get_datev_export

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It says 'preview or download' but does not clarify what each implies (e.g., whether download triggers file generation, whether it is read-only, or any side effects). This remains ambiguous.

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?

One concise, front-loaded sentence with no filler. Every word contributes to the tool's purpose, achieving high clarity with minimal length.

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 annotations or output schema, the description fails to explain the difference between preview and download, the data format returned, or any constraints on year/month. While the tool is simple, the description leaves critical context unresolved.

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?

Schema description coverage is 100% with clear definitions for 'year' and 'month'. The description adds no additional parameter meaning, but the baseline of 3 is appropriate since the schema sufficiently documents both parameters.

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?

Clearly states the tool retrieves DATEV export data for preview or download. The resource ('DATEV export data') and target ('tax advisor') are specific, and no sibling tool overlaps with this exact function.

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?

Implied usage: use when you need DATEV export data for a tax advisor. However, no explicit when/when-not guidance or alternatives are mentioned, so the agent must infer the tool's role from its name.

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