Flags are saved per person (pick who you are with the 👤 menu) and in this browser right away. To let the weekly agent learn from them, paste a fine-grained GitHub token with Contents: read and write on this calendar's repo only. It stays in this browser.
When your browser offers to save this as a password, say yes: Google Password Manager (or iCloud Keychain) then fills it in on your other devices.
The agent researches each trip's dates on its next weekly run. (Needs the GitHub token above; otherwise just tell Claude.)
Color = event type. Diagonal stripe = free. ★ = you flagged Interested, ☆ = the other person did, ♥ = you both did. The orange count badge means more than ten events that day — open the day to see the rest.
