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

Annotations already declare readOnlyHint, idempotentHint, closed-world, and non-destructive, so the safety profile is fully covered. The description adds genuinely useful scope context for a zero-parameter tool — that coverage spans Bahn, Fernbus, Schiff, Pauschalreise (not just flights) and includes forward-looking reform content — telling the agent what the knowledge base does and does not contain.

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 dense sentence with no filler, front-loaded on 'Fristen' then enforcement routes then the reform. It earns its length by enumerating distinct coverage areas, though the nested parenthetical lists are slightly heavy to parse.

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 output schema and no parameters, the description must convey what comes back, and it does enumerate the topical contents well. It does not state the return format (structured list vs prose) or note the German/EU jurisdictional framing implied by LBA/EBA, which is a minor gap.

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?

There are zero parameters, so by rule the baseline is 4. No parameter semantics are needed and none are missing.

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 specific content: deadlines (limitation periods, application and reporting windows) across six transport/travel modes, enforcement routes (company, arbitration, LBA/EBA, EU small-claims), and the 2027 flight reform. That is clearly distinguishable from the calculate_* sibling tools and from search_legal_articles. It stops short of a clean verb+resource statement (the verb is only implicit in 'get'), hence a 4 rather than 5.

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 topical enumeration implies the use case (fetch an aggregated overview of deadlines and enforcement paths), but there is no explicit when-to-use guidance and no routing to alternatives among the four legal-reference siblings. An agent must infer that this is the broad overview while search_legal_articles serves narrow article lookups.

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