Claude Code 2.1.224 Quietly Removed the 200-Subagent-Per-Session Spawn Cap
Releasebot·medium signal
Buried under the self-hosted-runner headline in Claude Code 2.1.224 (August 7) is a change that matters for anyone running long autonomous loops: the 200-subagent-per-session spawn cap is gone, so long-running sessions no longer start refusing new agents mid-run. Concurrency and depth limits still apply, so this raises the session-lifetime ceiling rather than the parallelism ceiling. If you previously worked around this by chunking work into fresh sessions or restarting harnesses on a timer, that scaffolding can now be removed.
