By no means idiot-proof (since they'll always build a better idiot), but, to help me avoid being the source of tragedy:
Use different colors for dev xterms and prod xterms
Use per-TTY shell-history files (so no accidents happen via lazy shell-history executions)
Use different cloud-accounts to host dev and production services
If using web UI, only ever open dev and prod in specific browsers and/or profiles/sessions
If using CLI, make sure that each command is executed with a specific profile-name for each account and role
If your CSP supports it, enable termination protection on prod resources
Ensure use of "obvious" naming-patterns for dev and prod resources - both at the cloud-layer and within resources (instance hostnames; DB intance-names; etc.)
For further actions, you may consider blocking this person and/or reporting abuse
