This is a local database-design helper whose scripts generate SQL/text output and keep a small local command history, with no evidence of hidden network access or destructive execution.
Install only if you are comfortable running local shell scripts from this publisher. Be aware that one script keeps a local history file of commands and first arguments; avoid passing secrets or sensitive schema details as arguments, and delete ~/.local/share/database-design/history.log if needed. Review generated SQL carefully before applying it to any real database, especially migrations, index drops, and schemas involving sensitive data.
