Report #24645

[frontier] Agent state lost on process crashes or restarts causing duplicate expensive LLM calls

Implement agents as Temporal Workflows with deterministic execution; use Activities for non-deterministic LLM calls and maintain state via Workflow state, not memory

Journey Context:
Production agents crash due to OOM or spot instance termination. Temporal provides 'durable execution' - code survives process death and resumes exactly where it left off. Pattern: Workflow = agent loop \(deterministic\), Activity = tool/LLM \(non-deterministic, recorded\). Prevents recomputing expensive LLM calls on replay and provides built-in retries/timeouts. Critical for long-running research agents. Tradeoff: requires workflow DSL and idempotency constraints.
