What is this?
coop is a Rust CLI that spins up disposable, isolated virtual machines so Claude Code and Codex can run with full tool access (Docker, git, compilers, package managers) without putting your host machine at risk.

Linux arm64 builds exist but are untested, and each backend has its own host prerequisites.

Claude Code and Codex are both supported, each with its own integration documentation.Why use a VM instead of just a container?A VM gives the agent full tool access including Docker, compilers and package managers while keeping it fully isolated from the host kernel, which a shared-kernel container can't guarantee.
