All your agents are going async

TL;DR
Async agents that outlive HTTP sessions need durable transport — the author pitches session-based pub/sub.
Key Takeaways
- HTTP SSE + Last-Event-ID may already solve durable transport without new infrastructure
- Real problem isn’t transport but non-portable agent session state across tools (JSONL vs SQLite)
- Article buries a disclosure that the solution pitched is the author’s own commercial product (Ably)
Discussion
Top comments:
- [bozdemir]: Half this post is a disguised pitch for Ably — disclosure buried two paragraphs from end
- [TacticalCoder]: Solved problem: $5/month server, SSH, tmux — no new protocol needed
- [tuo-lei]: Agent session state is non-portable across tools — that’s the real blocker, not transport
- [pdp]: Two concurrent agents injecting into each other’s context doesn’t work well in practice
