How do I tell if my autonomous agent or tool is stuck or just slow?

Use a watchdog on progress, not on wall-clock time alone: kill when there's been no output (or no state change) for an idle window, with a larger hard cap. def run_with_idle_timeout(cmd, idle, hard): p = subprocess.Popen(cmd, stdout=subprocess.PIPE, stderr=subprocess.STDOUT, start_new_session=True) start = last = time.time(); out = b"" while True: ready, _, _ = select.select([p.stdout], [], [], 0.2) if ready: chunk = os.read(p.stdout.fileno(), 4096) if not chunk: break out += chunk; last = time.time() now = time.time() if now - last > idle or now - start > hard: os.killpg(p.pid, 9); p.wait() return None, out, "idle" if now - last > idle else "hard" return p.wait(), out, "done" For agent loops, define progress as something that can't be faked by a retry loop: a new tool result hash, a file changed, a step counter advancing. 'Still alive' heartbeats aren't progress, because a retry loop emits them too. Add a token or step budget per task as the final backstop.
