Error message

Provide --radius (number or point label) or --point (point on circle)

What it means

ArgumentError thrown by geogebra add-circle when neither --radius nor --point is provided; the command has no way to construct a Circle command without a size definition.

Solutions

1. Add --radius <number or point label> (e.g. --radius 5 or --radius B)
2. Or add --point <label of a point on the circle> (e.g. --point B)

Example fix

// before
opencli geogebra add-circle --center A
// after
opencli geogebra add-circle --center A --radius 5

if (args.radius === undefined && !args.point) {
  throw new Error('add-circle requires --radius (number or point label) or --point');
}

When it happens

Trigger: Running add-circle with only --center (or nothing sizing-related), reaching the else branch at clis/geogebra/add-circle.js:39.

Common situations: Forgetting the sizing flag; a wrapper script dropping empty/undefined arguments before invoking the CLI.
