variotrip route eSIM configurator

Shop facts

get_shop_facts

Read-onlyIdempotent

What variotrip is and how it works, in the shop’s own words: one mobile-data eSIM for the whole route, one shared data pool, the trip length, ranges, delivery, payment, hotspot, activation, top-ups (data, days or a country), router activation, e-mails, support. Use for any question that is not a price.

Tool call template

This tool declares no required parameters. Add optional parameters from the input schema as needed.

Input Schema

Name	Required	Description	Default
`bucket`	No	Optional language-region bucket the customer shops in, e.g. en-gb, de-de (sets currency and link locale). Defaults from language.
`language`	No	ISO language of the conversation, e.g. en, de, ja. Localizes country names and sets the language/currency of links and prices.

Behavior4/5

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

Annotations already declare readOnly, idempotent, non-destructive and closed-world, so safety is covered. The description adds genuine behavioral context — that content is returned 'in the shop's own words' and precisely which topics are included — which tells the agent what kind of answer to expect and that it is authoritative shop copy rather than computed output.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The scoping statement is front-loaded before the topic list, and every clause earns its place by naming a covered subject. The single long enumerated sentence is dense but readable; a short structural break before the usage rule would improve scanning.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a two-optional-parameter read tool with no output schema, the description is nearly complete: the agent knows what to ask it for and what it will not cover. The one remaining gap is the return shape — whether facts come back as prose paragraphs or keyed fields — which would help an agent consume the result.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so bucket and language are already fully documented, including their currency/locale effects. The description adds nothing about either parameter, which is acceptable at baseline but no better.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific resource (variotrip's own-words shop facts) and enumerates exactly what is covered — data pool, trip length, delivery, payment, hotspot, activation, top-ups, support. That enumeration lets an agent distinguish it from price_grid and quote_route without opening any schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The closing clause 'Use for any question that is not a price' gives a clear positive rule plus an exclusion, routing non-pricing intent here and pricing intent to the price siblings. It never names a sibling tool explicitly, so the routing is inferred rather than spelled out.

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