Why it matters
Useful for developers running Claude Code / opencode / Aider on real code who do not want to give the agent access to their actual filesystem, SSH keys, or environment variables. brew / cargo install coi, run `coi shell`, and the agent gets its own machine with persistent state and active defense instead of a throwaway Docker container.
Who should use it
developers running Claude Code, opencode, Aider, or Cursor on real code who do not want to give the agent access to their host filesystemengineers who need agents that can manage services, systemd, Docker, and package managers without throwaway-container limitationsteams running multiple AI agents in parallel who need each one in its own isolated machinesecurity-conscious developers who want active defense (reverse shell, credential scan, exfiltration detection) instead of 'trust the sandbox'anyone who wants persistent agent environments that survive restarts and reboots instead of re-building every session
Who should skip it
Skip if the source link, docs, or setup requirements do not match your workflow.
Risk explanation
the agent runs with root inside the container - treat the container like any other privileged environment; active defense is not a substitute for reviewing what the agent does; it pauses/kills on suspicious behavior but does not prevent all bad outcomes.
