Think of it as three people in a room. One (the director), says: you, with the red shirt, you are now a plane copilot. You, with the blue shirt, you are now the captain. You are about to take off from New York to Honolulu. Action.
Red: Fuel checked, captain. Want me to start the engines?
Blue: yes please, let’s follow the procedure. Engines at 80%.
Red: I’m executing: raise the levers to 80%
Director: levers raised.
Red: I’m executing: read engine stats meters.
Director: Stats read engine ok, thrust ok, accelerating to V0.
Now pretend the director, when heard “I’m executing: raise the levers to 80%”, instead of roleplaying, she actually issue a command to raise the engine levers of a plane to 80%. When she hears “I’m executing: read engine stats”, she actually get data from the plane and provide to the actor.
See how text generation for a role play can actually be used to act on the world?
In this mind experiment, the human is the blue shirt, Opus 4-6 is the red and Claude code is the director.
