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

No annotations are provided, so the description carries the behavioral transparency burden. It does disclose the core behavior: it returns a tour page URL and a contact path, and the 'Liefert' verb implies a read-only retrieval operation. It does not cover failure modes, validation, or the exact nature of the contact route, but for a simple retrieval tool it is adequate.

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 a single concise sentence that front-loads the main deliverable (the correct tour page URL) before mentioning the secondary contact path. There is no filler or redundant content.

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 one-parameter retrieval tool, the description covers the core purpose and output reasonably well. However, with no annotations, no output schema, and no explicit parameter explanation, the id parameter is left implicit and sibling differentiation is not directly addressed. It is minimally viable but has clear gaps.

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 schema has one required 'id' string parameter with 0% schema description coverage, and the tool description never directly explains that 'id' is the tour ID. The phrase 'zu einer konkreten Tour' indirectly implies the id identifies a tour, but the parameter semantics remain under-specified.

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 uses a specific verb ('Liefert') and names the exact resources: the correct tour page URL and a general contact route for the next steps of an inquiry. It is clearly distinct from sibling tools such as search_touren, get_tour_details, get_termine_preise, and compare_touren.

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?

The description provides a clear usage context: the tool is meant for the next steps or inquiry stage for a specific tour, which helps an agent select it over search or comparison tools. However, it does not explicitly name alternatives or state when not to use it.

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