Claude has hidden codes and almost nobody talks about them.

I've been using these daily. They changed how I work.

5 you should know right now:

ULTRATHINK - type it anywhere, Claude thinks 10x harder.

/caveman - cuts 75% of output tokens. Your bill drops fast.

/insights - analyzes all your past sessions, tells you how to improve.

/loop - schedules a task to repeat on its own.

/btw - ask Claude something while it's already working. It won't cancel the current task.

These aren't in any official getting started guide. They're built into Claude Code for people who dig.

Stop using Claude the default way.

Start using the codes.
