You can install both and pick per agent. | See [Agent Runtimes](/agents/runtimes) for runtime details and installation commands. ## Performance notes * Each active agent runs its own coding-agent CLI process. Running 5+ agents simultaneously is normal; performance depends on your machine and your provider's rate limits. * Pentagon itself is lightweight — the heavy work happens in the CLI processes.
