What could go wrong?
WORSTCASE I'm about to push a database migration that adds a NOT NULL column to a 50M-row users table.
What changes in Claude's response
Claude lists the specific failure modes: 'the migration will lock the table for 20+ minutes', 'every read will block during the migration', 'if it fails halfway you'll have a partially-migrated table that's hard to roll back'. Then it tells you how to avoid each. /WORSTCASE is paranoid mode for high-stakes actions.
