How we verify

Evidence: Screenshots or logsThe source shows screenshots, a transcript or the agent's output.

PartialThe source says it only partly worked, or had a significant problem a person had to deal with.

What went wrong: Flight events had the wrong lengths and the reminders needed a second prompt.

Outcome

From a flight confirmation email, Comet Assistant opened Google Calendar and created entries with airports and flight numbers for a NJ–London–Dubai–NJ trip, but the entries didn't span the full flight times and the poster had to fix them by hand and re-prompt for the check-in reminders.

Prompt Improved prompt

Strengthened by us to avoid the problem in the source. Not tested by the poster. It doesn't change what happened in the source.

Run this task now, exactly as written below. Everything you need is here, so start straight away and only stop if something required is missing.

Goal: Put every flight from my confirmation email into my calendar correctly, with check-in reminders.

Fill in before running: Which email, and which calendar?

What I need from you:
- The confirmation email
- Google Calendar access
- Your home time zone

Rules:
- Create one event per flight with departure and arrival in the right local time zones, so it spans the full flight.
- Include flight number, airports and confirmation code in each event.
- Also add a check-in reminder 24 hours before each departure, in the same run.
- Read back every event's start and end time to check.
- Use the departure and arrival times in each airport's local time zone.
- Put the flight number, confirmation code and terminal in the event description.

Output: A list of events created (times with time zones) and reminders.

You'll know it worked when: each event covers the real flight time and every reminder is there.
The prompt they actually used (our rebuild)

The source didn't share its exact prompt, so we wrote this from what it describes.

Add these flights to my Google Calendar as events, and add reminders to check in 24 hours before each flight.
