'skillfully-produced' originates from the combination of 'skillful' and 'produce', where 'skillful' comes from 'skill' meaning 'ability' and '-ful' meaning 'full of', and 'produce' from Latin 'producere' meaning 'to lead forward'.

'Skillful' evolved from Middle English 'skilful', and 'produce' from Latin 'producere', eventually forming the modern English term 'skillfully-produced'.

Initially, 'skillful' meant 'full of skill', and 'produce' meant 'to bring forth', evolving into the current meaning of 'created with expertise'.
