macro_germany_ifo

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

Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and destructiveHint=false. The description adds the return type (pandas.DataFrame) and source URL, which is some context, but it does not disclose any additional behavioral traits such as data range, freshness, or units. No contradiction with annotations is present.

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 three lines and compact, containing the title, source URL, and return type. It is not verbose and each line carries some information, though it is more of a metadata listing than a coherent prose description.

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?

Given there is no output schema, the description should explain the returned data. It minimally states that the return is the IFO index as a DataFrame, but lacks specifics about columns, frequency, or units. This is adequate for a simple zero-parameter fetch but leaves ambiguities.

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 input schema has zero parameters, so the baseline is 4. The description does not need to document parameters and it does not, which is appropriate.

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 is essentially a title and a URL, with a docstring-like :return: line. It restates the tool name 'macro_germany_ifo' as '德国-IFO商业景气指数' without an active verb or a clear explanatory sentence, making it closer to a tautology. It adds the source URL and return type, but the core purpose is simply a label.

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 the many sibling macro tools (e.g., macro_germany_cpi, macro_germany_gdp). It only provides a source URL and return type, so the agent gets no decision support or alternative exclusions.

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