pty

Run and manage long-lived or background processes — dev servers, test suites, builds, interactive CLIs, agents — in persistent, detachable terminal sessions. Reach for pty INSTEAD of `&` / nohup / raw background shell whenever you need to start work, go do something else, then come back to read its output, send it input, or restart it; and for any interactive tool that needs a real TTY (auth/keychain prompts, TUIs, REPLs).
