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

No annotations are provided, so the description carries the full burden. It implies a read/lookup operation but never states that it is read-only, what the response contains, whether results are paginated, or whether EU-wide obligations are merged with country ones (only implied by "inkl.").

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?

Extremely compact and front-loaded: the resource is stated first, then the parameter examples. Every fragment earns its place, though the telegraphic style and missing verb cost a bit of clarity.

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, no output schema, and 0% schema coverage, the description should explain what comes back (a list of obligations?) and confirm read-only behavior. It leaves the return shape entirely unspecified and covers only one of two parameters in depth.

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 0%, so the description must compensate. It does meaningful work for taetigkeit by enumerating valid values (website, online_handel, rechnung, werbung, ki_kontakt, gruendung) and explaining the empty default ("leer = alle"). It only partially covers land, giving example values DE/LU without stating whether other codes are accepted.

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?

"Pflichten für ein Land (DE, LU) inkl. EU-weiter Pflichten" names the resource (compliance obligations) and its scope (per-country plus EU-wide), so an agent can infer it's a lookup. However, there is no verb (get/list/retrieve) and no explicit statement distinguishing it from the sibling *_pruefen tools, which check things rather than list obligations.

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?

No when-to-use or when-not-to-use guidance and no mention of alternatives among the siblings (ki_hinweis, rechnung_vorpruefen, vat_pruefen, werbung_vorpruefen). The only usage hint is the parameter-level "leer = alle", which is about invocation, not tool selection.

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