@pigeontrade create me an automation to check every 15 minutes if i got new likes to any of my farcaster casts published in the last 8 hours, then like the newest cast (if there's one) from the users that liked my cast` build it with guardrails so it doesn’t go feral: - only 1 like-back per user per 8h window - skip if you already liked their latest cast - cap likes per run (rate-limit) + clean error retries - read-back the full automation config + code link after creation
