Some items require certain conditions to be improved. For example, [[smithing]] items need to be [[glowing hot]] to improve. Also, all items need to be at 0 [[damage]] (repaired) to be improved.
Some items cannot be improved and will reflect that when the examine command gives no information for improvement: [[newbie "]] [[starter kit" ]] tools, most building materials ([[dirt]], [[plank]]s, etc), etc.
