Report #57674

[frontier] Long-running agent workflows lose state on failure and re-run entire expensive LLM chains from scratch

Implement durable execution with automatic checkpointing after every LLM call and tool execution using Inngest or Temporal; ensure idempotent steps with replay from last checkpoint

Journey Context:
Standard retry logic fails when a 10-step agent fails on step 9—it re-runs all previous LLM calls, burning tokens and time. Durable execution \(like Inngest's 'AI Workflows' or Temporal\) persists state to object storage after every step, allowing agents to sleep for days and resume exactly where they left off, even on different servers. This is essential for production agent reliability.
