Summary

Preview CLI reminders that help users keep a backup way into their Supabase account. After a successful interactive command, a reminder appears on stderr and links to Account Security to generate or regenerate recovery codes.

The scaffold covers three cases:

Mock value	Intended account state	Reminder
missing	No recovery-code set has been generated	Generate and save a set
low	One to three unused recovery codes remain	Generate and save a new set
exhausted	No unused recovery codes remain	Generate and save a new set

These are opt-in previews selected with SUPABASE_ACCOUNT_RECOVERY_REMINDER_MOCK=missing, low or exhausted. The flag selects the message directly. Account eligibility and code counts will come from the future API.

Reminders are suppressed for CI, detected coding agents, help/version requests, machine-readable output and non-interactive terminals. They leave command stdout and exit codes intact.

Remaining integration

Live reminders need an authenticated account-recovery API, including eligibility rules for verified backup factors, SSO-managed accounts and feature availability. The CLI also needs account-specific throttling so it does not repeat the reminder after every command.

The three preview cases establish the CLI presentation. The backend contract and reminder cadence still need agreement before live checks are enabled.
