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

Annotations already declare readOnlyHint, idempotentHint, non-destructive and openWorld=false=false, so the safety profile is covered. The description adds that only upcoming dates ('Nächste') are returned with their application deadlines, but it says nothing about the shape of each result (e.g. Land, Termin, Frist), which would be the valuable extra context here.

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?

A single front-loaded sentence with zero filler; the resource, the pairing with deadlines, and the scope are all stated before any parameter detail. Nothing repeats the title or annotations unnecessarily.

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 low-complexity, read-only, two-optional-parameter tool with full schema coverage and rich annotations, the description is sufficient to call it correctly. The only minor gap is the absence of any hint about the returned entry structure, which matters slightly given there is no output schema.

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%, so both 'ab' and 'land' are already documented with format, examples and defaults. The description reinforces the 'alle 16' behavior of 'land' but adds no syntax or format detail beyond the schema, matching the baseline for full-coverage schemas.

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 — upcoming Einstellungstermine for the Referendariat together with their Bewerbungsfristen — and states the scope (one Bundesland or all 16). It does not name a sibling, but no sibling tool overlaps in topic, so an agent can still select it unambiguously.

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?

It gives clear context for the two usage modes ('für ein Bundesland oder alle 16'), which maps directly onto the optional 'land' parameter. There are no explicit exclusions, but none are needed since the sibling tools address unrelated topics.

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