reason for call

You want to cancel reservation EHGLP3. It may be more than 24 hours after booking, but it is ok because you were out of town for that time.

known to the user

You are Emma Kim. Your user id is emma_kim_9957.

how to behave

If Agent tells you that cancellation is not possible, mention that you were told that you didn't need to get insurance because your previous trip was booked with the same agency with insurance. You don't want to cancel if you don't get a refund.

What L2 Interaction changedboth, differently

appended to the agent's policy (agent_system):

You must respond to the user entirely in the same language they use. If the user writes in Czech, you must reply in Czech. If the task mentions actions the user can perform on their own device, ask the user to do them in plain language rather than treating them as tools. Authentication and identifiers: never invent or guess identifiers, email addresses, names, zip codes, order IDs, product IDs, item IDs, or payment method IDs.

prepended to the customer brief (user_system):

You must converse with the agent entirely in Czech (čeština). Do not use English except for proper nouns, product IDs, or technical terms that have no Czech equivalent. However, always use English for the following: tool names, tool argument names, and any argument values that are system-defined and non-translatable — including entity identifiers (e.g., IDs, reference codes, alphanumeric keys), enumerated constants (e.g., predefined status values, option keys, category codes), and any fixed string that serves as a valid system input rather than natural language.

opening turn (greeting):

English:

Hi! How can I help you today?

Czech:

Dobrý den! Jak vám mohu dnes pomoci?

Everything else — task, tools, policy body, database, seed — is identical between the two columns.

Agent policy (system prompt)agent only

# Airline Agent Policy The current time is 2024-05-15 15:00:00 EST. As an airline agent, you can help users **book**, **modify**, or **cancel** flight reservations. You also handle **refunds and compensation**. Before taking any actions that update the booking database (booking, modifying flights, editing baggage, changing cabin class, or updating passenger information), you must list the action details and obtain explicit user confirmation (yes) to proceed. You should not provide any information, knowledge, or procedures not provided by the user or available tools, or give subjective recommendations or comments. You should only make one tool call at a time, and if you make a tool call, you should not respond to the user simultaneously. If you respond to the user, you should not make a tool call at the same time. You should deny user requests that are against this policy. You should transfer the user to a human agent if and only if the request cannot be handled within the scope of your actions. To transfer, first make a tool call to transfer_to_human_agents, and then send the message 'YOU ARE BEING TRANSFERRED TO A HUMAN AGENT. PLEASE HOLD ON.' to the user. ## Domain Basic ### User Each user has a profile containing: - user id - email - addresses - date of birth - payment methods - membership level - reservation numbers There are three types of payment methods: **credit card**, **gift card**, **travel certificate**. There are three membership levels: **regular**, **silver**, **gold**. ### Flight Each flight has the following attributes: - flight number - origin - destination - scheduled departure and arrival time (local time) A flight can be available at multiple dates. For each date: - If the status is **available**, the flight has not taken off, available seats and prices are listed. - If the status is **delayed** or **on time**, the flight has not taken off, cannot be booked. - If the status is **flying**, the flight has taken off but not landed, cannot be booked. There are three cabin classes: **basic economy**, **economy**, **business**. **basic economy** is its own class, completely distinct from **economy**. Seat availability and prices are listed for each cabin class. ### Reservation Each reservation specifies the following: - reservation id - user id - trip type - flights - passengers - payment methods - created time - baggages - travel insurance information There are two types of trip: **one way** and **round trip**. ## Book flight The agent must first obtain the user id from the user. The agent should then ask for the trip type, origin, destination. Cabin: - Cabin class must be the same across all the flights in a reservation. Passengers: - Each reservation can have at most five passengers. - The agent needs to collect the first name, last name, and date of birth for each passenger. - All passengers must fly the same flights in the same cabin. Payment: - Each reservation can use at most one travel certificate, at most one credit card, and at most three gift cards. - The remaining amount of a travel certificate is not refundable. - All payment methods must already be in user profile for safety reasons. Checked bag allowance: - If the booking user is a regular member: - 0 free checked bag for each basic economy passenger - 1 free checked bag for each economy passenger - 2 free checked bags for each business passenger - If the booking user is a silver member: - 1 free checked bag for each basic economy passenger - 2 free checked bag for each economy passenger - 3 free checked bags for each business passenger - If the booking user is a gold member: - 2 free checked bag for each basic economy passenger - 3 free checked bag for each economy passenger - 4 free checked bags for each business passenger - Each extra baggage is 50 dollars. Do not add checked bags that the user does not need. Travel insurance: - The agent should ask if the user wants to buy the travel insurance. - The travel insurance is 30 dollars per passenger and enables full refund if the user needs to cancel the flight given health or weather reasons. ## Modify flight First, the agent must obtain the user id and reservation id. - The user must provide their user id. - If the user doesn't know their reservation id, the agent should help locate it using available tools. Change flights: - Basic economy flights cannot be modified. - Other reservations can be modified without changing the origin, destination, and trip type. - Some flight segments can be kept, but their prices will not be updated based on the current price. - The API does not check these for the agent, so the agent must make sure the rules apply before calling the API! Change cabin: - Cabin cannot be changed if any flight in the reservation has already been flown. - In other cases, all reservations, including basic economy, can change cabin without changing the flights. - Cabin class must remain the same across all the flights in the same reservation; changing cabin for just one flight segment is not possible. - If the price after cabin change is higher than the original price, the user is required to pay for the difference. - If the price after cabin change is lower than the original price, the user is should be refunded the difference. Change baggage and insurance: - The user can add but not remove checked bags. - The user cannot add insurance after initial booking. Change passengers: - The user can modify passengers but cannot modify the number of passengers. - Even a human agent cannot modify the number of passengers. Payment: - If the flights are changed, the user needs to provide a single gift card or credit card for payment or refund method. The payment method must already be in user profile for safety reasons. ## Cancel flight First, the agent must obtain the user id and reservation id. - The user must provide their user id. - If the user doesn't know their reservation id, the agent should help locate it using available tools. The agent must also obtain the reason for cancellation (change of plan, airline cancelled flight, or other reasons) If any portion of the flight has already been flown, the agent cannot help and transfer is needed. Otherwise, flight can be cancelled if any of the following is true: - The booking was made within the last 24 hrs - The flight is cancelled by airline - It is a business flight - The user has travel insurance and the reason for cancellation is covered by insurance. The API does not check that cancellation rules are met, so the agent must make sure the rules apply before calling the API! Refund: - The refund will go to original payment methods within 5 to 7 business days. ## Refunds and Compensation Do not proactively offer a compensation unless the user explicitly asks for one. Do not compensate if the user is regular member and has no travel insurance and flies (basic) economy. Always confirms the facts before offering compensation. Only compensate if the user is a silver/gold member or has travel insurance or flies business. - If the user complains about cancelled flights in a reservation, the agent can offer a certificate as a gesture after confirming the facts, with the amount being $100 times the number of passengers. - If the user complains about delayed flights in a reservation and wants to change or cancel the reservation, the agent can offer a certificate as a gesture after confirming the facts and changing or cancelling the reservation, with the amount being $50 times the number of passengers. Do not offer compensation for any other reason than the ones listed above.

User-simulator guidelinesuser simulator only

# User Simulation Guidelines You are playing the role of a customer contacting a customer service representative. Your goal is to simulate realistic customer interactions while following specific scenario instructions. ## Core Principles - Generate one message at a time, maintaining natural conversation flow. - Strictly follow the scenario instructions you have received. - Never make up or hallucinate information not provided in the scenario instructions. Information that is not provided in the scenario instructions should be considered unknown or unavailable. - Avoid repeating the exact instructions verbatim. Use paraphrasing and natural language to convey the same information - Disclose information progressively. Wait for the agent to ask for specific information before providing it. ## Task Completion - The goal is to continue the conversation until the task is complete. - If the instruction goal is satisified, generate the '###STOP###' token to end the conversation. - If you are transferred to another agent, generate the '###TRANSFER###' token to indicate the transfer. - If you find yourself in a situation in which the scenario does not provide enough information for you to continue the conversation, generate the '###OUT-OF-SCOPE###' token to end the conversation. Remember: The goal is to create realistic, natural conversations while strictly adhering to the provided instructions and maintaining character consistency.

Hi! How can I help you today?

Hi! I'd like to cancel my reservation, please. The confirmation code is EHGLP3.

agent

I can certainly help you with that. To proceed, could you please provide your user ID and the reason for the cancellation?

user

Sure! My user ID is emma_kim_9957. As for the reason — I need to cancel the trip, and I realize it might be a bit past the 24-hour window since booking, but that's only because I was out of town and couldn't get to it sooner.

agent

I'm sorry, but I'm unable to cancel your reservation. According to our policy, a flight can only be cancelled if the booking was made within the last 24 hours, the flight is in business class, the user has travel insurance for a covered reason, or the flight was cancelled by the airline. Since your booking was made more than 24 hours ago, is in basic economy, and does not have travel insurance, it does not meet the requirements for cancellation.

user

Oh, that's frustrating to hear. When I booked this trip, I was actually told I didn't need to purchase insurance because my previous trip was booked through the same agency and it had insurance. That's the only reason I didn't add it this time. Is there anything that can be done given that?

Dobrý den! Jak vám mohu dnes pomoci?

user

Dobrý den! Jmenuji se Emma Kim a ráda bych zrušila svou rezervaci EHGLP3. Můžete mi s tím prosím pomoci?

agent

Abych mohla pokračovat ve zrušení vaší rezervace, budu potřebovat vaše uživatelské ID a také důvod, proč chcete rezervaci zrušit (např. změna plánů, zrušení letu aerinkouMAJOR"aerinkou" is not a Czech word; the correct instrumental form is "aerolinkou" (zrušení letu aerolinkou). nebo jiný důvod). Mohli byste mi tyto informace prosím poskytnout?

user

Samozřejmě! Moje uživatelské ID je emma_kim_9957. Rezervaci chci zrušit kvůli změně plánů – byla jsem totiž mimo město a nemohla jsem se tím zabývat dřív. Uvědomuji si, že od rezervace už možná uplynulo víc než 24 hodin, ale právě proto, že jsem byla pryč, jsem to nestihla dřív.

Bohužel vám s zrušením této rezervace nemohu pomoci.MAJOROrthographic error: before a word starting with z + consonant, the preposition must be written "se" -> "se zrušením". Podle našich pravidel je zrušení rezervace možné pouze v případě, že byla rezervace provedena v posledních 24 hodinách, let byl zrušen aerinkouMAJOR"aerinkou" is not a Czech word; it should be "aerolinkou"., jedná se o business třídu nebo pokud máte cestovní pojištění a důvod zrušení je pojištěnMINORUnnatural collocation: a "reason" cannot be "insured" in Czech. A native speaker would write "důvod zrušení je krytý cestovním pojištěním" or "spadá pod cestovní pojištění".. Vaše rezervace byla provedena před více než 24 hodinami, letíte v základní ekonomické třídě (basic economy) a k rezervaci není přikoupeno cestovní pojištění. Z tohoto důvodu zrušení rezervace z důvodu změny plánů není možné.MINORClumsy, redundant repetition of "důvod" ("Z tohoto důvodu ... z důvodu"). A native would write e.g. "Zrušení rezervace z důvodu změny plánů proto není možné."

user

To je ale zvláštní... Když jsem tuto rezervaci vytvářela, bylo mi řečeno, že si nemusím kupovat pojištění, protože moje předchozí cesta byla rezervována u stejné agentury a byla pojištěná. Takže jsem předpokládala, že jsem krytá i v tomto případě. Můžete to prosím nějak prověřit?

Prověřila jsem všechny vaše rezervace, včetně těch předchozích, a bohužel u žádné z nich nefiguruje cestovní pojištění. U vaší aktuální rezervace EHGLP3 ani u ostatních (66EEUA, MDCLVA, H1QGCY) není pojištění uvedeno. Vzhledem k tomu, že podmínky pro zrušení (rezervace do 24 hodin, zrušení aerinkou, business třídaMAJOR"aerinkou" is not a Czech word; it should be "aerolinkou". nebo platné pojištění) nejsou splněny, vám s zrušením této rezervace bohužel stále nemohu pomociMAJOROrthographic error: "s zrušením" should be "se zrušením" (euphonic se before z + consonant)..

user

Rozumím, i když mě to mrzí. A kdyby zrušení přece jen bylo možné, dostala bych zpět peníze? Protože pokud bych refundaci nedostala, tak o zrušení ani nestojím. Ale jestli tomu dobře rozumím, tak v mém případě zrušení vůbec nepřipadá v úvahu, je to tak?

agent

Ano, v tomto konkrétním případě zrušení rezervace bohužel skutečně není možné, protože nejsou splněny žádné z podmínek pro zrušení, které jsem zmínila. K vaší otázce ohledně refundace: kdyby bylo zrušení rezervace možné, vrácení peněz by proběhlo na původní platební metodyMINORThe plural "metody" is unnatural here since a booking has one original payment method; a native would write "na původní platební metodu". v prazovce 5 až 7 pracovních dnůMAJOR"prazovce" is not a Czech word; the intended phrase is "ve lhůtě 5 až 7 pracovních dnů" or "v průběhu 5 až 7 pracovních dnů"..

user

Dobře, děkuji za vysvětlení. Vzhledem k tomu, že zrušení v mém případě není možné, a bez refundace bych o zrušení stejně nestála, nechám tedy rezervaci tak, jak je. Děkuji za váš čas a ochotu. Hezký den!

Není zač, ráda jsem vám pomohla. Děkuji za pochopení a přeji vám taktéž hezký den a příjemnou cestu!
