While the 529 errors are server-side, a PostToolUse hook can detect consecutive overload responses and warn before you waste more tokens on retries:
This won't fix the overload itself, but it prevents Claude from blindly retrying (which wastes tokens and makes the overload worse). After 3 consecutive 529s it warns; after 5 it recommends stopping.
