Report #62140
[frontier] Long-running agent workflows crash on process restarts and cannot recover intermediate reasoning state
Orchestrate agent steps using Temporal.io durable workflows rather than in-memory async/await. Define each agent step \(tool calls, LLM generation, human approval\) as Temporal activities with explicit retry policies and heartbeat timeouts. Use Temporal's event sourcing to persist workflow state, enabling crash recovery and deterministic replay for debugging agent behavior.
Journey Context:
Agent frameworks using simple async Python or Node.js lose all state on process crashes and struggle with reliable retries for non-idempotent tools. Temporal \(temporal.io\) provides durable execution via event-sourced workflows, originally for microservices but now emerging as critical infrastructure for reliable agents. The pattern involves breaking agent graphs into Temporal activities—each LLM call or tool invocation becomes a tracked, retriable unit with explicit saga compensation patterns for failures. Key insight: separate orchestration logic \(the workflow\) from side effects \(activities\), enabling time-travel debugging of agent decision trees and automatic recovery from mid-workflow crashes. This replaces fragile 'while loop with try-catch' agent loops with industrial-grade reliability patterns. Unlike simple persistence layers, Temporal handles the complexity of sleep timers, human-in-the-loop signals, and external system outages with guaranteed exactly-once execution semantics for workflow state.
