. The description adds no parameter details, but none are needed. The baseline of 4 applies because there are no parameters to document.

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 the tool as a US current account report with a data range, clearly distinguishing it from sibling macro tools like macro_usa_trade_balance or macro_euro_current_account_mom. Though no explicit verb like 'get' or 'fetch' is used, the resource and scope are unambiguous.

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?

The intended usage is implied by the name and title (retrieve US current account data), but there is no explicit guidance on when to choose this tool over alternatives. It does not state exclusions or provide comparative context among the many macro_* siblings.

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