# @open-matrix/cli Package-author CLI for the Matrix SDK layer. This package owns the SDK/package-author `matrix` binary. It does not depend on Matrix-3 product packages, Host Service, Host Control, system actors, HiveCast, Device Link, or NATS authority packages. Initial command surface: ```bash matrix init [dir] matrix add actor matrix actor matrix configure --key --cloud --space matrix run --mount matrix invoke [json] ``` `matrix run` starts a standalone actor runner in the current folder. `matrix invoke` sends a Matrix request envelope to that runner through its local control port. Managed Runtime Host promotion belongs to the later Matrix-3/Runtime Host repoint phase.
