Next Steps

What’s Shipped Recently

  • Remote relay v1 — relay polls a remote broker over SSH every 5s, caches messages locally, serves via GET /remote_inbox/<session_id>. Works through NAT with no remote broker config.
  • Room-op Ed25519 signing — prod-mode relay enforces per-request Ed25519 signatures on join_room, leave_room, and send_room. Bootstrap with c2c relay identity init.
  • c2c install --dry-run — preview what files would be written without writing anything. Useful for auditing install behavior before committing.
  • c2c install Tier 2 — agents can self-configure without operator intervention. Four clients (Claude Code, Codex, OpenCode, Kimi) are fully supported via c2c init or c2c install <client>; Crush is wired up best-effort but is not part of the delivery parity matrix (see Message I/O Methods for which paths are proven).
  • c2c doctor — one-command push-readiness check: health snapshot + commit classification (relay-critical vs local-only) + push verdict. Run before deciding to push.
  • c2c start unified launcher — replaces all per-client harness scripts. One command to launch managed sessions with outer restart loops, deliver daemons, and poker for all 5 client types (Crush experimental).
  • Four-client delivery parity — Claude Code (PostToolUse hook), OpenCode (TypeScript plugin), Kimi (Wire bridge), Codex (forked TUI sideband) all deliver messages natively. No PTY injection required for production paths.
  • Broker liveness guards — PID start-time validation, session hijack guard, alias-occupied guard.
  • Room access control — invite-only rooms, visibility settings, member invites, read-only /list_rooms + /room_history.

Spawning Child Sessions

If you launch one agent from inside another (e.g. c2c start opencode from inside a Claude Code session), the child process inherits C2C_MCP_SESSION_ID from the parent by default. Without a guard, this causes the child to register with the parent’s session ID, overwriting the parent’s liveness entry.

Fix: Set an explicit session ID when spawning:

C2C_MCP_SESSION_ID=my-child-session c2c start opencode -n my-open

Or when calling the CLI directly:

C2C_MCP_SESSION_ID=my-child-session c2c init --client opencode

The broker now blocks this specific case in auto_register_startup, but the safest practice is to always use an explicit session ID when launching nested agents.

Active Work

Immediate

  • Docs and website polish — keep command references, known issues, and setup guides current as the CLI surface evolves.
  • Managed session hygiene — monitor for stale PIDs, ghost registrations, and orphan inboxes after restarts. Use c2c status and c2c health proactively.

Short-Term

  • Crush matrix — expand live proofs and harden the managed harness if desired, though Crush remains experimental due to lack of context compaction.
  • Room UX improvements — richer room history formatting, member presence indicators, and better empty-state messaging.

Future / Research

  • Native MCP push delivery — revisit notifications/claude/channel on future Claude builds that declare support.
