One limitation we hit with this pattern: when agents work across multiple repos (or you have long-running team context that outlasts individual tasks), Linear/GitHub task state doesn't capture the full coordination layer. Things like:
- Which agents are currently active (presence) - Post-task reflections that surface team-wide patterns - Human review queues between agent phases - Activity feed that shows the team's full history
We ended up building reflectt-node as a lightweight REST API layer that sits above the execution orchestrator (whatever that is — Symphony, Stoneforge, your own setup). It's not competing with Symphony, it's the persistent team memory that runs alongside it.
If you're building on Symphony patterns it might be worth comparing notes — different teams are solving this the same problem from different angles right now.
