Andrew (@Ra3orbladez) shipped Swarm v0.14.0: it no longer only watches agents—it can steer them. With on_stop=block, when Claude Code finishes a turn in a claimed worktree Swarm runs required repo gates first; on failure it refuses stop and returns the gate name plus output tail (max three refusals, then an incident to avoid burning budget). Permission prompts surface on the dashboard with Allow/Deny, co-editing agents learn of each other’s file edits immediately, idle sessions wake on message, and rules can rewrite commands (e.g. strip git commit --no-verify). Setup: bunx @ra3orblade/swarm setup.

Key Takeaways

  • ✓on_stop=block runs repo gates before Claude Code can stop; red gates refuse stop with feedback (max three).
  • ✓Dashboard Allow/Deny for permission prompts; cross-agent file-edit awareness; idle sessions wake on message.
  • ✓Rules can rewrite commands (e.g. strip --no-verify); install via bunx @ra3orblade/swarm setup.
