Cloud coding agents start each task on a fresh machine. Before the agent can run a single test, something has to install the right runtime and start the database, and every platform wants those instructions in its own file. Copilot runs a setup workflow; Cursor builds a Dockerfile. A team that uses two or three agents writes the same setup two or three times, and a mistake usually shows up later as an agent session that goes nowhere.
