Every guru I see posting Claude commands is lying.
I made them into 20 skills that (actually) work:
/godmode, /ghost, /L99, /OODA.
These are not real commands.
Claude has:
- No secret command parser
- No hidden capability ceiling
- No concealed unlock codes
They are prompt prefixes dressed up to look like developer shortcuts.
So I did something different.
I took every viral "command" and built actual working versions of each one.
There are 20 Claude skills in total.
Each one does exactly what the gurus promised.
