-`FLYTE_DEV=True` is required when you intend to run the manager locally — it disables the in-cluster manager so your local process can take over. The value is case-sensitive: `FLYTE_DEV=true` leaves the in-cluster manager running alongside yours. `make devbox-run` writes a kubeconfig pointing at the devbox cluster in global kubeconfig, so `kubectl` will target it automatically.
