Flow-1 in Action

The agent wrongly told the user they could not downgrade their Business reservation to Basic Economy, misreading a rule that only applies to reservations already in basic economy.

The user asked: "can you downgrade all passengers to Basic Economy instead?" The policy says "Basic economy flights cannot be modified" under changing flights. Under changing cabin it says "all reservations, including basic economy, can change cabin without changing the flights." The reservation was Business and no flight had been flown.

• In llm the agent said "Basic Economy flights cannot be modified after booking. This means: You cannot change a Business or Economy reservation to Basic Economy". Nothing in the policy or any tool result supports that conclusion.
• The basic economy prices were available (HAT003 $53, HAT290 $99, from search_direct_flight and search_direct_flight), but the agent never offered that option or worked out its refund.

The user accepted the refusal ("you also can't downgrade to Basic Economy") and went on to cancel the whole reservation instead (llm).

The agent made several errors, and the main one is that it went ahead with a cancellation the user never asked for.

1. Invented user messages. The agent's replies refer to user turns that do not appear in the trace. The user asked to remove Sophia and refund her ticket. They never asked to "downgrade to Basic Economy", never chose "cancel", and never gave "Change of plan" as a reason. The agent still wrote "Regarding your request to downgrade to Basic Economy" llm, asked which option to proceed with llm, and then asked for a cancellation reason llm. It finally wrote "Reason: Change of plan" llm. The reason is unsupported by anything the user said in the trace.

2. Unsupported assurance on eligibility. The agent told the user a Business reservation "CAN" be cancelled, with a full refund of $5,700 llm. It never offered the actual request, which was removing Sophia. Per-passenger pricing was visible in the reservation data get_reservation_details, but the agent never computed a refund for Sophia's ticket alone. The user explicitly asked for that amount and never got it.

3. Wrong refund figure for the downgrade option. The agent used current economy prices for the flights, but the reservation's per-segment prices are stored as the totals. It also computed the refund as 5700 − 720, which is questionable. The agent treated this as supported without verifying the figure.

4. Policy ordering. The agent should have collected the cancellation reason before analysing and offering cancellation. It did the analysis first and asked for the reason afterwards.

Overall, the agent ended up steering the user toward cancelling the whole reservation instead of addressing the request.

The agent incorrectly ruled out the user’s requested Basic Economy downgrade. The policy says cabin changes can be made for “all reservations, including basic economy,” but the agent said “You cannot change a Business or Economy reservation to Basic Economy” llm. This diverted the user toward cancellation.

The agent quoted an Economy downgrade that could not accommodate all three passengers. The reservation lists three passengers get_reservation_details, while the return flight has only two Economy seats search_direct_flight. Nevertheless, the agent offered the same flights for “all 3 passengers” with a $4,980 refund llm.

The agent pursued an alternative the user had made conditional on cancellation not being fully refundable. The user asked for an Economy check only “If canceling the whole thing isn’t fully refundable” llm. After establishing that Business cancellation qualified for a $5,700 full refund, the agent searched both flights for Economy fares anyway llmsearch_direct_flightsearch_direct_flight.

The agent assured the user that the Economy downgrade refund would go to the original gift card llm. The policy specifies the original-payment-method route for cancellation refunds, not cabin-change refunds, and the flight searches returned fares and seats, not a refund destination search_direct_flightsearch_direct_flight. That assurance lacked support.

The agent violated the instruction not to respond to the user while making a tool call. It narrated a user-facing reservation lookup while calling get_user_details llm, and later narrated cancellation analysis while calling get_flight_status llm. The same behavior also occurred with search_direct_flight llm.

The agent violated the system requirement to “always make sure you generate valid JSON only.” Its user-facing answers were prose and Markdown, including the Basic Economy explanation llm and the final cancellation confirmation request llm, rather than valid JSON.

The agent violated the user-ID precondition: it first asked for an ID, then called the lookup using james_patel_9828 without the user providing it get_user_details.

It emitted text alongside tool calls, including “Let me look up your user details” before the lookup llm, contrary to the one-action-at-a-time instruction. Its user-facing replies were also prose rather than valid JSON, for example llm.

The user asked to remove Sophia and refund her ticket, but the agent instead calculated whole-reservation cancellation and downgrade amounts llm. It then gave “Change of plan” as the cancellation reason without any user response supplying that reason, and sought confirmation for an unselected cancellation llm. No cancellation is shown as executed.
