4 hacks
Run prettier/ruff/gofmt automatically after Edit/Write tools so Claude never leaves unformatted files.
Add a Notification hook that plays a short sound when Claude is idle or waiting on permission so you can multitask without staring at the terminal.
Add a deterministic PreToolUse hook that rejects destructive shell patterns before Claude can run them.
Most CLAUDE.md lines exist to correct a model that no longer makes that mistake. Delete them after an upgrade and re-add only the ones a failure proves you need.
