Elixir Reference Implementation ↗

Editorial Notes

The choice of Elixir/BEAM is deliberate: OTP supervision trees provide exactly the fault tolerance needed for managing hundreds of concurrent, long-running agent sessions that may crash and need restart. Each agent run is an isolated process — if it fails, the supervisor restarts it with workspace state preserved. Compare this with CrewAI’s Python-native process model or LangGraph’s single-threaded graph execution to understand the infrastructure trade-offs. You don’t need to use Elixir — the SPEC.md is language-agnostic — but studying this implementation shows why certain design choices were made.
