macro_usa_business_inventories

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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the safety profile is covered. The description usefully adds the data range and the return type (pandas.DataFrame), but discloses nothing about update cadence or freshness beyond the range.

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?

Compact and front-loaded: the report subject and range come first, followed by a source link and return type. The :return:/:rtype: lines are slightly boilerplate but not wasteful since no output schema exists.

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 parameterless single-report tool with no output schema, the description covers subject, temporal scope, and return type, which is sufficient to call it correctly. Update frequency is the only notable omission.

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?

With zero parameters, the schema is trivially complete and the baseline is 4. The description adds the meaningful constraint that the data spans 19920301 to present, which is the only semantic detail a caller needs.

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 a specific resource (US business inventories monthly report) and its temporal scope (19920301-present), which clearly distinguishes it from the many other macro_usa_* siblings. It lacks an explicit retrieval verb, but the report naming is concrete enough for selection.

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 when-to-use guidance, no prerequisites, and no reference to alternative macro tools. The description says what the data is but not when an agent should call this versus another report.

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