The Courier is a critial part of the bloodline of your colony. They will run from worker’s hut to Warehouse to worker’s hut, visiting all your workers and delivering the tools and materials they need as well as taking their production to the Warehouse.
The level of the Courier’s Hut will dictate how much materials/tools the Courier can carry to/from Huts - Warehouse - Huts, so if you want them to carry more materials/tools, upgrade the Courier’s Hut. Also, the higher the level of the hut, the faster the Courier will run.
