The num_pins parameter is defined in the schema (line 8) but never validated or used in the function implementation. The function always generates exactly 2 pads regardless of this parameter value. This creates a misleading API where users might expect to configure the pin count, but changes to this parameter will be silently ignored.

If num_pins should be fixed at 2, remove it from the schema:

export const led2835_def = z.object({
  fn: z.string().default("led2835"),
})

Or if it should be configurable, the schema needs to be parsed and the parameter needs to be used:

const parsed = led2835_def.parse(parameters)
const numPins = parsed.num_pins
// Then generate pads based on numPins
Suggested change
export const led2835_def = z.object({
fn: z.string().default("led2835"),
num_pins: z.number().default(2),
})
