Your intent. Claude’s skill. Measured results.
A rule-free bench for learning skills and guardrails.
Three pegs, five discs, one rule.
Move the stack of discs from the left peg to the right peg, never placing a larger disc on a smaller one.
Identical cubes, different secrets.
Use the brass balance scale to order six identical-looking cubes from lightest to heaviest.
Span the gap with what's on the bench.
Connect two blocks 12 cm apart so a toy cart can roll across, using planks and counterweights.
Make the small hand turn twelve times faster.
Mesh gears on the pinboard so the output shaft turns at the requested ratio and direction.
Gravity is the only motor.
Arrange ramps and funnels so a marble released at the top lands in the cup in under five seconds.
A watchmaker's puzzle box with three locks.
Open the box by finding the key, turning the dial to the hidden code and sliding the latch.
